Using Cross-sets for Paleodischarge Estimation and Paleocurrent Vectors in the Parthenon Sandstone, Northwest Arkansas.

▼ In this thesis, set thicknesses are used to estimate the paleohydraulics (paleodischarge and give magnitudes for paleocurrent directions) of the ancient river system which deposited the Parthenon Sandstone in northwest
Arkansas. Set thickness is the vertical thickness of a group of strata conformable series (Mckee and Weir, 1953); set thickness represents truncated dunes. The goal of this thesis is to: 1) obtain paleodischarge estimates of the Parthenon sandstone via cross-sets and compare the results with previously calculated discharge estimates which use basin area to discharge collation techniques and 2) use paleodischarge estimates calculated within this thesis to give magnitude to the paleocurrent direction data and compare the results with, more traditional, non-vector paleocurrent direction data. The quantitative work that has been done on the Parthenon suggests a paleodischarge which differs from qualitative estimates by multiple orders of magnitude; resulting in the need for more research. By obtaining quantitative measurements of set thickness, grain size, and paleocurrent direction on twenty-one Parthenon outcrops (over a 4.5x103 km2 study area), multiple paleohydraulic parameters can be estimated with existing models including: mean bedform height, channel depth, channel belt width, channel width, paleoslope, boundary shear stress, Darcy-Weisbach friction factor, paleoflow velocity, paleodischarge, and overall paleocurrent direction. Paleodischarge estimates in this study average 13,000 m3/s; the minimum estimates average 2,200 m3/s; and the maximum estimates average 53,000 m3/s. Maximum average estimates in this study are lower than the minimum estimates (64,000 m3/s) from past research based on total basin area; estimates in this thesis remain many orders of magnitude larger than any modern flashy system (the type of system the Parthenon has been interpreted as in the past). The overall paleocurrent direction found in this thesis is to the southwest; similar to past analyses. The total mean paleocurrent direction is 211 degrees; the mean of the outcrop means is 191 degree; and the mean of the paleodischarge weighted outcrop means is 198 degrees. There is little change between the overall paleocurrent directions when using vector or just directional data.

▼ This study proposes a hazard/risk index for environmental, technological, and social hazards that may threaten a museum or other place of cultural storage and accession. This index can be utilized and implemented to measure the risk at the locations of these storage facilities in relationship to their geologic, geographic, environmental, and social settings. A model case study of the 1966 flood of the Arno River and its impact on the city of Florence and the Uffizi Gallery was used as the index focus. From this focus an additional eleven museums and their related risk were assessed. Each index addressed a diverse range of hazards based on past frequency and magnitude. It was found that locations nearest a hazard had exceptionally high levels of risk, however more distant locations could have influences that would increase their risk to levels similar to those locations near the hazard. Locations not normally associated with a given natural hazard can be susceptible should the right conditions be met and this research identified, complied and assessed those factions found to influence natural hazard risk at these research sites.

▼ The Glenn Pool Oil Field of Northeastern Oklahoma was established as the first major oil discovery of the fledgling state of Oklahoma. Fully developed by 1912, the field is now nearing depletion even under secondary and tertiary recovery efforts after production for approximately 100 years. Large amounts of residual oil estimated to still be in place have motivated exploration into other recovery methods, including polymer flooding and horizontal drilling. Success of these programs is dependent upon accurate characterization of the reservoir. Because most of the drilling occurred many decades ago, much of the data associated with this field predates electric well logging and has not been integrated with contemporary databases.
To establish a more accurate characterization of the reservoir, these data have been digitized and integrated with current data available to further delineate the Glenn Pool Reservoir. Using information from original drilling records, surveyed well locations, water flood studies, and historical maps, a more sharply defined characterization has been generated for the productive Bartlesville, or Glenn Pool, Sandstone.

▼ In northern Oklahoma and southern Kansas the Reeds Springs Formation (Boone, Mississippian) is a hydrocarbon exploration objective (Mazullo et al, 2011). The Hindsville quarry located in the northeastern portion of Washington County in
Arkansas is the focus of this study. The objective of this study is to characterize the Reeds Spring at the Hindsville Quarry. The use of terrestrial light detecting and ranging(LiDAR) is used to assist in the characterization of the quarry.
The unit architecture within the Hindsville Quarry outlines varying transitional periods that give insight into the deposition of the Reeds Springs Formation. There are comparable formations within the Carboniferous that serve as helpful analogues in explaining the complexities seen in the Hindsville Quarry. Diffusive process (turbidity currents or debris flows) and physical energy flux (winds, waves, and storms) played a large part in defining the sedimentary structures found within the Hindsville Quarry. These mechanisms in depositional process demonstrate that the use of sub aerial exposures are not needed to explain erosive surfaces.
Terrestrial LiDAR is used to identify stratigraphic pattern, bedding planes, and determine the orientation of inaccessible quarry walls. The effects of distance and incidence angle, resolution of the scan, and the ability to discriminate varying lithologies played a role in the assessment of the geologic outcrops. The surveyed dataset allowed detail measurement to be accomplished. The non-contact techniques of investigating geologic outcrops through Terrestrial LiDAR cannot replace transitional methods of geologic investigation, but complement it.

