The hydrochemical history of ground water in the arid southeastern Hueco Bolson and southwestern Diablo Plateau was investigated by collecting soil-moisture samples from unsaturated siliciclastic bolson-fill sediments and groundwater samples from the Diablo Plateau aquifer, the Hueco Bolson silt

Sixteen depositional sequences, commonly called cyclothems, each composed mostly of limestone(retrogradational/transgressive) and siliciclastic (progradational/regressive) subsequences, or systems tracts, record the paleogeography during Late Pennsylvanian (Virgilian Epoch) and Early Permian (Wol

This field guide summarizes recent interpretations of the upper Cenozoic stratigraphy of parts of the Southern High Plains and Rolling Plains in northwestern Texas and eastern New Mexico.

This guidebook, Hydrogeology of Trans-Pecos Texas, grew out of our interest in the hydrogeology of desert environments.

Organic petrological, organic geochemical, and chemical analyses of Tertiary (Paleocene to Eocene) coals (to a 2,000-ft [610-m] depth) from the Wilcox, Claiborne, and Jackson Groups of Texas reveal characteristic properties of these coals.

The purposes of this study were (1) to quantify recent (1974 to 1982) movement of Texas shorelines and vegetation lines by analysis of aerial photographs; (2) to place this movement in historical (pre-1974) context; and (3) to examine the influence of environmental variables such as storms, sea l

Detailed characterization of the spatial distribution of hydraulic conductivity (K) by direct measurement is usually impractical.

Along the Texas Gulf shoreline and offshore, the distal margin of the Frio Formation is a deep hydrocarbon province that is underexplored relative to the onshore Frio.
