▼ Ancient rift basins host important hydrocarbon-bearing systems worldwide. A review of these systems indicates that the syn-rift reservoirs are commonly clastic, fluvio-deltaic facies with marine-related seals. Although the passive margin systems overlaying many of these basins have been well-studied and exploited, exploration into the deeper rift strata is riskier and relys on seismic surveys with little well or core data. Modern analogues, like the East African Rift System, provide insights into the early stages of rift development, but seismic analysis of ancient rifts is needed to analyze an entire rift cycle. Seismic surveys of the Jurassic sediments of the Dampier Sub-basin image the complete rift stratigraphy and contain well data through most of the syn-rift sediments. The purpose of this study is to better characterize the location and interaction of the reservoir and seal facies within the Dampier Sub-basin using seismic geomorphological techniques. This study focused on the regional play intervals (RPI) within the syn-rift of the Dampier Sub-basin: the J20 RPI, J30 RPI, J40 RPI, and the J50 RPI. The J20 RPI contained an axially prograding delta system, the J30 RPI contained a transverse prograding, coarse-grained delta system, the J40 contained deepwater fans and debrite deposits, and the J50 RPI contained a mix of delta and submarine fan systems. The interpreted syn-rift stratigraphy of the Dampier Sub-basin shows a switch from axial deposition during rift initiation to transverse deposition during rift climax. This change in dominant sediment drainage direction during rift evolution is important for exploration into syn-rift plays, especially since targeting high quality reservoir sands can be a challenge in these systems. Though transverse systems may contain immature sediments, this study shows that they can be significantly sized features and, when sealed in source rock quality shales, potentially productive plays.

▼ The Paleogene synrift sediments in North West Java Basin area are viable and prolific petroleum plays and the exploration of the reservoir within these lacustrine strata likely be a source of future reserve additions, especially in Jatibarang Subbasin. However, they are exceptionally risky and still moderately understood in terms of their quality, extent, and connectivity. This study utilizes an extensive database: 22 wells, 216.408 m core, palynology-biostratigraphy data, 36 2D seismic lines (456 Km), 850 Km2 3D seismic cube to examine links between the structural evolution of the rift basins and the basins’ sedimentary fill architecture, which ultimately reveals the nature of Paleogene hydrocarbon systems in the Jatibarang Subbasin. The Jatibarang Subbasin was formed by the transtensional motion, started as a narrower compartmentalized basin in the Early Eo-Oligocene, turned as a wider depocenter in the Late Oligocene as the trantension angle is increased. The study defines environments of deposition across the basin that include: (a) alluvial fan and fan delta which is located proximal to border faults, turned distally as (b) braided river system (BRS) which is aligned subparallel – parallel with the splay fault, (c) fluvial plain, and (d) turbidite lacustrine. Poor reservoir facies and ineffective seal are two petroleum system elements that found to correspond with the dry wells in the study area. The distal fan facies tend to create poor reservoir facies due to the high frequency of the sand/shale intercalation and the simple shear deformation in the transtensional system creates topography inequality at the end of the rifting period, which consequents the diversity of maximum flooding events during the early post-rift and impacting the different quality of sealing facies. The understandings from this study conclude that the Jatibarang Subbasin still hold several remaining potentials, including future field development and exploration. The understanding about seal inequality across the basin, detail sedimentology variation and specific dimension, as well as a different order of structural orientation, are then found to be extremely helpful in revealing the future reservoir target, trapping integrity and future prospects in this basin Advisors/Committee Members: Wood, Lesli J.

▼ The structural fabric of crystalline crustal rocks, commonly defined by fractures, metamorphic foliation, tabular intrusions, bedding planes, cleavage etc. represent mechanical anisotropy and structural weakness which are exploited by subsequent tectonic and anthropogenic stressing (induced seismicity) events. In this dissertation, two overarching questions are explored: 1.) What are the roles of inherited crustal deformation in the seismogenic release of elastic strain in areas of sporadic and widespread induced seismicity? 2.) What are the controls of structural inheritance on strain accommodation within contractional and multiphase extensional tectonic settings? The first question is explored in the intraplate induced seismicity setting of the Central – Eastern United States (CEUS), and the second question in the Anadarko Basin, Oklahoma, U.S. and the Shire Rift, Southern Malawi, Eastern African Rift System. In this dissertation, field observations, 3-D seismic reflection data, earthquake data, potential field (aeromagnetic & gravity) datasets, and experimental rock mechanics testing are integrated to address the research questions in the different study areas where appropriate. Among several interesting findings, the results of this dissertation work can be summarized as follows: 1.) In areas of sporadic basement-hosted induced seismicity, the geometry, structure, and mechanical stability of the basement faults make them critically susceptible to seismic reactivation. Furthermore, the presence of a regional-scale structural fabric in an area of anthropogenic stress perturbation facilitates the production of widespread regional-scale induced seismicity. 2.) In juvenile multiphase continental rift settings, the structures that are inheritance from the pre-rift basement and the subsequent phases of extension may influence the patterns of lengthening, widening, bifurcation, and even the episodic termination of propagating rifts. Furthermore, the results show that magmatic structures and basement fabrics represent sustained controls on multiphase rift development. Overall, the various studies presented in this dissertation provide compelling evidences suggesting that pre-existing structures and tectonic conditions promote and sustain subsequent crustal deformation and the associated seismicity in regions of anthropogenic stress perturbations (induced seismicity) and active tectonics.

▼ The Otway rift basin is located on the northwest trending passive margin that extends from southeast Australia to the neighboring the Sorell Basin, west of King Island. The formation of the Otway Basin is associated with the breakup of Gondwana during the late Jurassic/early Cretaceous, and the basin comprises two rifting and multiple inversion events reflected by eight basin supersequences. The basin contains sediments deposited from Upper Jurassic to Holocene and the extent of the basin is 150,000 km2, of which 80% lies offshore. Although the eastern Otway Basin has been investigated in both the onshore and the shallow marine section, a tectonostratigraphic framework for the offshore part still needs to be developed in detailed explanation, which will be rewarding for hydrocarbon exploration purposes. This study aims to interpret and reconstruct the structural evolution of the Otway Basin by integrating tectonostratigraphy, well data, 2D seismic profiles, 3D seismic cubes, and 2D structural restorations. Seismic interpretation is performed for each 3D seismic survey by creating structure maps and labeled seismic profiles. Regional structure maps were also generated at each individual basinal phase by using 2D & 3D seismic data together to apply seismic interpretation techniques. Schlumberger`s Petrel software is used for structural and stratigraphic interpretation on 2D and 3D seismic data set provided by Geoscience Australia whereas Midland Valley`s Move software is used for 2D kinematic reconstruction and restoration throughout the basin. Structural characteristics and depocenter developments for rifting phases, fault types, quantification of extension amounts and designation of regional deformation model is conducted within the scope of this study. Different structural trends composed due to two separate rifting phases are mapped and investigated through seismic profiles and four cross sections restored from Investigator 3D Survey from the Offshore Eastern Otway Basin used to calculate extension amounts (IL 300 - 6.63% [2.626 km], IL – 700 11.11% [5.56 km], IL – 1150 11.16 % [5.63 km], IL – 1700 11.05% [5.53 km]). In addition, regional lithospheric extension model is determined by comparing and contrasting with the existed deformation models.