▼ The Mansfield sand is an informally named member of the Pennsylvanian Atoka Formation in
Arkansas. Once a productive gas reservoir, the Mansfield is situated in a double plunging anticline in the southern portion of the Arkoma Basin. The formation is internally composed of sandstone units ranging in thickness from tens of feet to over a hundred feet interbedded with shale units ranging in thickness from several tens of feet to hundreds of feet. Previous studies have focused on the stratigraphy of the lower and middle Atoka. A detailed subsurface study of the stratigraphic framework of the Mansfield sand was conducted using conventional lithostratigraphy and sequence stratigraphy. Four progradational parasequences have been identified within a highstand systems tract. Deposition of the Mansfield occurred in a deltaic environment on a sandy, fluvial or wave dominated shoreline.

▼ Raster log images were analyzed to study the subsurface stratigraphy of the Middle Atoka in the Arkoma Basin of the western portion (Sebastian County) of
Arkansas. The most significant sandstone units of the Middle Atoka in this area were determined to be two generally coarsening-upward sequences in the lower portion of the formation. Based on lithologic correlations, these two units were determined to be the informally named Casey and Freiburg members of the Middle Atoka. Thickness information based on picked tops was used to create isopach maps of the units of interest. The log signatures and geometry of the sand bodies indicate that they were deposited in a deltaic system that prograded across this portion of this basin. Distributary-mouth bar deposits dominate the Casey member, and are occasionally overlain by localized channel deposits. Avulsion of the delta lobe possibly occurred, and a new lobe then began to prograde, depositing the sediments that formed the Freiburg. This unit is also dominated by distributary-mouth bar deposits.

Orbital Periodicities Reflected in Ancient Surfaces of our Solar System and the Implications for a Record of Early Life.

▼ Uniformitarian processes, governed by invariant physical laws, remain the most reliable source for reconstructing the past. Driving many of the repetitive, predictable processes are the orbital dynamics of the Sun-Planet-Moon systems. Astronomical periodicities range from a few hours (tides) to thousands of years (Milankovitch). These periodicities, combined with geomorphic observations of planetary surfaces, constrain the time-dependent processes and allow for reconstruction of events and conditions favorable for sedimentary accumulations. This research suggests that seasonal sedimentary processes are dominant on Titan and Mars, and have played a significant role in the formation of ancient banded-iron formations (BIF's) on Earth.
Earth, Mars, and Titan, the planetary bodies in our solar system with a history of flowing liquids, are characterized here to preserve seasonal and longer-period orbital signatures in layered strata. Surface features also suggest that volatile transient liquids, subject to solid phase sequestering, are dependent not only on climate forcing, but additionally on unique physiographic features of the planetary body. Climate change is subject to longer period orbital oscillations such as precession, eccentricity, and obliquity, and to the rise in or loss of surface liquids (oceans and seas) and atmospheres.
Thickness and mineralogy time-series profiles from the Dales Gorge Member of the Brockman Iron Formation suggest cycles and periodicities similar to modern current velocity profiles. First-order sinusoidal series patterns are interpreted as seasonal changes in bidirectional movement of ocean floor sediment, displaying second-order tidal influence. Sedimentary accumulations consist of iron-dominate organic sequences linked to slower current movement alternating with silica-dominate sequences indicative of modestly higher energy currents. Directional current oscillations may also contribute to changing mineralogy.
Titan and Martian's surfaces also demonstrate active seasonal processes. Rivers within Titan's northern polar region carry sediments from the more distal highland, through rugged foothills, to the lowland basins. Headward erosion during dynamic hydrocarbon seasonal rains carves the present valley and ridge systems on the flanks of the highlands. This research predicts that layered seasonal sedimentary varves have accumulated in the large endhoreic basin in the northern polar region of Titan.

Diagenesis and Reservoir Characterization of the Pennsylvanian Middle Atoka Formation, Sebastian and Logan Counties, West-Central Arkansas.

