An Integrated Well Log and 3D Seismic Interpretation of Missourian Clinoforms, Osage County, Oklahoma
… within a depositional context. Shelf-prism and subaqueous, delta-scale clinoforms of Missourian age observed in 3D seismic were interpreted with greater sequence stratigraphic detail when coupled with wireline well logs. The Late Pennsylvanian Midcontinent Sea was thought to be approximately 150 …

Aridification of the Indian subcontinent during the Holocene : implications for landscape evolution, sedimentation, carbon cycle, and human civilizations
… second site, a seismic survey of the Indus River subaqueous delta describes the morphology and Holocene sedimentation of the Pakistani shelf and identified suitable coring locations for paleoclimate reconstructions. The δ13Cwax record shows a stable arid climate over the dry regions of the Indus …

Aridification of the Indian subcontinent during the Holocene : implications for landscape evolution, sedimentation, carbon cycle, and human civilizations
… isotopes of terrestrial plant leaf waxes ([delta]¹³Cwax) preserved in sediment provide integrated and regionally extensive records of flora for both sites. For the Godavari River basin the ([delta]¹³Cwax record shows a gradual increase in aridity-adapted vegetation from ~4,000 until 1,700 …

Paleontology and Paleoecology of the Nada Member of the Borden Formation (Lower Mississippian) in Eastern Kentucky
… (Mississippian) in northeastern Kentucky was the delta platform deposit of the Borden delta. It consists mainly of iliciclastic mudstones with carbonates and siltstone interbeds. The dominant fossil groups that it contains are crinoids, brachiopods, rugose corals, and bryozoans. Biostratigraphic …

Anatomy of a Carboniferous transgression: upper Tullig Cyclothem, County Clare, Ireland
… 3) the paleoenvironmental transition from fluvio-deltaic to open marine conditions, and how this ties in to the overall evolution of the Western Irish Namurian Basin. These aims have been achieved by examination of all the outcrops of the transgressive upper Tullig cyclothem in County Clare, which …

Developing Recognition Criteria for Current-Wave-Enhanced Sediment Gravity Flows
… frequently observed in modern settings, muddy prodeltaic deposits are rarely identified in the rock record, in part because no catalogue of easily distinguishable recognition criteria exists for this class of mudstones. In order to help overcome this deficiency, this dissertation project employs a …