▼ As sediments and volcanic deposits accumulate on Earth's surface, they record information about Earth's climate, the motion of continents, and the evolution of the biosphere. Through the study of ancient stratigraphic sequences, we can gain a window into our planet's varied, and sometimes tumultuous, past. In this dissertation, I employ a combination of field observations, magnetic data, and chemostratigraphic data in the Keweenawan Mid-continent Rift of North America and the Amadeus Basin of Central Australia to study the paleogeography and paleoclimate during and after the transition between the Mesoproterozoic (1.7 to 1.0 billion-years ago) and Neoproterozoic Eras (1.0 to 0.54 billion-years ago). The supercontinent Rodinia formed at the boundary between the Eras and broke apart throughout the Neoproterozoic. Basins that developed as Rodinia rifted apart record large changes in the biogeochemical cycling of carbon and sulfur, the waxing and waning of low-latitude ice sheets, and the progressive oxygenation of the atmosphere that facilitated the evolution of animals. I report high-resolution paleomagnetic data in stratigraphic context from Mamainse Point, Ontario – the most complete succession in the 1.1 billion-year-old Mid-continent Rift. The results demonstrate that previous suggestions of large non-dipolar geomagnetic field components at the time stemmed from low temporal resolution across geomagnetic reversals during a period of rapid plate motion. This result strengthens the framework for evaluating records of tectonics and climate across the Mesoproterozoic/Neoproterozoic boundary. Rock magnetic experiments on Mamainse Point lavas, paired with electron microscopy, demonstrate that a component of the magnetization in oxidized flows that is antiparallel to the characteristic remanence is a result of martite self-reversal. This component is the best resolved natural example of the experimentally observed self-reversal that accompanies the maghemite to hematite transition. This result allows the magnetizations of the lavas to be fully interpreted, and also suggests that this self-reversal phenomena may be more widespread than currently recognized – with its identification in this study being greatly aided by stratigraphic context during a period when North America was moving rapidly towards the equator. Stratigraphic and stable isotope work on the Neoproterozoic Bitter Springs Formation of the Amadeus Basin demonstrates that the negative carbon isotope values of the "Bitter Springs Stage" are tightly consistent in carbonate rocks across more than 400 km. In addition to being present in the isotopic composition of the carbonate, organic carbon isotope values shift sympathetically into and out of the stage thereby supporting the interpretation that the stage is a record of primary changes to the carbon cycle. The stage is bound by sequence boundaries that provide evidence for changes in sea-level and climate. Previous work on correlative stratigraphy from the Akademikerbreen Group of East Svalbard… Advisors/Committee Members: Maloof, Adam C (advisor).

▼ Le propos de cette thèse est d’étudier le rift de l’Atlantique sud au Congo, en se focalisant sur (1) la dynamique des reliefs amont du rift (les épaulements de rift), (2) l’architecture stratigraphique du remplissage sédimentaire et (3) le routage sédimentaire ante- à syn-rift. L’etude de terrain a permis de reconstituer la géométrie des paléovallées, le cadre sédimentaire et stratigraphique du remplissage sédimentaire et de discuter des implications géodynamiques de ces paleovalleys en termes de dynamique du rift et de contrôle des systèmes sédimentaires. Ces paléovallées ont été incisées dans le substratum précambrien du Mayombe par des rivières alluviales pendant la phase d'étirement du rifting et remplies par des sédiments d’âge Aptien moyen de la Formation de Chéla. Le remplissage sédimentaire de ces paléovallées consiste en des faciès gravitaires sousaquatiques interdigités dans les argiles lacustres riches en matière organique, recouvrant en discordante le socle Précambrien du Mayombe. Ces depôts s'organisent en une séquence transgressive, caractérisée par l’empilement des séquences élémentaires de type finning-up . L’analyse sédimentologique de carottes a permis de caractériser les environnements de dépôts des Formations de Pointe-Noire, Pointe-indienne et de Chéla, correspondant à la phase d’hyperextension (sag) de l’evolution du rift. La Formation de Pointe-Noire d’âge Barrémien moyen est constituée des faciès gravitaires de cônes sous-lacustres profonds à dominance argileux et riches en matière organique dans lesquels s’intercalent localement des faciès carbonatés de plate-forme peu profonde et gravitaires resédimentés du membre de Toca, accumulés au cours d'une importante transgression associée à un évènement anoxique général. La Formation de Pointe-indienne d’âge Barrémien supérieur à Aptien inferieur est caracterisée par variations latérales et verticales de faciès. Elle comprend des faciès gravitaires gréso-argileux (membre Mengo) de cônes sous-lacustres profonds, surmontés par des faciès mixtes silicoclastiques et carbonatés de rampe interne à moyenne dominée par des vagues de tempêtes (Membre des Argiles vertes) passant progressivement vers le haut à des faciès deltaïques de Tchibota. La formation de Chéla d’âge Aptien moyen se caractérise par des variations latérales et verticales de faciès. Elle comprend des faciès sous-aquatiques de delta alluvionnaire passant latéralement aux faciès gravitaires sous-lacustres, suivi par des faciès de baies mixtes lacustres -marine, surmontés par des faciès de sabkha (membre Vembo) recourvets par les evaorites de Loémé. Les facies de sebkha au sommet de la Formation de Chéla témoignent d’une incursion marine avant la mise en place des évaporites. Les corrélations stratigraphiques entre puits ont permis de subdiviser la succession sédimentaire de la phase d’hyper-extension (sag) en trois principales séquences de dépôt montrant respectivement des tendances rétrogradante, progradante et rétrogradante.

