Salt dissolution has affected parts of the Upper Permian Salado, Seven Rivers, San Andres, Glorieta, and upper Clear Fork Formations beneath the Pecos River valley in eastern New Mexico and has been active beneath the Canadian River valley and the Rolling Plains of the Texas Panhandle.

This folded transparent map is at the same scale as its corresponding Geologic Atlas of Texas (GAT) sheet and can be superimposed on it to compare gravity information with surface geology.

Although plots of pressure versus depth are useful for understanding the hydrodynamics of ground-water systems, they can be difficult to interpret.

Large areas of offshore Texas remain unexplored even though sedimentary facies and structural traps favor the generation and accumulation of hydrocarbons.

One nonconventional target for increased oil recovery in Texas is oil that remains in abandoned reservoirs, defined as reservoirs that produced no oil or gas in 1977 and 1982.

Bedded salt of the Permian San Andres Formation, Palo Duro Basin, Texas, is under consideration for the isolation of high-level nuclear waste.

Data collected during the last 5 years on the 15 shallow salt diapirs that extend upward to shallow depths (<4,000 ft, 1,220 m) in the East Texas Basin are presented here in graphical and tabular form.

The Edwards Formation, on the downthrown side of Mt. Bonnell fault in the Austin, Texas, area (Hays and Travis Counties), is part of the northeastern extension of the Edwards Underground Reservoir, the primary source of water in numerous counties along the Balcones Fault Zone.