▼ The Middle Atoka Formation evolved from a stable passive margin during the early Pennsylvanian time to a rapidly subsiding basin, with the sedimentary fill thickening greatly southward during the middle Pennsylvanian time. The basin dips in north-south direction. An east-west anticlines and synclines were observed.
The purpose of this study is to establish the stratigraphic units, reservoir geometry and distribution, and infer the depositional environments and reservoir quality. Well correlation and petrographic studies are used to achieve the goals.
Sandstone Point Count method was used. The Point Counts was divided into five categories. They include the framework grains (quartz, feldspar, and lithic fragments), accessory minerals (muscovite and biotite), cementing materials (quartz overgrowths, feldspar overgrowths, dolomite, and calcite cements), pore-spaces (primary and secondary), and the "Other" (minerals that cannot be identified under the microscope, and matrix and pyrite).
Vertical sequences of sand bodies that are closely spaced and separated by thick marine shale intervals, and sandstones that blocky signatures and abrupt bases and tops, were correlated as genetically related sand bodies. Four stratigraphic units; Borum, Turner, Nichol, and Basham Sandstone Units were identified.
The sandstones of the Middle Atoka Formation are composed of very fine silt to coarse quartzarenites, subarkoses, sublitharenites, and litharenites. The reservoirs are heterogeneous and were divided into two: the amalgamated reservoirs (proximal and medial submarine fans), and the overbank reservoirs (levee-overbank deposits, crevasse splays, and distal lobes). The geometries of the reservoirs are elongate and radial depending on the stratigraphic units. Quartz overgrowths and clay cements are intense and advanced and variable within the two reservoirs.
Porosity loss was significantly caused by compaction and quartz cementation. Secondary porosity, where it occurs, resulted from the dissolution of the labile grains, probably from the interaction with migrating organic acids or as a result of the increasing geothermal gradient. Diagenetic processes either enhance the porosity by dissolving mineral grains, or reducing the porosity by stimulating growth of clay and quartz minerals.
Amalgamated reservoirs contain higher amount of dissolution, clay cements, and lower quartz overgrowths. Dissolutions are filled with clay cements. Dissolution when present in overbank reservoirs are better preserved than is in amalgamated portions. Dissolutions and clay cements are also higher in the south than is in the northern part. Higher clay content in the south ensures that the dissolution is almost effectively occluded by clay cements. Consequently there seem to be no net-gain in porosity despite in the area.

(more)
▼ The State Line Arch is represented by a structural high that trends through the study area in a loose alignment with the
Arkansas-Oklahoma state line. Evidence of the arch extending further to the north includes a structural high and stratigraphic variation at an outcrop on Highway 59 near Evansville Mountain in Crawford County,
Arkansas. The exact timing of the formation of the arch remains undetermined, but upper Devonian thinning at the top of the arch indicates the structure is pre-Mississippian. The reason for the development of the arch is poorly understood, but evidence linking Mississippian-aged Waulsortian mounds to Precambrian Spavinaw granite structures of northeastern Oklahoma and southwestern Missouri suggests Precambrian basement structures may extend into the study area. The structural nature of the arch provided an environment favorable to carbonate build-up during deposition of the Mississippian interval. A previously unidentified limestone unit measuring 175 feet thick likely represents the transgressive phase of a transgressive-regressive sequence responsible for the deposition of the Mayes Group of northeastern Oklahoma. Growth on the downthrown side of the Muldrow-Mulberry Fault system may indicate earlier movement than previous studies have suggested on the east-west trending normal faults of the Arkoma Basin. A possible roll-over anticline structure may exist to the south of the Muldrow-Mulberry fault system.

▼ Mississippian carbonate strata of the midcontinent contain prolific oil and gas reservoirs. Production from these carbonates has been primarily from two reservoir types, the Mississippi "chat" and recently denser chert-rich mudstone intervals. The"chat" interval is a high porosity chert residuum associated with the both the Osagean and basal Pennsylvanian unconformity. The distribution of the "chat" reservoir is discontinuous and heterogeneous. Recent horizontal drilling successes have reinvigorated academic and industry interest in the Lower Mississippian. Much of the activity is now targeting lower porosity, cherty, mudstone intervals of the Reeds Spring and Cowley Formations, which were previously considered to be non-economic.
The study area lies along the shelf edge and slope margin near the Kansas-Oklahoma border comprising all or parts of Alfalfa, Grant, Kay, Woods, and Garfield Counties, Oklahoma. The dataset totals 150 wells with raster image logs. Gamma-ray, resistivity, microlog, photoelectric effect and density logs were all used to make stratigraphic correlations. Reservoir intervals occur near sequence-bounding unconformities that were exposed at periodic lowstands at the top of transgressive-regressive sequences, however, the spatial position and quality has not been well understood in north-central Oklahoma. The purpose of this study is to compile a high resolution sequence stratigraphic study of the Mississippian section from the shelf edge near the state line and south toward the distally starved basin.
Mississippian subcrops are a succession of prograding clinoforms. The compartments are interformational units within the Reeds Spring and Cowley Formations that are individually correlatable. The best quality reservoir is at the tops of shallowing upwards cycles below third and fourth order unconformities. Episodic subaerial exposure provided numerous opportunities for the formation of tripolitic chert reservoirs. There are multiple, distinct clinoforms with reservoir potential in the study area, which differ from conventional chat reservoirs. Reservoir quality clinoforms usually occur near the paleo shelf edge as this was an ideal environment for secondary porosity development during lowstands. Porosity decreases basinward within the wedges and with depth beneath sequence boundaries. Documentation of the spatial extent and quality of reservoir clinoforms within the Lower Mississippian adds value to the exploration and production potential of north-central Oklahoma.