▼ Lake Nakuru basin is located in Nakuru district in the Central Kenya Rift. The study area extends between the bounds of 35o 50’ 35’’E to 36o 15’ 47.5’’E and 0o 09’ 21.8’’S to 0o 42 ‘ 56.5‘’S The study area is divided into three sub basins namely Nakuru West, Nakuru East and Nakuru North. Nakuru West is generally endowed with a lot of streams traversing it and it contributes a large part of the catchment area that drains into Lake Nakuru. The hydrology of the study area is dependent on the catchment supply through rivers. The objective of this study was to determine spatial variation of chemical (Na, K, Mg, Ca, NO3 SO4, Cl and HCO3) and physical characteristics (pH, TDS and Conductivity) of surface and groundwater quality and the sources of pollutant (SO4, Cl and NO3) in relation to human activities/, soil and geology of Lake Nakuru basin. The approach involved chemical and physical analyses of major ions. A total of 51 deep boreholes, 3 shallow boreholes, 3 springs and 21 river samples were collected and analyzed for the major ionic composition. The data was analyzed and interpreted using SPSS, AquaChem and ArcGis computer programs. The results indicate that chemical composition of dissolved ions are in the increasing order of Na+, K+,Ca2+, Mg2+ (cations) and HCO3-, Cl-, SO42-, NO3- (anions) for both surface water and groundwater. Groundwater is characterized by average mean of 403.99 mg/l TDS, 823.20 µS/cm conductivity and 7.68 pH. Surface water on the other hand is characterized by mean 287.85 mg/l TDS, 577.67 µS/cm and 7.65 pH. From the results it is deduced that there is spatial variation in composition of water resources in the study area. Surface water is Na-HCO3 to Na-Cl facies whereas groundwater is Na-HCO3 to Na-ClSO4 type in the study area. Both surface water and groundwater are fresh and alkaline. Anthropogenic sources of pollution have greatly affected surface water as compared to groundwater. The origin of major ions in groundwater is mostly attributed to weathering of silicate rocks, natural process through precipitaion and anthropogenic contribution is significant. The nonpoint source of pollution of groundwater in the study area It is recommended that interconnection between surface and groundwater should be determined. This will be helpful in future monitoring by giving information on how pollutants move in the environment and extent of water pollution. This is done by injecting a trace element into one of the rivers (e.g river Njoro at its source) in the study area whose flow is structurally controlled. The point along the river into which the element is injected acts as a reference point. The movement of the tracer element to groundwater will be monitored by analyzing samples from the boreholes. Samples that will be found to contain the tracer element in their composition are likely to be interconnected. The above process can be repeated to the other rivers one at a time until the interconnection is determined.

▼ The Albuquerque basin, a part of the central Rio Grande rift, is host to a complex fault network that influences deep and shallow fluid migration. This study examines CO2 flux along these faults at the northern and western borders with the Valles caldera and San Juan basin, using a CO2 flux device with an accumulation chamber (PP-Systems). These major and minor Quaternary faults have damage zones that can influence CO2 degassing, hydrocarbon migration, and groundwater flow and mixing, including geothermal waters related to the Valles caldera geothermal system, ultimately acting as conduits or barriers to fluid flow. Rift systems are known to emit significant amounts of CO2 to the atmosphere, and the location of the central Rio Grande rift accompanied by a relatively recent caldera eruption and the Jemez Volcanic Lineament make this area a field laboratory for examining links between the mantle and surface. To test these hypotheses, 8 sites were targeted, the first 6 of which have springs located along faults: 1) The Valles caldera geothermal system at Sulphur Springs, 2) CO2 rich springs in the caldera at Alamo Canyon, 3) The Soda Dam area of the Valles geothermal outflow plume, 4) Travertine springs of Penasco Springs on the Nacimiento fault, 5) Travertine springs at San Ysidro on the Nacimiento fault, and 6) Travertine springs at Carrizo Arroyo on western rift bounding faults in the area of the Socorro magma body. Two cemented fault zone sites were also targeted: 7) Four faults at the Santa Ana Fault network on the Zia Pueblo and 8) the carbonate cemented Sand Hill fault. There were over 600 CO2 flux measurements taken, in units of grams of CO2 per square meter per day (gCO2/m2d). Collectively, these sites provide a set of transects that allows comparison of CO2 flux from springs and faults north (Alamo Canyon) to south (Carrizo Arroyo) with increasing distance away from the Valles caldera (~ 135 km). Cumulative probability plots were utilized to classify CO2 flux in terms of local background, diffuse, and high point source fluxes (HPSF) at each site. Local background at each site ranges from 0.7 – 4.0 gCO2/m2d (Alamo Canyon), 0.2 – 2.8 gCO2/m2d (Soda Dam), 0.0 – 2.5 gCO2/m2d (Penasco Springs), 0.0 – 1.3 gCO2/m2d (San Ysidro), 0.0 – 1.7 gCO2/m2d (Zia Pueblo), 0.0 – 1.1 gCO2/m2d (Sand Hill Fault), and 0.0 – 1.0 gCO2/m2d (Carrizo Arroyo). Background at Sulphur Springs was uniformly high, possibly the results of an enhanced fault damage zone coupled with an active geothermal system that influences the entire area where measurements were taken. Above background CO2 fluxes are observed in areas around fault zones and are termed diffuse. These moderate CO2 fluxes may be the result of multiple processes surrounding fluid migration and the degassing of CO2 on the surface. A considerable number of these moderate fluxes were measured at most sites except for the carbonate cemented faults at the Zia Pueblo, where one measurement is attributed to a diffuse flux on a silica cemented fault (9.6 gCO2/m2d). Diffuse CO2… Advisors/Committee Members: Crossey, Laura, Karlstrom, Karl, Worthington, Lindsay.

▼ Exposure of humans to arsenic through drinking water may cause health impairment ranging from stomach pain and circulatory problems to skin, lung, bladder, and kidney cancer. Arsenic can enter groundwater from anthropogenic sources, but in many areas of the world, arsenic in groundwater is derived from naturally occurring geologic sources. Elevated arsenic (As) concentrations in groundwater and rocks have been found in crystalline and sedimentary aquifers from New England to Pennsylvania, USA. The Triassic Newark rift basin in New Jersey and Pennsylvania has elevated arsenic concentrations in groundwater and rocks, but little is known about the stratigraphically similar Gettysburg Basin. Researching where arsenic is abundant, why it is abundant and developing simplified ways to monitor arsenic location are important to improving human health, understanding geologic history, and refining contamination assessment techniques. This research uses geochemical signatures, provenance, and iron oxide coated stream pebbles to answer where, why, and how we find arsenic. The Gettysburg basin has 18%-39% of rock samples with arsenic concentrations greater than the crustal average of 2 mg/kg, while the Newark Basin has 73% to 95% of rock samples above the crustal average. The strongest controls on arsenic in rocks of the Gettysburg Basin are the relationship between arsenic and iron and silicon concentrations while the strongest controls in the Newark Basin are the relationship between arsenic and iron and organic carbon concentrations. The groundwater arsenic concentrations follow similarly with 8-39% of water samples from the Gettysburg Basin above 10 µg/L and 24-54% of water samples from the Newark Basin above 10 μg/L. The strongest controls on arsenic in water of the Gettysburg Basin are pH, alkalinity and silicon, while the strongest controls in the Newark Basin are pH and alkalinity. The dichotomy between the arsenic concentrations in the rocks and water of the Gettysburg and Newark Basin is likely from provenance of sediments. The Newark Basin sediments are from terranes equivalent to the Central-Maine and Avalon terranes and Precambrian Grenville basement rocks, which have higher amounts of arsenic. NASC normalized rare earth element spider diagrams show patterns of the Gettysburg Basin data most similar to Iapetus Continental Slope Rise. Plots of La/Th versus Hf, Zr/Sc versus Th/Sc, Eu/Eu* versus LaN/SmN, and Eu/Eu* versus GdN/YbN all show the most overlap with Iapetus Continental Slope Rise, Iapetus Passive Margin, and Accretionary Complex terranes with less from Iapetus Rift Volcanic terranes. Iron-manganese oxide coatings on streambed pebbles in Pennypack Creek, southeastern PA have a significant relationship (p<0.15) with zinc, copper, nickel, and arsenic. Two segments from Pennypack Creek used pebbles and relative discharge from the main stem and two tributaries to predict the arsenic source in the main stem. Results suggest that iron-manganese coated stream pebbles are useful indicators of zinc, copper, nickel and… Advisors/Committee Members: Peters, Stephen C..

