Stratigraphic And Structural Analysis Of Middle Atoka Formation In Aetna Gas Field, Franklin, Johnson And Logan Counties, Arkansas, Ikramuddin Bahram

Graduate Theses and Dissertations

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 …

Long-Term Effects Of Alternative Residue Management Practices On Near-Surface Soil Properties And Soybean Production In A Wheat-Soybean, Double-Crop System In Eastern Arkansas, Christopher Ryan Norman

Graduate Theses and Dissertations

Adoption of management practices that maintain or increase soil organic matter (SOM), which contains 58% carbon (C) on average, may help to mitigate climate change by sequestering atmospheric C. Therefore, the main objective of this study was to determine the long-term trends in SOM, soil C and nitrogen (N), bulk density, various soil chemical properties (i.e., pH, electrical conductivity [EC], and Mehlich-3-extractable nutrients) in the top 10 cm, and soybean yield as affected by residue burning (burning and non-burning), tillage (conventional and no-tillage), irrigation (irrigated and non-irrigated), and N-fertilization/residue level (high and low) in a wheat (Triticum aestivum L.)-soybean [Glycine …

Stratigraphic Analysis With Respect To Aggregate Potential In The Duffield Quarry In Gum Log, Arkansas, Brock Evan Langford

Graduate Theses and Dissertations

The crushed stone mining industry is valued at nearly one billion dollars in Arkansas alone. Physical properties of the rock dictate whether or not an area may be suited for the establishment of an aggregate quarry. The Gum Log quarry located 10 miles northeast of Russellville, Arkansas is geographically well situated near areas in need of aggregate material, as well as physically competent rock. The rock mined in Gum Log is located in the Upper Atoka Formation, a Middle Pennsylvanian aged member of the Arkoma Basin. There are five different lithologic facies identifiable in the quarry (Facies 1-5 respectively): A …

Petrology And Weathering Environment Of Sub-Unconformity Limestone Unit: The Kessler Limestone Member Of The Bloyd Formation, Morrowan (Pennsylvanian) Northwest Arkansas, Thomas Daniels Dolan

Graduate Theses and Dissertations

In northwest Arkansas the thin, widespread Pennsylvanian Kessler Limestone of the Bloyd Formation is exposed in numerous locations. Comparison of various exposures shows the Kessler is heterogeneous in thickness and lithology. Thickening of the Kessler occurs southward into the Arkoma Basin where the interval has been commonly used as a horizon for natural gas exploration. The Kessler Limestone is underlain by the Dye Shale Member of the Bloyd Formation and overlain by the Trace Creek Shale of the Atoka Formation. The contact between the Kessler Limestone Member and the Trace Creek is a regional unconformity in the midcontinent, marked by …

Toolstone Use In Ozark Prehistory: Assessing Adaptations To A Lithic Dichotomy In The Boston Mountains And Springfield Plateau, Luke Allen Morris

Graduate Theses and Dissertations

Toolstone use in the Ozark Mountains is a reactionary process reliant on how the landscape provides or constrains chipped stone for prehistoric populations. These technological adaptations are recognized at sites throughout the area, but no regional assessment of lithic assemblages provides answers as to why certain stones are used at a particular location. This thesis employs a five step mass analysis of lithic assemblages, and GIS visualizations to observe how the organization of stone technologies vary based on location within contrasting geologic contexts. The chert-bearing Springfield Plateau, and the Boston Mountains with siltstone, are two neighboring dichotomous landscapes that illustrate …

Wayne E. Sabbe Arkansas Soil Fertility Studies 2014, Nathan A. Slaton

Arkansas Agricultural Experiment Station Research Series

Rapid technological changes in crop management and production require that the research efforts be presented in an expeditious manner. The contributions of soil fertility and fertilizers are major production factors in all Arkansas crops. The studies described within will allow producers to compare their practices with the university’s research efforts. Additionally, soil-test data and fertilizer sales are presented to allow comparisons among years, crops, and other areas within Arkansas.