▼ The Boone Formation in northwest
Arkansas and southwestern Missouri exposes a nearly complete sequence of Lower Mississippian chert-bearing carbonates deposited by a single 3rd order transgression and regression. An abundant amount of chert that has replaced limestone highlights the Boone, but little is understood about the timing and development of chert in Lower Mississippian carbonates. Interpretation of the diagenetic history of the chert, in particular tripolite, has significant implications beyond the outcrop. Determining the origin, timing, and extent of tripolitic chert in the Lower Mississippian System improves reservoir characterization in subsurface petroleum reservoirs in the mid-continent that are laterally equivalent to the Boone Formation. The Boone exposures are used as analogs for subsurface carbonate intervals in the Mississippi Lime Play. Results from Petrographic, SEM, EDX, and carbonate weight percent analyses have determined the stratigraphic extent of tripolitization in the Lower Mississippian carbonate succession, as well the controls on tripolite formation. The interpretation that tripolitic chert occurs as a result of a leaching by groundwater and the presence of carbonate controls the development of tripolitic chert can be used to locate highly porous tripolitic chert in analogous carbonate reservoirs in the midcontinent.

▼ The Edwards aquifer is one of the major regional karst aquifers in the United States, with an average withdrawal of 950 million liters per day (
L/d). This investigation focuses on the connection between the Uvalde pool and the San Antonio pool of the Edwards aquifer, known as the Knippa Gap, west of the San Antonio metropolitan area in Uvalde County. This is a major zone of recharge to the Edwards aquifer and is approximately 6.4 km wide. The Knippa Gap is bounded by northeast trending faults of the Balcones Fault Zone (BFZ) on the north (specifically the Cooks and Trio Faults), and uplift from the Uvalde salient and igneous intrusive plugs to the south. Aspects of the hydrogeology in the Knippa Gap have been a topic of major interest among researchers in this area for numerous years, however, the exact location and nature of boundaries are undefined, and the discharge through this area is not accurately known. The input data from this investigation will allow for assessments of discharge, better water budget approximations for the San Antonio pool, and determination of accurate flow boundaries and budgets for Uvalde County. This investigation was limited to the transmissive (karstified) portion of the Edwards aquifer within the study area, and is based on previous studies, and newly collected data. The newly collected data include: 1) compilation of a complete table of wells within the study area; 2) redefined placement of flow boundaries (faults) most of which appear to be structurally controlled; 3) hydrostratigraphic analysis of the Knippa Gap area based on drilling and wireline logs; 4) characterization of the depth of karstification within the Knippa Gap; and 5) analyses of water quality within and contiguous to the study area. These data constrain a revised conceptual model of the flow and karstification in this critical area of recharge to the Edwards aquifer, and provide specific lateral boundaries and vertical karstification zones which can be tested quantitatively. Although current interpretations are tentative, it appears this conceptual model will be readily convertible into a digital model that can test hypotheses relating to water levels and spring discharges.

