▼ Taiwan is the type-example of arc-continent collision, with the Luzon Arc on the oceanic Philippine Sea Plate (PSP) colliding with the continental margin of the Eurasian Plate (EUP). In this three-dimensionally complex convergence zone, the PSP subducts to the north beneath the EUP off of northeastern Taiwan, while the EUP subducts to the east beneath the PSP in central and southern Taiwan. The resulting accretion of the Philippine arc crust to the Eurasian continental margin exemplifies an important process in the growth of continents, yet the geometry and structure of the lithosphere at depth are poorly constrained. Some models of the Taiwan orogen propose that thin-skinned deformation above a basal décollement is the dominant deformational style, while other models suggest lithospheric-scale deformation and crustal thickening. This study, conducted as part of the TAiwan Integrated GEophysical Research (TAIGER) project, uses P and S wave receiver functions calculated from teleseismic earthquake data recorded at 30 broadband seismic stations deployed across northern and central Taiwan to detect lithospheric structure and further constrain the style of deformation at the Taiwan orogen. P wave receiver functions suggest the presence of a detachment fault in western central Taiwan continuing eastward from the Western foothills through the Hsueshan Range, and past the Lishan Fault into the Western Central Range. In central Taiwan, P and S wave receiver functions indicate that the crust thickens to the east, with estimated Moho depths increasing from approximately 29 km on the western coast to ~50 km beneath the Central Ranges. On the western coast of northern Taiwan, receiver functions yield an estimated Moho depth of approximately 23 km, with Moho depths increasing to ~40 - 45 km beneath north-central Taiwan. S wave receiver functions indicate that the depth to the base of the Eurasian slab beneath central Taiwan increases from ~100 km beneath the Coastal Plain in the west to ~165 km beneath central Taiwan. The base of the PSP lithosphere beneath eastern central Taiwan is estimated at ~120 km. These new estimates of crustal structure imply thinskinned deformation above a crustal-scale detachment in western Taiwan, with a transition to thicker crust and thick-skinned deformation in central and eastern Taiwan beneath the Hsueshan and Central Ranges.

▼ The Devonian Marcellus "Shale" of the Appalachian Basin is a typical black shale formation with high concentrations of organic matter (maximum Total Organic Carbon, TOC, 14%). Early descriptions of black shales, including the Marcellus, emphasized their homogeneity, high organic matter content, very fine particle size and low energy depositional conditions. Mechanisms that lead to organic matter enrichment (i.e. anoxia, production and sedimentation rate) have been a scientific controversy. Recent studies show that these black shales are not homogenous and display a high degree of variability, and show current-induced deposition. Interdependent processes of preservation, production and sedimentation have been agreed upon rather than one or the other. This study attempts to document the heterogeneity of the Union Springs Formation (within the Marcellus Shale) and focuses on determining depositional conditions that resulted in organic matter enrichment. An integrated high-resolution microfacies, geochemistry and sequence stratigraphical approach is followed in order to achieve this goal. Details are documented in 32 samples collected from fresh, unweathered surfaces of an active rock quarry (Seneca Stone Co.) in Seneca Falls, NY. Utilizing a combination of outcrop observations, hand sample descriptions, optical and scanning electron petrography, and TOC, three lithofacies and thirteen microfacies have been identified based on their allochthonous, autochthonous and authigenic components. A geochemical proxy-based approach is followed to predict the bottom water anoxia, distance to detrital source, and biologic productivity. Results show that mechanisms that led to organic enrichment in the Union Springs Formation included the interdependent processes of preservation, production and sedimentation rate. High TOC values, high abundances of redox proxies (Mo, U, V, Cr) and high abundance of framboidal pyrite indicate anoxic to sulphidic bottom waters that lead to preservation of organic matter. Low Si/Al and Ti/Al are indicative of the absence of coarse grain detrital input to the system, which agrees with the petrographical observations. The main agent diluting the organic matter appears to be carbonates (styliolinids, brachiopods, calcisilt grains). During the deposition of the Union Springs Formation, primary biological production was high, as revealed by the prevalence of marine algal cysts in all of the organic-rich microfacies. A high-resolution sequence stratigraphic framework is established for the Union Springs Formation. Small-scale (<50 cm) stratigraphic stacking patterns are recognized based on the microfacies distribution (grain size distribution, shell bed distributions, black shale-carbonate concretion cycles, and diagenetic components). Based on the sequence stratigraphy, first deepening then shallowing base level is interpreted. The Union Springs Formation constitutes an interval of Transgressive Systems Tract and Highstand Systems. This interpretation agrees with the sequence stratigraphic models of the… Advisors/Committee Members: Jordan, Teresa Eileen (chair), Allmendinger, Richard Waldron (committee member).