A transição entre as duas primeiras fases de rifteamento é caracterizada por um aumento da atividade tectônica e uma reestruturação da bacia. Na Bacia de Sergipe-Alagoas, essa passagem é marcada pela mudança dos sistemas deposicionais e das direções de paleocorrentes entre as Formações Serraria e Feliz Deserto. A sucessão sedimentar estudada pode ser subdividida em três unidades deposicionais que denotam contextos paleogeográficos diferentes. A unidade I, equivalente ao topo da Formação Serraria, é caracterizada por corpos arenosos amalgamados de canais fluviais entrelaçados. A unidade II, correspondente à base da Formação Feliz Deserto, é caracterizada pela intercalação entre associações de fácies de canais fluviais anastomosados e planície de inundação. A unidade III, equivalente à maior parte da Formação Feliz Deserto, é caracterizada por depósitos deltaicos. Os dados de paleocorrentes da unidade I indicam que o depocentro da bacia nessa fase está localizado provavelmente fora dos limites dos atuais estados de Sergipe e Alagoas e a unidade III apresenta um padrão de paleocorrentes polimodal sugerindo influxo sedimentar a partir de vários flancos A baixa quantidade de medidas de paleocorrentes da unidade II não permite tirar conclusões sobre a localização exata do depocentro. A mudança de sistema deposicional e de direção das paleocorrentes sugere que as unidades descritas foram depositadas em diferentes estágios evolutivos de rifte. As unidades I e II foram depositadas em uma ampla bacia rasa durante o Trato de Sistema Tectônico de Início de Rifte (Kuchle e Scherer, 2010) caracterizado por baixa taxa de criação de espaço de acomodação e baixa atividade tectônica. Pode se inferir que esses parâmetros aumentam levemente na unidade II pela preservação de sedimentos finos externos ao canal. A unidade III por sua vez sugere um contexto de bacias mais profundas com alta taxa de criação de espaço de acomodação associada à fragmentação da ampla bacia em meio-grábens distintos. Esse estágio é denominado de Trato de Sistema Tectônico de Desenvolvimento de Meio-Gráben (Kuchle e Scherer, 2010). O contato entre os dois tratos é marcado por uma superfície de inundação indicando que a transição é extremamente rápida e marcada por uma mudança radical na geometria da bacia.

The transition between the first two stages of rifting is characterized by an increase in tectonic activity and a restructuring of the basin. In the Sergipe-Alagoas Basin, this passage is marked by the change of depositional systems and of paleocurrent directions between Serraria and Feliz Deserto formations. The sedimentary succession studied can be subdivided into three depositional units denoting different paleogeographic contexts. Unit I, equivalent to the top of Serraria Formation, is characterized by multy-storey and multi-lateral amalgamated sandstone bodies of braided fluvial channel facies association. Unit II, which corresponds to the base of Feliz Deserto Formation, is characterized by the intercalation between anastomosed fluvial channel and…

▼ Understanding and constraining the growth of normal faults continues to remain a grand challenge for geoscientists. Normal faults have long been interpreted to grow symplistically with an elliptical fault surface growing radially and accrued displacement increasing from the fault tip‐line to the centre of the fault surface. However, continued rigorous analysis of normal fault arrays in rock outcrop and 3D seismic datasets has revealed that normal fault growth is substantially more complex. This is due to the growth and interaction of multiple fault segments, spatial heterogeneity in rock properties and a more detailed three‐dimensional analytical approach to understanding displacement variations, rather than in two‐dimensional analysis in the plane of view. The interpretation of normal fault growth has long been analysed on the centimetre and metre scale in rock outcrop. However, with increasingly available, high quality seismic datasets, constraints on normal fault growth can now be interpreted on the kilometre scale. Our present understanding of small‐scale normal fault growth using rock outcrop is crucial information if we are to constrain the growth of normal faults on the kilometre scale in 3D seismic datasets, with limitations such as data quality, resolution, depth penetration and spatial coverage. Seismic interpretation of normal fault geometry and development, explicitly or implicitly, will be influenced by, and in some cases rely on, preconceived and idealized conceptual models. Continued analysis of high quality seismic datasets, in order to further understand the development of normal fault systems, will create greater predictive ability in seismic interpretation and static modelling of the subsurface when a poorer quality seismic dataset does not provide a complete and obvious answer. Factors controlling normal fault growth, such as crustal extension, gravitational instability, thermal subsidence and sediment loading need to be better understood and constrained to allow for greater prediction of normal fault evolution in any given tectono‐stratigraphic setting. This thesis consists of four papers, each of which analyses the growth of Upper Cretaceous normal fault arrays along Australia’s rifted‐to‐passive southern margin providing implications for other rifted and passive margins around the world, including the North Sea, Suez Rift, East African Rift, Niger Delta, Gulf of Mexico and Baram Delta. Australia’s southern margin and its constituent basins (Bight, Otway, Sorell, Gippsland and Bass basins) was formed from the Australian‐Antarctica continental break‐up since the Middle to Late Jurassic. The four papers comprising this thesis provide analysis, interpretation and discussion on the development of normal fault arrays located in the Ceduna Sub‐ Basin of the Bight Basin and the Gambier Embayment, the present‐day shelf‐edge break and the Shipwreck Trough of the Otway Basin. This thesis aims to qualitatively constrain the influence of controls such as crustal extension,… Advisors/Committee Members: King, Rosalind Clare (advisor), Holford, Simon Paul (advisor), School of Physical Sciences (school).

