Geochemical evolution of ground water in the Barton Springs segment of the Edwards Aquifer
The water quality in a karst (limestone) aquifer changes over time, making the application of traditional hydrogeologic principles difficult or impossible. This research's goal was to advance the understanding of the ...
Sequence stratigraphic framework and systems tracts analysis of Lower Miocene shelfal clastic deposits : Redfish Bay area, Texas Gulf Coast
The deposits of the Lower Miocene section of the Redfish Bay area along the Texas Gulf Coast were characterized and their systems tracts and depositional environments were interpreted. A three-dimensional seismic volume ...
Hillslope seepage erosion, spring sapping, and knickpoint migration : evidence of groundwater sapping Middle Trinity Aquifer, Honey Creek Basin, Comal County, Texas
Geomorphic features within Honey Creek basin are consistent with formation by spring sapping which is the erosion of soil and rock by groundwater. Geomorphic evidence includes: swallow holes (stream swallets) that pirate ...
Nature and source of mineralizing fluids at the Presidio mine, Shafter district, Presidio County, Texas
The object of this research is to determine the nature and source of the mineralizing fluids that formed the Presidio Zn-Pb-Ag deposit, and to determine the relationship of the Presidio deposit to the rest of the Shafter ...
The hydrologic function of small sinkholes in the Edwards Aquifer recharge zone
Thin soils on Cretaceous karst bedrock typify the Edwards aquifer recharge zone in central and south Texas U.S.A. Most of the recharge occurs in major streambeds in this region, but abundant evidence of active karstic ...
Modeling reflux dolomitization
The process of reflux dolomitization is commonly invoked to explain dolostone occurrence and distribution. The time required for this process to take place is not well understood. Volumetric flow rates are the dominant ...