▼ I have used geological, geophysical and engineering methods to explore mechanisms of upper plate, brittle deformation at active forearc regions. My dissertation particularly addresses the permanent deformation style experienced by the forearc following great subduction ruptures, such as the 2010 Mw8.8 Maule, Chile and 2011 Mw9.0 Tohoku, Japan earthquakes. These events triggered large, shallow seismicity on upper plate normal faults above the rupture reaching Mw7.0. First I present new structural data from the Chilean Coastal Cordillera over the rupture zone of the Maule earthquake. The study area contains the Pichilemu normal fault, which produced the large crustal aftershocks of the megathrust event. Normal faults are the major neotectonic structural elements but reverse faults also exist. Crustal seismicity and GPS surface displacements show that the forearc experiences pulses of rapid coseismic extension, parallel to the heave of the megathrust, and slow interseismic, convergence-parallel shortening. These cycles, over geologic time, build the forearc structural grain, reactivating structures properly-oriented respect to the deformation field of each stage of the interplate cycle. Great subduction events may play a fundamental role in constructing the crustal architecture of extensional forearc regions. Static mechanical models of coseismic and interseismic upper plate deformation are used to explore for distinct features that could result from brittle fracturing over the two stages of the interplate cycle. I show that the semi-elliptical outline of the first-order normal faults along the Coastal Cordillera may define the location of a characteristic, long-lived megathrust segment. Finally, using data from the Global CMT catalog I analyzed the seismic behavior through time of forearc regions that have experienced great subduction ruptures >Mw7.7 worldwide. Between 61% and 83% of the cases where upper plate earthquakes exhibited periods of increased seismicity above background levels occurred contemporaneous to megathrust ruptures. That correlation is stronger for normal fault events than reverse or strike-slip crustal earthquakes. More importantly, for any given megathrust the summation of the Mw accounted by the forearc normal fault aftershocks appears to have a positive linear correlation with the Mw of the subduction earthquake - the larger the megathrust the larger the energy released by forearc events.

▼ The Kassandra Mining District in northern Greece hosts the Skouries porphyry Au-Cu deposit and intrusion-related carbonate-hosted replacement sulfide orebodies at the Madem Lakkos, Mavres Petres, and Olympias deposits. Igneous suites of late Oligocene (25-27 Ma) and early Miocene (19-20 Ma) age are defined through zircon U-Pb geochronology and whole-rock geochemistry. Both suites exhibit high-K calc-alkaline geochemistry, but the early Miocene porphyries have a shoshonitic affinity. Normalized rare earth element patterns indicate that the late Oligocene suite was influenced by plagioclase fractionation, whereas amphibole-garnet fractionation was important during the early Miocene event. The location and morphology of the sulfide deposits are controlled by a preexisting ductile structural architecture with ductile to brittle faults interacting with chemically reactive marble host rocks. The sulfide orebodies at the Olympias and Madem Lakkos deposits resulted from the intersection of ductile fabrics and fold hinges with extensional mylonites and semi-brittle shear zones. Ore lenses at the Mavres Petres deposit are restricted to fault-imbricated marbles contained within the Stratoni fault zone. Hydrothermal alteration associated with sulfide deposition occurred between 24 Ma and 22 Ma based on 40Ar-39Ar muscovite ages. Kinematic fault-slip analysis and field relationships suggest that sulfide mineralization within the Stratoni fault zone was controlled by north-south extension, whereas a younger phase of mineralization was influenced by east-west extension. The early Miocene Skouries porphyry stock, hosted by a folded gneiss-schist sequence, was localized within the steeply dipping limb of a preexisting district-scale antiform. Northeast-striking porphyry dikes and sheeted veins within the stock indicate that Au-Cu mineralization occurred in response to northwest-southeast directed extension. Structural crosscutting relationships, geochronological ages, carbon-oxygen isotopes, fluid inclusions, and metal distribution patterns suggest that the late Oligocene hydrothermal system within the Stratoni fault zone was centered to the southeast of the Madem Lakkos deposit with an isolated hydrothermal system located to the east of the Olympias deposit. Porphyry Au-Cu mineralization culminated about 4 m.y. later, but was restricted to the Skouries stock. Polymetallic carbonate replacement sulfide and porphyry Au-Cu ore formation corresponds to late Oligocene and early Miocene magmatic events that manifested within the back arc environment in a post-collisional tectonic setting.