A Bacia de Campos está limitada pelo Alto de Vitória ao Norte e pelo Alto de Florianópolis ao sul, possuindo uma área de aproximadamente 100.000 km2. Sua seção rifte é composta pela porção basal a mediana do Grupo Lagoa Feia, e inclui a principal rocha geradora da bacia, reconhecidamente rica em matéria orgânica, sendo a maior produtora de hidrocarbonetos do Brasil, e rochas reservatório carbonáticas. O presente estudo foca sua análise no intervalo rifte, onde foi realizada uma interpretação e mapeamento sistemático de linhas sísmicas 2D em uma área chave da bacia. Esta análise é baseada em adaptações de modelos já existentes de evolução de bacias rifte, e nos conceitos de estratigrafia de sequências aplicados à sismoestratigrafia. Através da interpretação e mapeamento das seções sísmicas, foi possível elaborar um modelo evolutivo para a fase inicial da Bacia de Campos, com a elaboração de uma carta cronoestratigráfica e estabelecimento dos tratos de sistemas que distinguem as diferentes fases de evolução dos meio-grábens reconhecidos. O resultado foi a delimitação de três tratos de sistemas tectônicos, que permitiram uma compreensão detalhada da complexa evolução e desenvolvimento das calhas da Bacia de Campos durante a fase rifte.

The Campos Basin is limited northward by the Vitória High and southward by the Florianópolis High, with an area of approximately 100,000 km2. The rift section in the Campos Basin comprises the basal and median portions of the Lagoa Feia Group, and includes the main source rocks in the basin, which is known to be rich in organic matter and is the best hydrocarbon producer in Brazil, as well as carbonate reservoir rocks. The present study focuses its analysis on the rift section, where a systematic mapping and interpretation of 2D seismic lines in a key area of the basin was carried out. This analysis is based on adaptations of existing evolution models for rift basins, and the concepts of sequence stratigraphy applied to seismic stratigraphy. Through the interpretation and mapping of seismic sections, it was possible to propose an evolution model for the initial phase of the Campos Basin, with the construction of a chronostratigraphic chart and the establishment of systems tracts that distinguish different stages on the evolution of the recognized half-grabens. The result was the delimitation of three tectonic systems tracts that allowed the detailed understanding of the complex evolution and trough development of the Campos Basin during the rift phase.

▼ A complex depositional history, related to Atlantic rifting, demonstrates the geological evolution during the late Jurassic and early Neocomian periods in the Araripe Basin NE Brazil. Based on outcrop, seismic and remote sensing data, a new model of the tectono-stratigraphic evolution of the section that covers the stages Dom João, Rio da Serra and Aratu (Brejo Santo, Missão Velha and Abaiara formations) is presented in this paper. In the stratigraphic section studied, ten sedimentary facies genetically linked to nine architectural elements were described, representing depositional systems associated with fluvial, aeolian and deltaic environments. Based on the relationship between the rates of creation of accommodation space and sediment influx (A / S) it was possible to associate these depositional systems with High and Low accommodation system tracks. These system tracks represent two tectono-sequences, separated by regional unconformities. The Tectono-sequence I, which includes lithotypes from the Brejo Santo Formation and is related to the pre-rift stage, is bounded at the base by the Paleozoic unconformity. This unit represents only a High Accommodation System Track, composed by a succession of pelitic levels interbedded with sandstones and limestones, from a large fluvial floodplain origin, developed under arid climatic conditions. The Tectono-sequence II, separated from the underlying unit by an erosional unconformity, is related to the rift stage, and is composed by the Missão Velha and Abaiara Formation lithotypes. Changes in depositional style that reflect variations in the A / S ratio, and the presence of hydroplastic deformation bands, make it possible to divide this tectonosequence into two internal sequences. Sequence IIA, which includes the lower portion of the Missão Velha Formation and sequence IIB, is composed by the upper section of the Missão Velha and Abaiara Formations The Sequence IIA below, composed only by the Low Accommodation System Track, includes crossbedding sandstones interbedded with massive mudstones, which are interpreted as deposits of sandy gravel beds wandering rivers. Sequence IIB, above, is more complex, showing a basal Low Accommodation System Track and a High Accommodation System Track at the top, separated by an expansion surface. The lower System Track, related to the upper portion of the Missão Velha Formation, is composed by a series of amalgamated channels, separated by erosion surfaces, interpreted as deposits of a belt of braided channels. The High Accommodation System Track, correlated with the Abaiara Unit, is marked by a significant increase in the A / S, resulting in the progradation of a system of braided river deltas with aeolic influence. Regarding tectonic evolution, the stratigraphic study indicates that the Tectonosequence Rift in the Araripe basin was developed in two phases: first characterized by a beginning of rifting, related to Sequence IIA, followed by a phase of syndepositional deformation, represented by sequence IIB. The first phase was not… Advisors/Committee Members: Córdoba, Valéria Centurlon (advisor), CPF:59176911691 (advisor), http://lattes.cnpq.br/8212523609187259 (advisor).

O conhecimento estrutural da porção oeste da Bacia Potiguar ainda é incipiente, principalmente aquele relacionado aos sistemas de falhas NW-SE. Esta dissertação analisa o Sistema de Falhas Poço Verde-Caraúbas, onde foi inicialmente individualizado em subsuperfície. As atividades realizadas inerentes a este estudo correspondem à análise de sensoriamento remoto e principalmente à análise geométrica e cinemática, da seqüência pós-rifte da bacia. Além disso, o estudo teve como objetivo determinar os campos de tensão que operam na área. Os estudos foram realizados numa área de 1.000 km, localizada na porção oeste da Bacia Potiguar, ao longo do Sistema de Falhas Poço Verde-Caraúbas, estado do Rio Grande do Norte. As imagens de sensoriamento remoto indicam uma predominância de lineamentos orientados na direção NW-SE, consistente com o sistema de falha em estudo, seguido das direções NE-SW, N-S e E-W. As estruturas tectônicas mapeadas foram analisadas somente em afloramentos da Formação Jandaíra. Eles são juntas (preenchidas ou não) em todas as direções com predominância para o trend NW-SE. Falhas normais de direção aproximada N-S, falhas transcorrentes nas direções NW-SE e NE-SW. A análise geodinâmica identificou dois campos de tensões. O primeiro campo, Campo 1, é representado por uma compressão N-S horizontal e distensão E-W. Este campo atuou na Bacia Potiguar pelo menos até o Mioceno. O segundo campo, Campo 2 é representado por uma compressão horizontal E-W e distensão horizontal N-S. Este é o atual campo de tensões e tem afetado a Bacia Potiguar desde o Plioceno

