Upper Jurassic microbolite buildups in the little cedar creek and Brooklyn fields in SW Alabama
(Wichita State University, 2014-05)This study investigates the stratal relationships of a pure microbolite within the Upper Jurassic strata at the Little Cedar Creek, and Brooklyn Fields, or complex, for the development of a refined exploration model of ... -
Upper Jurassic thrombolite reservoir play, northeastern Gulf of Mexico
(The American Association of Petroleum Geologists, 2004-11)In the northeastern Gulf of Mexico, Upper Jurassic Smackover inner ramp, shallow-water thrombolite buildups developed on paleotopographic features in the eastern part of the Mississippi Interior Salt basin and in the Manila ... -
Using chromate to investigate the impact of mineral-organic contact time on the surface reactivity of goethite
(Royal Society of Chemistry, 2018-10-01)Chromate was used as a chemical probe to investigate the impact of mineral-organic contact time on the surface reactivity of two different sizes of goethite particles. A series of goethite-chromate sorption batch reactions ... -
Using chromate to investigate the impact of natural organics on the surface reactivity of nanoparticulate magnetite
(American Chemical Society, 2015-02-17)Chromate was used as a chemical probe to investigate the size-dependent influence of organics on nanoparticle surface reactivity. Magnetitechromate sorption experiments were conducted with similar to 90 and similar to 6 ... -
Using energy dispersive X-ray fluorescence (ED-XRF) to assess the stratigraphic relationships of the middle Jurassic Gypsum Spring and Piper formations, Bighorn Basin, Wyoming and Montana
(Wichita State University, 2015-05)Chemostratigraphy via X-ray fluorescence measures the shifts in elemental properties within a given section of strata. It has proven to be a successful tool in both correlation and paleo-environment reconstruction. Recently, ... -
Vegetation responses along environmental gradients on the Ordos plateau, China
(Springer Verlag, 2006-04)The Ordos plateau is a unique ecotone and is a focal region for the campaign to reduce or reverse desertification in China. This paper explores the relationship between vegetation and environmental gradients on the Ordos ...
