Pre-drill Groundwater Geochemistry in the Karoo Basin, South Africa.
Enhanced production of unconventional hydrocarbons in the United States has driven interest in natural gas development globally, but simultaneously raised concerns regarding water quantity and quality impacts associated with hydrocarbon extraction. We conducted a pre-development assessment of groundwater geochemistry in the critically water-restricted Karoo Basin, South Africa. Twenty-two sprin...
متن کاملSulfur geochemistry across a terrestrial Permian^Triassic boundary section in the Karoo Basin, South Africa
Concentrations of sulfur and carbon, and isotopic compositions of sulfur were determined in sedimentary rocks from a section across the terrestrial Permian^Triassic (P^Tr) boundary in the northern Karoo Basin, South Africa. High concentrations of sulfide produced by sulfate-reducing bacteria were found in the sedimentary rocks at and just below the perceived P^Tr boundary. The ratios of organic...
متن کاملPetrography and element geochemistry of dolomites of Sibzar Formation, east of Neyshabur
The Sibzar Formation (Middle Devonian) is located about 30 km east of Neyshabur and is composed of lower dolostone with intercalations of sandstone, middle basaltic sill and upper dolostone to limy dolostone, with a thickness of 334 m. Based on the crystal size in this formation, three different types of dolomite (D1, D2, Vd) were identified and according to the textural classification of the d...
متن کاملDepartment of Mineralogy , Petrography and Geochemistry
Department of Mineralogy, Petrography and Geochemistry is the oldest Earth science department at the AGH University of Science and Technology. It was created in 1919 as one of the first six departments of the Academy of Mining and was initially named as the Department of Mineralogy and Petrography. The Department was organized by Professor Józef Morozewicz (1865–1941) who chaired the Organizing...
متن کاملGeochemistry and petrography of impact breccias and target rocks from the 145 Ma Morokweng impact structure, South Africa
Morokweng is a large, 145 Ma impact structure in the Northwest Province of South Africa. The impact origin of this structure and its melt rock has been confirmed by ample evidence of shock metamorphism in clasts within the melt rock and samples from granitoid basement below the melt body. The age of this structure is indistinguishable from the biostratigraphic age of the Jurassic-Cretaceous (J-...