The structural knowledge of the western portion of the Potiguar Basin is still in its infancy, especially these related to NW-trending fault systems. This paper analyzes the Poço Verde-Caraúbas Fault System, which was initially recognized in subsurface. The activities involved in this study correspond to remote-sensing analysis and, in particular, to the geometric and kinematic analysis of post-rift sequences of the basin. In addition, the study aimed to determine the stress fields operating in the area. The studies were carried out in an area of 1,000 km, located in the western portion of Potiguar Basin along the Poço Verde-Caraúbas Fault System, Rio Grande do Norte State. The remote sensing imagery indicates a predominance of NW-SE-trending lineaments, consistent with the fault system under study, followed by the NE-SW, N-S and E-W directions. The tectonic structures mapped were analyzed only in outcrops of the Jandaíra Formantion. They are joints (filled or not) in all directions, but with predominance of the NW-trending joints. Faults are usually N-S-trending normal faults and NW-SE and NE-SW-trending strike-slip faults. Geodynamic analysis identified two tectonic stress fields: the first field, "Field 1" is represented by an N-S-trending horizontal compression and E-W-trending horizontal extension. This field affected the Potiguar Basin at least until the Miocene. The second field, "Field 2", is represented by an E-W-trending horizontal compression and…

▼ Uma complexa história deposicional, relacionada ao rifteamento do Atlântico, caracteriza a evolução geológica durante o final do Jurássico e o início do Neocomiano na Bacia do Araripe, NE do Brasil. Com base na integração de dados de afloramentos, seções sísmicas e sensores remotos, apresenta-se neste trabalho, um novo modelo de evolução tectono-estratigráfica para a seção que compreende os andares Dom João, Rio da Serra e Aratu (formações Brejo Santo, Missão Velha e Abaiara). Na seção estudada foram descritas dez fácies sedimentares que associadas geneticamente constituem nove elementos arquiteturais, que integram sistemas deposicionais de origem fluvial, eólica e deltaica. Com base na relação entre as taxas de acomodação e aporte sedimentar (relação A/S) foi possível associar estes sistemas deposicionais aos tratos de sistemas de Alta e Baixa Acomodação. Estes tratos de sistemas integram duas tectonosseqüências, as quais estão separadas por discordâncias regionais. A Tectonosseqüência I é composta pelos litótipos da Formação Brejo Santo e se relaciona ao Estágio Pré-Rifte, sendo limitada na base pela Discordância Paleozóica. Tal unidade é formada apenas pelo Trato de Sistemas de Alta Acomodação, caracterizado por uma sucessão de níveis pelíticos intercalados a arenitos e calcários, originados a partir de uma ampla planície fluvial distal, desenvolvida em condições de clima árido. A tectonosseqüência II, separada da seqüência sotoposta por uma discordância erosiva, relaciona-se ao Estágio Rifte, sendo composta pelos litótipos das formações Missão Velha e Abaiara. Mudanças no estilo deposicional que refletem variações na relação A/S, além da presença de bandas de deformação hidroplásticas, permitiram compartimentar tal tectonosseqüência em duas seqüências internas. Seqüência IIA, associada à porção inferior da Formação Missão Velha, e Seqüência IIB, formada pela seção superior da Formação Missão Velha e pela Formação Abaiara. A Seqüência IIA, caracterizada somente pelo Trato de Sistemas de Baixa Acomodação, é composta por arenitos com estratificações cruzadas intercalados a pelitos interpretados como depósitos de um sistema fluvial meandrante grosso. A Seqüência IIB, acima, é mais complexa, sendo formada pelos tratos de sistemas de Baixa Acomodação, basal, e de Alta Acomodação, superior, separados por uma superfície de expansão. O trato de sistemas basal, relacionado à porção superior da Formação Missão Velha, é composto por uma série de canais amalgamados, separados por superfícies de erosão, interpretados como depósitos de um cinturão de canais entrelaçados. O Trato de Sistemas de Alta Acomodação, correlacionado à Formação Abaiara, é marcado por um aumento significativo na relação A/S, que propiciou a progradação de um sistema de deltas de rios entrelaçados, com influência eólica. No que tange à evolução tectônica, o estudo estratigráfico aqui efetuado trouxe à tona que a Tectonosseqüência Rifte na Bacia do Araripe desenvolveu-se segundo duas fases distintas: uma fase de início do rifte, relacionada à Seqüência… Advisors/Committee Members: Valéria Centurion Córdoba, Alex Francisco Antunes, Cláudio Pires Florencio.

▼ As coquinas de bivalves do Grupo Lagoa Feia (Eoaptiano) ocorrem na área sudoeste da Bacia de Campos e constituem reservatórios de hidrocarbonetos. Foram descritos 1030 metros de testemunhos e 368 lâminas delgadas para definir os controles estratigráficos dos eventos e produtos diagenéticos observados e propor um método de predição da paragênese diagenética. Inicialmente foram definidas 34 fácies sedimentares posteriormente agrupadas em 7 associações de fácies nas quais foram reconhecidos os conjuntos de processos geneticamente relacionados, que levaram à interpretação do paleosistema deposicional. Sete produtos eodiagenéticos foram observados na seção informalmente denominada Coquina Inferior e desses, quatro alteram bastante as características permoporosas primárias das rochas, sendo eles: cimentação por calcita blocosa em mosaico, cimentação por sílica microcristalina (quartzo), cimentação por calcedônia e dissolução. Interpreta-se um forte controle do(s) tipo(s) de produto(s) diagenético(s) com a variação do nível base do lago, conforme as seguintes premissas: o cimento de sílica microcristalina ocorre preferencialmente quando o nível base está alto e as rochas sob condições lacustre freáticas, pois, devido ao grande escoamento superficial, o lago neste momento encontra-se enriquecido em Si (proveniente do intemperismo e lixiviação das seções de rochas anteriores), porém ainda diluído (com um volume de água muito amplo), favorecendo a precipitação do quartzo e não da calcedônia. A partir do momento em que o nível do lago cai relativamente, a concentração de Si aumenta e a calcedônia passa a ser o cimento principal. Neste momento, as rochas estão sob condições de ambiente de zona de mistura, pois o nível do lago estaria mais baixo, porém ainda não totalmente em condições de domínio meteórico. A seguir, com nível do lago mais baixo ainda, as rochas passam para o ambiente meteórico e ocorre a precipitação de calcita blocosa (provavelmente necessitando de um tempo de residência baixo, pois o mineral ocorre em todo o intervalo da Coquina Inferior) no meteórico freático, e dissolução no meteórico vadoso. Quando o nível do lago volta a subir, as condições favorecem novamente a precipitação de calcedônia, e, em um nível posterior, mais alto ainda, de sílica microcristalina, iniciando assim um novo ciclo de alterações diagenéticas. A correlação entre a paleobatimetria deposicional da associação de fácies sedimentar e o nível base requerido para determinado(s) tipo(s) de produto(s) diagenético(s) encontrado(s) levou à criação de uma curva de \"velocidade relativa de variação do nível base\", que pôde também ser construída sinteticamente a partir das fácies sedimentares e dos perfis de raios gama e sônico. Tendo em mãos essa curva sintética, foi possível fazer o \"caminho inversoë criar um modelo preditivo (ou seja, sem descrição da diagênese em lâminas delgadas) da paragênese diagenética a partir da associação de fácies sedimentar e da \"velocidade relativa de variação do nível baseëm escala de poço (1D) e também em… Advisors/Committee Members: Renato Paes de Almeida, Paulo Cesar Fonseca Giannini.

