The Guangshigou deposit is the largest pegmatite-type uranium in Shangdan domain of North Qinling Orogenic Belt, which characterized by enrichment uraninite hosted biotite granitic pegmatites. At Guangshigou, commonly occurs as mineral inclusions quartz, K-feldspar and or interstices these rock-forming minerals with magmatic characteristics (e.g., U/Th < 100, high ThO2, Y2O3 REE2O3 contents ...
The calculation of a reliable temperature dependent dolomite solubility product constant (Ksp?dol) has been the subject much research over last 70 years. This study evaluates log10(aCa2+/aMg2+) values using PHREEQC (Pitzer approach) for screened subset (n = 11,480) formation waters in U.S. Geological Survey National Produced Wate...
We investigate an outcrop of 187 Ma lacustrine pillow basalts of the Talcott Formation exposed in Meriden, Connecticut, USA, focusing on coordinated analyses of one pillow lava to characterize the aqueous history of these basalts in the Hartford Basin. This work uses a suite of multidisciplinary measurements, including hyperspectral imaging, other spectroscopic techniques, and chemical and mine...
