The Texas Panhandle traditionally has been an important source of mineral resources, especially petroleum, and resources will continue to contribute heavily to the economy of the area. The seven cross sections of this report synthesize the subsurface geology of the region.

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.

These cross sections numerically correspond to previously published onshore cross sections (CS0002--Dodge and Posey, 1981) and extend those sections across the continental shelf into the Miocene, a recent target of renewed petroleum exploration.

The Palo Duro Basin of the Texas Panhandle and eastern New Mexico contains bedded Permian salts of sufficient thickness and depth for the basin to be considered as a potential site for long-term storage and isolation of high-level nuclear waste.

These cross sections illustrate the regional structure and stratigraphy beneath the Texas continental shelf .

This cross section set traverses four Cenozoic depositional sub-provinces: the Rio Grande Embayment, San Marcos Arch, Houston Embayment, and Sabine Arch.

Six interlocking regional stratigraphic cross sections of Lower Cretaceous strata (middle Albian-lower Cenomanian) of the Edwards and Stockton Plateaus of West Texas illustrate the vertical and lateral extent of lithostratigraphic units and distribution of facies and facies tracts.

Written in an informal style for a nontechnical audience, this guide summarizes geologic features and history of McKinney Falls State Park, just south of Austin, Texas.