▼ Paleokarst features are important to understand, both with regards to research geologists and to the petroleum industry. In terms of geology, understanding paleokarst features can yield more information about the depositional and surface environments of past times, and how diagenetic alteration affected the environment during the formation of karst features. In the petroleum industry, paleokarst features can have positive or negative consequence resulting in a potential reservoir with enhanced porosity due to the paleokarst features, or as a geo-hazard to prepare for or avoid when drilling.
Inspired by issues faced when drilling in the Ft. Worth basin, this study utilizes multiple 3-D seismic surveys and subsurface well control to map paleokarsts within the Viola Limestone in the Arkoma Basin. Calculated seismic attribute volumes used to identify paleokarst sinkholes within the Viola Group include coherency and curvature attributes. ImageJ software was used to aid in counting and measuring paleokarst sinkholes identified using seismic mapping, coherency, and curvature attribute volumes. In addition to mapping, a cumulative distribution plot was produced from the diameters of the seismically mapped paleokarst sinkholes, allowing for an estimate to be made as to what the total amount of paleokarst sinkholes are within the study area.
The methods detailed in this study proved to be effective in mapping and analyzing paleokarst sinkholes within the Viola Group. The paleokarst sinkholes mapped were determined to have been formed on the outer edge of the Southern Oklahoma aulacogen, as a result of the Sylvan/Viola unconformity. In addition to this, it has been determined that these paleokarst sinkholes are linked in formation to visually similar paleokarst sinkholes located in the Ellenburger Group in the Fort Worth Basin.

▼ The Late Cretaceous Gulfian series is a prominent and important series across the State of Texas that has been extensively studied since the nineteenth century. It is composed of series of southeast-dipping shelf carbonates and clastics deposited on the northwest margin of the Gulf of Mexico Basin. In south Texas, the Gulfian series was deposited in the Rio Grande Embayment and Maverick Basin and is comprised of the Eagle Ford Group, Austin Group, Anacacho Limestone, San Miguel Formation, Olmos Formation, and Escondido Formation that crop out and continue basinward in the subsurface. Late Cretaceous volcanism formed volcanic mounds composed of altered palagonite tuff that are clustered into two fields, including the Uvalde Field centered in Zavala County. Using the Pedernales 3D seismic survey, located in east-central Zavala County, several volcanic mounds were identified and mapped without the use of well log data by identifying structures and characteristics associated with the volcanic mounds. Isolating these mounds through mapping enabled the mapping of the tops surrounding Gulfian formations, Lower Eagle Ford, Upper Eagle Ford, Austin, Anacacho, and San Miguel, for which time-structure, amplitude, similarity/coherency attribute, and isochron maps were generated. By using 3D seismic data, the volcanic mounds and their relation to surrounding rocks can be better interpreted.

▼ Earth's climate is predominantly controlled by the fluctuation of greenhouse gases, specifically CO2 and CH4, over geologic time. The late Triassic is a period of abrupt climate change that has been associated with a disruption to the global carbon cycle due the emplacement of the Central Atlantic Magmatic Province (CAMP). Evidence has shown that this global carbon cycle perturbation may be the culprit for the end-Triassic extinction. The Whitmore Point Member of the Moenave Formation is a lacustrine deposit with a disputed age of either late Triassic or early Jurassic and currently no absolute dating techniques can be applied to estimate an exact age. Therefore, I propose that identification of the CAMP carbon cycle perturbation through carbon isotope chemostratigraphy of the Whitmore Point Member will be the best current age constraint. δ13Corganic and δ13Ccarbonate were analyzed in the lacustrine deposits of the Whitmore Point Member of the Moenave Formation to construct a carbon isotope chemostratigraphic profile. Carbon isotope evidence indicates that the environmental perturbation caused by the emplacement of the CAMP is present within the Whitmore Point Member. Data was collected at two localities: 1) The Whitmore Point Reference Section (Potter Canyon, Arizona) and 2) Warner Valley, Utah. Carbon isotope data from Potter Canyon reveals a distinctive 5.5 / and 2.75 / decrease in δ13Corganic and δ13Ccarbonate, respectively, in the lower portion of the Whitmore Point Member. Warner Valley does not show a prominent negative carbon isotope excursion but has been correlated to the positive isotope excursion and main negative isotope excursion exhibited within Potter Canyon. Correlation of carbon isotope curves from different localities also helps to regionally correlate the Whitmore Point Member. The identification of the Potter Canyon negative carbon isotope excursion is the first terrestrial record of the CAMP in western Pangea and provides more compelling evidence on the global impacts of the CAMP. Carbon isotope data along with previously published conchostracan data indicates that the end-Triassic extinction is within the lower portion of the Whitmore Point Member while the Triassic - Jurassic boundary is present within the upper portion. Therefore, I propose the age of the Whitmore Point Member to be late Triassic to early Jurassic.

