The Miocene Oakville Sandstone is a major aquifer and uranium host beneath the Texas Coastal Plain. In 1976, approximately 6,000 acre-ft of ground water were withdrawn from the Oakville for municipal use. An additional but unknown amount was used for drinking water in rural areas, for livestock, and for irrigation.

The Bureau of Economic Geology—this bureaucratic title belies the essence of this organization: an ongoing group of professionals with a definite personality.

The publication comprises 24 structural dip cross sections, spaced 15 to 20 mi apart along the Texas coast, and 4 structural strike cross sections. Dip sections extend from near the Wilcox outcrop to the coastline.

Regional cross sections of Middle and Upper Permian rocks in the Texas Panhandle illustrate the lithology, depositional systems, and structure of these salt-bearing strata.

Jurassic, Cretaceous, and Tertiary sediments in the East Texas Basin have been structurally modified by movement of Middle Jurassic Louann Salt. Important structural elements in the basin include salt diapirs, deep salt anticlines and turtle-structure anticlines as well as prominent fault systems.