▼ The Argentine Precordillera is a foreland fold-and-thrust-belt in western Argentina that overlies the central Chilean flat slab region of the subducting Nazca plate. The Precordillera has accommodated shortening over the past ~20 million years; over this time, the Nazca slab evolved from a relatively steep subduction angle to horizontal subduction. Because the shortening in the Precordillera spans the shallowing of the slab, changes in the deformation patterns can provide insight into the relationship between the down-doing slab and the over-riding plate at zones of shallow subduction. In this thesis, I present field-based structural data, cross sections of the Precordillera, and estimates of shortening magnitude and rates for the region in an effort to characterize the impact of a shallowing slab on deformation at the surface. ! To calculate shortening magnitudes for cross sections that have rigorous uncertainty estimates, I developed an algorithm that propagates known input uncertainties through an area balancing calculation and yields both Gaussian and maximum uncertainty estimates. The area balancing method is complementary to the line-length balancing method and allows one to include known initial uncertainties, such as the uncertainty on stratigraphic thicknesses and the location of the decollement, neither of which are included in the "minimum shortening" estimates often cited in line-length balanced shortening calculations. ! I constructed two cross sectional profiles through the Precordillera to determine shortening magnitude and rates since 20 Ma. Calculations for the profiles yield ~115 ± 44 (100) km of shortening in the Precordillera, where the uncertainty values are both Gaussian and maximum respectively. This shortening magnitude agrees with other published values of shortening for the Precordillera (72 - 136 km) determined via linelength balancing, and the variation in published values falls within the calculated uncertainty estimates. Variations in shortening rate throughout the Precordillera correlate temporally with changes in the geometry of the Nazca slab. Prior to the shallowing of the slab, the Precordillera accommodated 2 - 3% of the total plate convergence; after the slab began to shallow, shortening in the Precordillera accommodated 10 - 12% of the convergence rate.

▼ Geothermal energy is a clean, renewable source of energy found in Earth’s subsurface. There is inherent financial risk in the exploration and production of geothermal energy, primarily due to the high cost of drilling and the uncertainty in reservoir flow properties. Repurposing existing data from the petroleum industry has the potential to reduce uncertainty in geothermal exploration, and may lead to the identification of suitable geothermal prospects in Earth’s widespread sedimentary basins. The Appalachian Basin of the eastern United States provides an opportunity for investigating the potential for low-temperature geothermal energy production, via the reanalysis of existing petroleum reservoir data. A probabilistic analysis of over 1,000 petroleum reservoirs concludes that most hydrocarbon reservoirs in the Appalachian Basin are not suitable for geothermal applications. Furthermore, a validation of these results using natural gas production data concludes that the traditional Productivity Index is not a suitable model for fractured or vuggy lithologies. However, one of the most promising plays in the region is the Trenton-Black River hydrothermal dolomite reservoirs in the Southern Tier of New York. Extensive analysis of existing datasets from a key reservoir in the play—Quackenbush Hill—reveals a highly fractured, heterogeneous, vuggy reservoir with temperatures ~90°C, high horizontal permeability, negligible vertical permeability, and opportunities for stimulation. Assuming these reservoir features are similar for the remainder of T-BR reservoirs, this play has great promise for a petroleum-to-geothermal transition. Finally, a petrographic analysis of matrix and cements from a T-BR structural outcrop analog is conducted to determine the outcrop’s diagenetic similarity to the subsurface reservoirs. The analysis suggests that the outcrop is a diagenetic analog to the subsurface reservoirs, allowing for an application of fracture knowledge from the surface outcrop to the sub-surface T-BR reservoirs. A fracture analysis of that same outcrop provides a better understanding of the fracture spacing in the subsurface, which informs a conceptual model of potential fluid flow in the T-BR reservoirs for future research to more accurately model and predict the flow of geothermal fluids through the T-BR reservoirs.

