BRISSON AND JALEIGH Q. PIER Geosciences & Ecology and Evolutionary Biology, University of Connecticut, Storrs, CT 06269 INTRODUCTION Earth-system perturbations caused a series of mass extinction events during the Devonian Period, including the Taghanic event in the Givetian, the Lower and Upper Kellwasser events in the Frasnian, and the Hangenberg event in the Famennian (House, 2002; Bambach, 2006). These extinctions occurred against the backdrop of orbitally forced sea-level fluctuations, the Acadian Orogeny (Averbuch et al., 2005), the expansion of plants and animals on land (Algeo et al., 1995), and ecological changes in the marine biosphere (Signor and Brett, 1984; Bambach, 1999). The Frasnian-Famennian boundary in particular represents a significant global crisis, considered one of the “big five” mass extinctions (Raup and Sepkoski, 1982) that led to the demise of the widespread and diverse Devonian -

ABSTRACT OF THESIS STRUCTURAL GEOLOGY OF THE TRANSYLVANIA FAULT ZONE IN BEDFORD COUNTY, PENNSYLVANIA Transverse zones cross strike of thrust-belt structures as large-scale alignments of cross-strike structures. The Transylvania fault zone is a set of discontinuous right-lateral transverse faults striking at about 270º across Appalachian thrust-belt structures along 40º N latitude in Pennsylvania. Near Everett, Pennsylvania, the Breezewood fault terminates with the Ashcom thrust fault. The Everett Gap fault terminates westward with the Hartley thrust fault. Farther west, the Bedford fault extends westward to terminate against the Wills Mountain thrust fault. The rocks, deformed during the Alleghanian orogeny, are semi-independently deformed on opposite sides of the transverse fault, indicating fault movement during folding and thrusting. Palinspastic restorations of cross sections on either side of the fault zone are used to compare transverse fault displacement. -

Assessing the Petroleum Geology and Future Development of the Clendenin Gas Field in Kanawha County, West Virginia
Assessing the Petroleum Geology and Future Development of the Clendenin Gas Field in Kanawha County, West Virginia By: Jonathan Prevatte August 2020 Director of Thesis: Donald W. Neal Major Department: Geological Sciences Petroleum is one of the main sources for energy production in the US and is therefore important for the continuation of economic growth. Future development of petroleum resources in the US to meet supply demands is equally important. Understanding the controls on petroleum production will help in determining where and how to development these resources for maximum production. West Virginia is home to many gas fields and is underlain by one of the more prominent gas producing shales, the Marcellus Shale. The Clendenin Gas Field in Kanawha County is one of the historical gas producing areas found in West Virginia. This assessment is focused on the Devonian strata throughout the field including the Marcellus Shale. Using available geophysical logs, production data, and historic well records obtained from the West Virginia Geologic and Economic Survey (WVGES), cross-sections, isopach maps, and structure contour maps were created to give a visual representation of the subsurface geology across the field. Construction of the cross-sections and maps in conjunction with production and well record data aided in the identification of controls influencing production throughout the field. Applying the findings of this assessment to future production may reduce costs and improve yields of future petroleum wells. Results of this study indicate several options should be considered when planning for future production wells within the field. Target areas include the areas to the east of the field where formations tend to thicken. -
