The Davis Mountains, located in the Trans-Pecos region of Texas, are comprised of Tertiary volcanics and associated volcaniclastic facies of the McCutcheon Series. The study area covers approximately 3200 square miles and ...
Three-dimensional quantitative textural analysis of metamorphic rocks using high-resolution computed X-ray tomography : methods, techniques and application to natural samples
Quantitative three-dimensional textural analysis of metamorphic rocks using high-resolution computed X-ray tomography and automated image mensuration produces data on the size and position of thousands of crystals in a ...
Mobile sediments in a karst aquifer
In karst aquifers, mobile sediments may play a fundamental role in determining water quality by concentrating and transporting contaminants. This study investigates spatial characteristics of sediment in a karst aquifer, ...
Sedimentary processes controlling halite deposition, Permian Basin, Texas
Evaporites preserve considerable information about their depositional and diagenetic history. The facies and geochemistry of two exceptionally well-preserved evaporite sections within the Permian Basin the Guadalupian to ...
Hydrogeology of the lower Cretaceous Edwards and Trinity Group formations near Junction (Kimble County) Texas
This study describes ground-water flow in the Lower Cretaceous formations near Junction (Kimble County), Texas. Rock exposures were examined throughout the 150-mile study area to determine the nature and distribution of ...