▼ I mages of surface displacements in response to tectonic forces can provide independent, spatially dense observations that assist in understanding sub-surface processes. When considered independently or augmented with more traditional observations of active tectonics such as seismicity and ground mapping, these measurements provide constraints o n spatially and temporally variable fault behavior across the seismic cycle. Models of fault behavior inferred from these observations in turn allow us to address topics in geologic hazards assessment, the long- a nd short - term character of strain in defor ming regions, and the interactions between faults throughout the crust. In this dissertation, I use remotely sensed observations of ground displacements from interferometric synthetic aperture radar (InSAR) t o approach several problems related to earthquak e and aseismic fault slip. I establish image p rocessing and inverse methods for better detailing subsurface fault slip and apply these to the 2 010 - 2011 Canterbury, New Zealand sequence. Then, I focus on the active tectonics of the Zagros Mountains in south ern Iran. There, I show through orogen -wide InSAR time series analysis that active strain is accommodated across the width of the mountain belt. I also use a combination of InSAR, local seismicity, and structural modeling to demonstrate that strain is v ert ically partitioned within the Zagros fold-and - thrust belt, with earthquakes controlling deformation in the underlying basement while the overlying sedimentary section shortens in t ransient, earthquake- triggered aseismic slip events. In certain examples, th ese aseismic slip events directly contribute to the growth of fault -bend folds. I use these inferences to explore a p reviously noted discrepancy between observed shortening and that which is expected from k nown earthquakes. I show that the earthquakes and short - term aseismic slip cannot account f or this discrepancy, and that additional deformation mechanisms must be active.

▼ Spatially dense maps of coseismic deformation derived from Interferometric Synthetic Aperture Radar (InSAR) datasets result in valuable constraints on earthquake processes. The recent increase in the quantity of observations of coseismic deformation facilitates the examination of signals in many tectonic environments associated with earthquakes of varying magnitude. Efforts to place robust constraints on the evolution of the crustal stress field following great earthquakes often rely on knowledge of the earthquake location, the fault geometry, and the distribution of slip along the fault plane. Well-characterized uncertainties and biases strengthen the quality of inferred earthquake source parameters, particularly when the associated ground displacement signals are near the detection limit. Well-preserved geomorphic records of earthquakes offer additional insight into the mechanical behavior of the shallow crust and the kinematics of plate boundary systems. Together, geodetic and geologic observations of crustal deformation offer insight into the processes that drive seismic cycle deformation over a range of timescales. In this thesis, I examine several challenges associated with the inversion of earthquake source parameters from SAR data. Variations in atmospheric humidity, temperature, and pressure at the timing of SAR acquisitions result in spatially correlated phase delays that are challenging to distinguish from signals of real ground deformation. I characterize the impact of atmospheric noise on inferred earthquake source parameters following elevation-dependent atmospheric corrections. I analyze the spatial and temporal variations in the statistics of atmospheric noise from both reanalysis weather models and InSAR data itself. Using statistics that reflect the spatial heterogeneity of atmospheric characteristics, I examine parameter errors for several synthetic cases of fault slip on a basin-bounding normal fault. I show a decrease in uncertainty in fault geometry and kinematics following the application of atmospheric corrections to an event spanned by real InSAR data, the 1992 M5.6 Little Skull Mountain, Nevada, earthquake. Finally, I discuss how the derived workflow could be applied to other tectonic problems, such as solving for interseismic strain accumulation rates in a subduction zone environment. I also study the evolution of the crustal stress field in the South American plate following two recent great earthquakes along the Nazca- South America subduction zone. I show that the 2010 Mw 8.8 Maule, Chile, earthquake very likely triggered several moderate magnitude earthquakes in the Andean volcanic arc and backarc. This suggests that great earthquakes modulate the crustal stress field outside of the immediate aftershock zone and that far-field faults may pose a heightened hazard following large subduction earthquakes. The 2014 Mw 8.1 Pisagua, Chile, earthquake reopened ancient surface cracks that have been preserved in the hyperarid forearc setting of northern Chile for thousands of earthquake… Advisors/Committee Members: Lohman, Rowena B.