▼ The Atokan Grant Sands are a tight gas sand play that would add new reserves to the Fort Worth Basin. The Fort Worth Basin is located in north-central Texas just west of Dallas, Texas. Within the basin, the study area consists of Denton, Wise, Tarrant, and Parker Counties in Texas. The basin is bounded to the north by the Red River Arch, to the west by the Bend Arch, to the south by the Llano uplift, to the east by the Ouachita structural front, and to the northeast by the Muenster Arch. The Grant Sands are approximately 1,500 ft stratigraphically above their source, the Barnett Shale, and were discovered and mapped from early Barnett vertical drilling. This play evolved from a vertical to a horizontal drilling program with Grant wells being drilled alongside Barnett wells. The purpose of this study is to improve the geologic understanding for enhanced exploration potential.
There is disagreement in the previous studies as to the depositional setting and source areas of the Atoka section of the Fort Worth Basin. This study analyzes core data and regional subsurface mapping to determine an interpretation of the depositional setting of the Grant Sands. A reservoir characterization with a conceptual model for depositional setting will contribute to the current geologic understanding of the Grant Sand Formation to enhance exploration potential.

▼ Arkoma basin is a prolific natural gas basin. The defining feature of this basin is the Atoka Formation that was deposited in the early-middle Pennsylvanian. The Atoka is held equivalent to the tectonic and structural evolution of the basin. This study focuses on one of the many gas fields in the Arkoma Basin in
Arkansas to assess the stratigraphic and structural evolution that the strata in this particular field display.
Aetna Gas Field extends from T. 8N. R. 27 W to T. 9 N, R. 27 W and T. 8 N, R. 26 W to 8N, R. 27. Geographically, Aetna field covers parts of Franklin, Johnson and Logan counties. It is one of the pioneer gas fields in the Arkoma Basin. First discovery of gas in Aetna Field was made in March 1928. The first three producing wells were completed in the upper Carpenter and middle Alma sands of the middle Atoka Formation. An analysis of structures and stratigraphy of the gas field through well log correlations reveal a combination trap for the gas.
Using IHS Petra, stratigraphic correlations were performed on 49 wells in 10 cross sections. The wells selected were sorted by several criteria. Gamma ray logs were given priority. Stratigraphic tops were determined for correlation purposes. The stratigraphic tops were picked and correlated. The middle Atoka Formation was addressed exclusively for the purpose of this study. Structural analysis indicates an arch-and-trough setting that led to gas accumulation in this field. The stratigraphic analysis confirms a thickening to the south following the general southern thickening trend of Atoka Formation in the Arkoma Basin.

▼ Lineaments are mappable, simple or composite linear or curvilinear features of the Earth’s surface longer than one mile, which differ from the patterns of adjacent features and are presumed to reflect subsurface phenomenon such as faults and fractures. The usage of the term refers to the description Lattman published in 1958 and was the foundation for work by MacDonald in 1977, which is the basis for this project. Remote sensing techniques have provided a valuable means to analyze lineaments on a large scale in a relatively short time in comparison to field mapping methods. The products of such fracture studies have been used in exploration for groundwater and may also have implications for other subsurface fluid migration pathways. Cost-benefit evaluations of employing remote sensing techniques have found that this method took less time and saved on costs of drilling. Published work completed by MacDonald included a compilation of lineament maps for 13 counties in Northwest
Arkansas. The maps were published on county highway basemaps and prepared using LANDSAT imagery that was later transferred. Quality of remotely sensed imagery has increased exponentially since the time of the original production and in 2006 the map was digitized by a group of NSF Research Experience for Undergraduate students. Comparison of the digital lineament data to more modern imagery allowed a check on accuracy and extension or modification where appropriate. The final products include a compilation of all relevant literature and data sources related to water quality investigations in mantled karst and fractured rock areas of
Arkansas including the Ozark Dome area and Arkoma basin to the western border and east to the Fall Line. As well as digitization of a lineament map containing the 27 counties based on the most current Digital Elevation Models (DEMs) and satellite imagery available.

