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

Damon Mound salt dome, located in Brazoria County, Texas, is a shallow diaper that has salt less than 600 ft (180 m) and cap rock less than 100 ft (30 m) below the surface.

The State-owned submerged lands of Texas encompass almost 6,000 mi2 (15,540 km2). They lie below waters of the bay-estuary-lagoon system and the Gulf of Mexico and extend 10.3 mi (16.6 km) seaward from the Gulf shoreline (fig. 1).

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

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 In 1976, approximately 6,000 acre-ft of ground water were withdrawn from the Oakville for municipal use.

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

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.

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