Characterization of Devonian Black Shale Depositional Environments and Diagenetic/catagenetic Processes Using Nitrogen Isotopes and Other Geochemical Proxies: Ohio Shale, Eastern Kentucky
Otto, Brice Aaron (2015-07-01)Research investigating catagenetic alterations of ?15Nbulk values in Devonian shales have shown little correlation between ?15Nbulk profiles and thermal maturities; instead it was concluded that ?15Nbulk values primarily ... -
Chemical and Isotopic Analysis of Hot Springs in Zambia; No Evidence for near Surface Rift-related Magmatic Body
Niles, Mary Catherine (Oklahoma State University, 2014-12-01)Zambia exhibits extensive geothermal activity in an amagmatic rift zone. Current models for rift initiation suggest magma plays an important role in softening the lithosphere, allowing extension. In Zambia, lack of surface ... -
Chemical and Isotopic Evolution of Dissolved Inorganic Carbon in Groundwater of the Okavango Delta, Botswana
Akondi Nkerh, Rawlings (Oklahoma State University, 2014-05-01)This paper reports the results of a study of the origin and the chemical and isotopic evolution of dissolved inorganic carbon (DIC) in groundwater in the Okavango Delta in semi-arid Botswana. The Okavango Delta is one of ... -
Geologic Controls on Nitrogen Isotopes in Marine Black Shale: a Case Study of the Woodford Shale, Anadarko Basin, Oklahoma
Rivera, Keith Thomas (Oklahoma State University, 2013-12-01)Determining depositional environments of organic-rich black shale can enhance the identification of hydrocarbon producing intervals. Several methods have been utilized to identify depositional environments; however, for ... -
Investigating the Processes That Control Water Chemistry During Refilling of Lake Ngami in Semiarid Northwest Botswana
Meier, Scott David (Oklahoma State University, 2014-05-01)Lake Ngami is an endorheic lake in the distal portion of the Okavango Delta in semiarid Botswana. The lake was dry until 2009 when it began filling with water. The physical, chemical, and stable isotopic composition of the ... -
Marine Nitrogen Cycle Across the Cretaceous-paleogene Boundary at Maud Rise
Beckwith, Bradley (2016-07-01)The marine nitrogen cycle across the Cretaceous-Paleogene (K-Pg) boundary at Maud Rise provides insight into an important environmental variable during the K-Pg extinction event, the redox state of the water column. This ...