Dans les années 1970, J.E.G. Sutton suggérait l’émergence, à partir du 8ème millénaire BC, et à travers la bande sahélo-saharienne et le bassin du Nil, d’un grand groupe culturel aqualithique, caractérisé par certains décors céramiques, des pointes osseuses barbelées, et une économie basée sur la pêche. Celle-ci, en permettant un mode de vie sédentaire, aurait constitué une alternative à la production alimentaire, mais aurait fini par péricliter, principalement en raison de l’aridification du climat. Au contraire, pour J.D. Clark, une économie spécialisée sur une ressource très prévisible aurait pu constituer une étape dans le processus de néolithisation. Cette étude propose de tester les hypothèses de J.E.G. Sutton d’un point de vue économique et de caractériser l’importance de la pêche en fonction des contextes environnementaux, techno-culturels et socio-économiques de l’ensemble de l’Holocène, de la Vallée du Rift au Sahel occidental, grâce à l’étude de quatre principaux sites implantés au coeur et en périphérie immédiate de l’aire de répartition des aqualithiques des J.E.G. Sutton. Ce corpus, comparé à d’autres contextes holocènes de la vallée du Rift, du bassin du Nil et de la zone sahélo-saharienne, a permis de mettre en évidence le fait qu’une économie basée sur la pêche n’est l’apanage ni d’un unique complexe techno-culturel, ni d’une seule zone géographique, ni d’une période climatique, ni enfin d’un contexte socio-économique. Ce type de modèle économique tourné vers les fleuves et les lacs a existé à différentes périodes et a coexisté avec d’autres modèles, davantage centrés sur la chasse, sur l’élevage, ou encore sur une exploitation plus mixte de ces différentes ressources. Il a probablement été un marqueur culturel fort dans certains cas, mais dans des sociétés très éloignées géographiquement, chronologiquement et culturellement, depuis les pêcheurs Early Khartoum et Kansyore jusqu’à, peut-être, ceux des royaumes historiques d’Afrique occidentale.

In the 1970s, J.E.G. Sutton suggested the emergence, from the 8th millennium BC, and throughout the Sahel-Saharan belt and the Nile basin, of a large aqualithic cultural group, characterised by certain ceramic decorations, barbed bone point, and a fishing economy. This, by allowing a sedentary way of life, would have been an alternative to food production, but would eventually have collapsed, mainly because of the aridification of the climate. On the contrary, for J.D. Clark, a specialised economy on a highly predictable resource could have been a step in the neolithization process. This study proposes to test the hypotheses of J.E.G. Sutton from an economic point of view and to characterise the importance of fishing depending on the environmental, techno-cultural and socio-economic contexts of the Holocene, from the Rift Valley to the Western Sahel, through the study of four main sites located at the core and in the immediate periphery of the J.E.G. Sutton aqualithic range. This corpus, compared to other Holocene contexts in the Rift Valley, the Nile basin…

The physical structural modeling tool is being increasingly used in geology to provide information about the evolutionary stages (nucleation, growth) and geometry of geological structures at various scales. During the simulations of extensional tectonics, modeling provides a better understanding of fault geometry and evolution of the tectonic-stratigraphic architecture of rift basins. In this study a sandbox type apparatus was used to study the nucleation and development of basins influenced by previous structures within the basement, variably oriented as regards to the main extensional axis. Two types of experiments were conducted in order to: (i) simulate the individual (independent) development of half-grabens oriented orthogonal or oblique to the extension direction; (ii) simulate the simultaneous development of such half-grabens, orthogonal or oblique to the extension direction. In both cases the same materials (sand mixed with gypsum) were used and the same boundary conditions were maintained. The results were compared with a natural analogue represented by the Rio do Peixe Basin (one of the eocretaceous interior basins of Northeast Brazil). The obtained models allowed to observe the development of segmented border faults with listric geometry, often forming relay ramps, and the development of inner basins faults that affect only the basal strata, like the ones observed in the seismic sections of the natural analogue. The results confirm the importance of basement tectonic heritage in the geometry of rift depocenters

A modelagem estrutural física é uma ferramenta cada vez mais usada na geologia para fornecer informação sobre os diversos estágios evolutivos (nucleação, desenvolvimento) e geometria de estruturas geológicas em várias escalas. No caso particular da simulação da tectônica distensional, a modelagem proporciona uma melhor compreensão da geometria e evolução de falhas e da arquitetura tectonoestratigráfica de bacias rifte. Neste trabalho foi utilizado um aparato tipo caixa de areia para estudar a nucleação e desenvolvimento de bacias influenciadas por estruturas prévias no embasamento, com trend variável em relação à direção de distensão. Para tal, foram realizados dois tipos de experimentos para: (i) simular o desenvolvimento individual (independente) de semigráben com abertura ortogonal ou oblíqua à direção de distensão; (ii) simular o desenvolvimento simultâneo desses semigráben ortogonais ou oblíquos à direção de distensão. Em ambos os casos foi utilizado o mesmo material (mistura de areia e gesso) e mantidas as condições de contorno. Os resultados obtidos foram comparados com um análogo natural representado pela Bacia do Rio do Peixe (uma das bacias interiores eocretáceas do Nordeste do Brasil). Os modelos permitiram observar o desenvolvimento segmentado das falhas de borda, com geometria lístrica, frequentemente formando rampas de revezamento, além do desenvolvimento de falhas internas às bacias localizadas nas suas porções mais basais, similares àquelas observadas nas seções sísmicas do…