▼ In 1950, the U.S. Army Corps of Engineers (USACE) reported a rapid increase of water discharge from the Mississippi River to its distributary channel; the Atchafalaya River. If not prevented by man-made structures, the complete capture of the Mississippi River by the Atchafalaya River was predicted. The USACE report cites multiple causes for the observed increase in discharge partitioning, yet fails to assess the largescale channel dredging operations conducted throughout the Atchafalaya River Basin during the 1930's and 1940's as a potential cause for the increased discharge. To assess the role man-made interventions, specifically channel dredging, played in the increase of discharge partitioning down the Atchafalaya River, this study incorporates a one-dimensional backwater flow model based on conservation of fluid mass and momentum equations and utilizes the geological and engineering data of the Atchafalaya, Mississippi and Old River Systems compiled by the USACE from 1880-1950. Two models were developed from 75 channel cross-sections measured during hydrographic surveys of the Atchafalaya Basin and river systems in 1916-17 and 1950, representing the pre-dredging and post-dredging conditions of the Atchafalaya River. A third model was adapted from the 1916-17 pre-dredging model and incorporates the dredging of a 4 meter deep channel from Morgan City, Louisiana to the headwaters of the Atchafalaya River at Simmesport, Louisiana. Based on this one-dimensional modeling approach, comparison of the 1916-17 Pre-Dredging (16%) and Proposed Dredging (26%) models of discharge partition percentages flowing into the Atchafalaya River from the Mississippi River indicates that dredging is potentially associated with an increase of Atchafalaya River flow partition discharge of +10% under 1916-17 historically measured discharge conditions of 18,000 (m3/s) total discharge above the bifurcation (TDAB). By comparison, the historically measured discharge partition percentages recorded by the USACE for 1916-17 (11%) at 18,000 (m3/s) TDAB and 1950 (22%) at 25,000 (m3/s) TDAB indicate a similar increase in discharge partitioning of +11% change between 1916-17 pre-dredging and 1950 post-dredging conditions. However, due to the limitations of the one-dimensional model to simulate flow through additional downstream bifurcations, further multi-dimensional analysis is needed before definite causation can be warranted.

▼ U-Pb crystallization ages of metamorphic and detrital zircons from all three paragneiss samples fall into the range of ca. 1.85-2.59 Ga, excluding two much older grains. Evidence suggests that the paragneiss of Grollier Lake record deformation exclusively from the Taltson and Trans-Hudson orogenies. It is apparent from geochronological data that the Taltson orogeny played an exceedingly larger role in the deformation of these rocks than the Trans-Hudson. Deposition of the paragneiss protoliths most likely culminated between ca. 2037-1994 Ma with metamorphism ceasing by 1852.1 ± 11.1 Ma. The oldest overgrowth considered to be concordant is 1994 ± 12 Ma and interpreted to represent the first signature of burial facilitated by the Taltson orogeny. U-Pb crystallization ages ranging from ca. 1872-1900 Ma can be attributed to metamorphisms from both the late Taltson or early Trans-Hudson orogenies given that the transition between these events is hard to delineate. Zircons dated > ca. 2.04 Ga are detrital in origin with U-Pb crystallization ages for these grains possibly being discordant as supported by the concordia diagrams. However, these ages can still be explained by provenance from sources such as the ca. 2.17-2.13 Ga Rutledge River basin to the west of Grollier Lake, and the ca. 2.3 Ga Arrowsmith subduction-related plutons north of Lake Athabasca. Older zircons (2955.6 ± 10.7 Ma and 3078 ± 13.9 Ma) in the migmatitic paragneiss are inferred to be inherited from Neoarchean and early Paleoproterozoic crust below. It is possible that rocks of the lower structural levels will record deformation from the Arrowsmith orogeny.

▼ As meandering rivers laterally migrate over time, they build channel belts. The accumulation of all previous flow paths creates the channel belt. To better understand these ancient rivers, modern river systems are being mapped to find statistical relationships between current flow path and the channel belt of river systems. It is important to examine a wide range of systems in terms of age, size, and location. The rivers are being mapped using an ImageJ, interpretations from Saucier (1994) and Google Earth. Three channel belt morphologies are mapped for 15 modern channel belts; the width of the river in relation to the width of the channel belt; the curvature of the meander scars on the channel belt; and the spacing length between unconformable points. Unconformable points are locations where these previous flow paths overlap one another on the channel belt edge. Statistical analysis of the data reveals that the median range for the ratio of channel belt width to mean channel width (W*) is 8.9 to 76, W* for the data set also as a P90/P10 range of 1.6 to 3.7. The median range for the normalized radius of curvature of the channel belt (P*) for the entire data set is 3.8 to 35 and has a P90/P10 range of 16 to 49. The median range for the normalized spacing between unconformable points (
L*) for all river reaches in the data set is 2.7 to 24, with a P90/P10 range of 2.9 to 7.6. These variation constraints provide information about the formation of fluvial channel belts and the petroleum reservoirs they can create.

▼ The Arkoma Basin is a Carboniferous peripheral foreland basin in southeastern Oklahoma and west-central
Arkansas. The formation of the Arkoma Basin is a result of a collision between the North American Plate and the Sabine Terrane. To the north of the basin, there is a structural high that extends southward from the Arkoma Shelf into the basin. This structure is in contrast with the prevailing east-trending strike of structures in the northern margin of the basin and is poorly defined. This paper examined the structure of the salient with stratigraphic and structural cross sections. Across the study area, two NS structural cross sections, three EW cross sections and one EW stratigraphic cross sections were constructed. Strata in the cross sections were divided into three intervals: Morrow I, Atoka I and Atoka II. Analysis of the five structural cross sections certified the existence of the structural high and defined the orientation and magnitude of the structural high. Examination of these three intervals in the stratigraphic cross section revealed no stratigraphic variation in thickness, so the structural high existed after middle Atokan time. The Arkoma Basin subsided at sometime after deposition of the Atoka II unit in northwest
Arkansas.

