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.

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

The Texas Coastal Zone is marked by diversity in geography, resources, climate, and industry.

Aquifers in the Houston-Galveston area are composed principally of fluvial-deltaic sediments. The Alta Loma Sand is a complexly faulted, high-sand-percent unit that represents a seaward progression of fluvial, delta-plain, and delta-front facies.

The land surface in the Texas Coastal Zone is interlaced with active and potentially active surface faults. They are subtle features which are difficult to identify until they have caused damage to manmade structures. To date (1978), significant damage has resulted.

The Catahoula Formation of the Texas Gulf Coastal Plain consists of two depositional systems--the Gueydan bedload fluvial system of the Rio Grande embayment and the Chita-Corrigan mixed load fluvial system of the Houston embayment.

The Oakville Sandstone is a major aquifer and a major host of uranium deposits in the Texas Coastal Plain.

The Oakville Formation consists of sediments deposited by several major fluvial systems that traversed the Texas Coastal Plain during the Miocene Epoch.