▼ This thesis investigates the development of regional drainage patterns within intra-continental rift basins using remote sensing data, field studies and numerical models. By examining modern-day extensional settings, such as the Basin and Range, USA, and the East African Rift System (EARS), this study elucidates the controls upon regional source-to-sink systems and assesses the findings in relation to existing, conceptual tectono-stratigraphic and drainage models. Rift basins are generally well studied and facies models well established. However, there is a tendency to overlook the regional perspective. Many drainage evolution studies and tectono-stratigraphic models focus upon the development of individual basin-bounding faults and half-grabens, often overlooking the influence of regional-scale drainage evolution upon landscape and stratigraphic development. On a regional scale, extensional basins are segmented into numerous sub-basins, which: (i) exist at different elevations; (ii) subside at different rates; (iii) vary in their degree of fluvial connectivity; and, (iv) may experience significant shifts between erosional and depositional regimes as drainage networks evolve. Through observations of the Basin and Range, and three-dimensional numerical modelling, it is shown how sub-basins with identical tectonic and climatic boundary conditions can exhibit vastly different stratigraphic fills depending on the degree of fluvial connectivity and their relationship to adjacent sub-basins. In addition, drainage integration is recognised as an overlooked, yet important process in the source-to-sink evolution of rift basins. Drainage integration between sub-basins of varying elevations is shown to cause widespread erosion and sediment bypass in the upstream basin, while contemporaneously increasing sediment supply to the downstream basin. A case study of the Tecopa Basin shows drainage integration as a powerful driver of base level fall and landscape transience in the absence of significant tectonic or eustatic controls. The differential gradients created by base level fall cause further upstream drainage rearrangements.To understand the evolution of regional hinterland drainages, two rift segments of varying maturity are compared. The Okavango Rift Zone represents a rift initiation phase segment while the Albertine Rift represents a rift climax phase segment. Through analysis of the contributing drainage patterns a model is proposed where early rift drainage is dominated by antecedent directions, with large, low relief, low slope catchments. As rifts mature catchments increase in relief and slope but reduce in asymmetry as the influence of antecedent drainage direction is reduced via tectonic tilting, drainage reversals and ponding.The thesis concludes that current tectono-stratigraphic models of sub-aerial rift settings commonly overlook the role of inter-basin erosion, under-appreciate the influence of antecedent drainage direction in hinterland input, and over-emphasise the role of axial rivers.

▼ The San Luis Basin (SLB) of the northern Rio Grande rift (RGR) is a spectacular intermontane basin in south-central Colorado. The SLB is an east-dipping, half graben basin that formed in response to extension beginning ca. 26 Ma in the Cordillera. Oligocene ash-flow tuffs exposed in the eastern San Juan Mountains and along the western margin of the SLB provide an excellent opportunity to study the kinematic history of the northern Rio Grande rift using paleomagnetism. Outflow deposits of ash-flow tuffs are generally excellent recorders of the geomagnetic field and can be used to study the vertical-axis rotation component of extension related to the opening of the SLB. Four ash-flow tuffs (Carpenter Ridge, Fish Canyon, Chiquito Peak and Saguache Creek Tuffs) that were erupted between ca. 32 and 27 Ma were sampled at a total of 84 sites for paleomagnetic, rock magnetic, and magnetic fabric data. Paleomagnetic data indicate some complexities with using large-volume, regionally extensive outflow deposits of ash-flow tuffs, specifically that relatively thick outflow deposits (with thicknesses exceeding 100 m) may record paleosecular variation of the geomagnetic field. Even with these complications, the four targeted San Juan ash-flow tuffs may still be evaluated for regional domains of potential vertical-axis rotation. Overall, we observe a lack of vertical-axis rotation along the western margin of the SLB. Shear and fault linkage in the hanging wall of the major normal fault of the SLB does not appear to play a role in the evolution of slightly extended terranes. Distal outflow deposits of ash-flow tuffs may also be difficult, if not impossible, to tell apart and paleomagnetism is used to distinguish two units that have, until presently, been grouped together as the Chiquito Peak Tuff. The magnetic fabric of these Oligocene ash-flow tuffs was also measured and analyzed for complexities due to paleotopography and single-domain magnetic carriers. Preliminary results from a comparison between two magnetic fabric techniques are also presented and analyzed. Magnetic fabrics measured for all tuffs in the northeastern San Juan Mountains confirm that their flow was channelized through an Oligocene paleovalley that existed west of Saguache.

▼ This dissertation presents results of an integrated approach including geochronology, paleomagnetism, petrography, x-ray diffraction analysis, depositional environment and sequence stratigraphic interpretation of Oligoceneage continental rift sediments. It provides a convincing analysis of the sedimentary and structural processes involved in the evolution of an Oligocene rift basin and offers inferences for both modern and ancient rift basins. The Chilga rift basin is located in northwestern Ethiopia, between N 12º 25' to 12º 39' latitude and E 37º 03' to 37º 11' longitude. It is a continental rift basin with isolated outcrops of sedimentary and volcanic basin fill separated by faults related to rift processes. Sediments filling the Chilga basin are rich in volcanic ashes, lignite beds, silty sandstones, silty claystones, and vertebrate and floral fossil rich sandstones. Continental rift basins, such as the Chilga basin that contain outcrops which can be correlated with marker beds and that can be dated with a suitable dating method provide a unique opportunity in understanding the tectonic and stratigraphic evolution of rift basins. Correlation and dating of ash beds allows the tectonic and stratigraphic evolution of the Chilga basin to be determined. Radioisotopic and paleomagnetic age dating techniques were used to constrain the age of the basin filling sediments and the underlying basaltic rocks. Results indicate that the Chilga sediments were deposited between 27 – 28.5 Ma. To interpret the depositional environment, the fine-grained Chilga sediments were analyzed using petrographic and x-ray diffraction analysis. Results of the analyses indicate that the Chilga sediments are composed of framework grains of mainly unaltered plagioclase, potassium feldspars, and volcanic rock fragments. The matrix is commonly enriched in kaolinite and illitemontmorillonite and the cement is mainly composed of authigenic siderite and some iron oxide coatings. Interpretations of these characteristics suggest that the Chilga sediments were deposited in alluvial-lacustrine environment with a nearby fine-grained sediment source and indicate a reducing diagenetic environment. A sequence stratigraphic interpretation of the Chilga basin sediments is inferred from the vertical and lateral stacking pattern of stratigraphic units. Key units that were used for the sequence stratigraphic interpretation of the Chilga basin were siderite-cemented silty claystones, which indicate a reducing condition and an increase in lake water depth, and channel incisions and lignite beds, which indicate lake shallowing. The Chilga sedimentary basin records three 4th order sedimentary cycles formed by the rise and fall of the Chilga Lake throughout the course of basin evolution. The identification of normal faults that cut the oldest Chilga sediments, tectonic growth faults, and fault sets that cut the entire Chilga sediment succession indicate that the Chilga basin was tectonically active both during and after… Advisors/Committee Members: Kocurek, Gary (advisor), Kappelman, John W.