▼ Wire line logs are widely used in analysis of the subsurface stratigraphy of the middle Atoka Formation, Central Arkoma Basin, Western
Arkansas. SP log, Gamma ray log, resistivity log and conductivity log provide valuable information to construct cross sections.
The middle Atoka formation is composed of a succession of shale and sandstone alternations with thickness reaching approximately 3000 feet in the study area. It contains several sandstone units which include Morris, Tackett, Areci, Bynum, Casey and Dunn”A” separated by shale intervals. The purpose of this study is to identify these units and predict sequence stratigraphy and depositional environment by constructing cross-sections, observing wireline logs and associating previous research. Several isopach maps are made, explaining the development of sandstone in target units such as Tackett and Casey.
The sequence stratigraphy of the middle Atoka formation is mainly composed of transgressive systems tracts and part of a highstands systems tract. The intervals indicate successive sea-level cycles associated transgression and regression from shallow marine to shoreface.
The middle Atoka formation has been proved as a significant exploration target since 1950’s. In order to understand geologic setting and find potential reservoirs within the Arkoma basin, it is vital to comprehend the sequence development and depositional environment of the intervals within the middle Atoka.

▼ The Pennsylvanian Hartshorne Sandstone crops out in an east trending belt across central
Arkansas immediately north of the Ouachita orogenic belt and south of the Boston Mountains. The unit, composed of massive to cross bedded sandstone ranging to 150m in thickness, was deposited by a west-flowing river system that extended from central
Arkansas to southeastern Oklahoma. The source of the sediment has been extensively discussed but not completely established. The object of this thesis is to constrain the source area and terrain based on thin section mineralogy and texture. Thin sections were prepared from outcrops in the Arkoma Basin and were selected from a collection of 45 thin sections for analysis utilizing a petrographic microscope and petrographic analytical techniques.
The Hartshorne Sandstone is composed of quartzose phyllarenite with small amounts amounts of plagioclase and orthoclase feldspar in addition to accessory minerals including zircon, tourmaline and muscovite. Metamorphic rock fragments composed of phyllite dominate the lithic components, schist fragments occur but are rare.
The uplands north of the Arkoma basin are uniformly composed of sandstone composed of quartzarenite interbedded with shale and limestone. Metamorphic rock fragments are rare or absent. Sandstones that compose the Stanley Formation (Mississippian) and the Atoka Formation (Pennsylvanian) of the frontal Ouachita Mountains contain abundant lithic fragments (Atoka) and feldspar (Stanley). The lithic composition of the Stanley and the Atoka is consistent with the lithic composition of the Hartshorne. This suggests that the Hartshorne sediments were sourced from adjacent exposures of the Stanley and Atoka formations south of the Arkoma Basin and that early uplift of the Frontal Ouachitas were instrumental in confining the Hartshorne River system to a westward direction across the incipient Arkoma Basin early in Pennsylvanian time.

▼ Paleozoic formations in western
Arkansas have been well-studied; however, they are not well-understood in the eastern part of the state. The study area encompasses Townships 9. N. and 10. N., Ranges 6. W. and 7. W. in north-central White County,
Arkansas. This area is at the intersection of four physiographic provinces as defined by the
Arkansas Geologic Survey- the Ozark Plateaus, the
Arkansas River Valley, the Ouachita Mountains, and the Mississippi Alluvial Plain. Interpretations of the surface unit in the area disagree. The
Arkansas Geologic Map shows that the Morrowan Hale Formation crops out in the area; however, various petroleum geologists suggest that the surface unit in the area is of the Atoka Formation. Several wells in the area have produced natural gas from the sandstones in question, meriting further investigation of the units' potential source.
Petrographic analysis of 17 thin sections prepared from sidewall cores taken from three wells in the study area, correlation of 141 wireline logs, and construction of cross sections, gross sand isopachs, and structure maps were used to develop a stratigraphic framework of the area. These analyses imply that the subject units are likely of the Hale Formation and have multiple sources including the Ouachita Mountains, the Appalachian Mountains, the Ozark Dome, and the North American cratonic interior. Additionally, the sandstones were likely deposited in a transitional near-shore marine environment with a fluvial-deltaic influence.
