Primary sedimentary structures in modern point-bar deposits of the Amite River in Louisiana and the Colorado River in Texas are analogous to features observed in Eocene Simsboro and Pleistocene Colorado River deposits of the Texas Gulf Coastal Plain.

Sulfur, along with salt, coal, and limestone, is one of the basic raw materials of the chemical industry. A nation’s per capita sulfur consumption is a reliable index to its chemical production and a rough index to its standard of living.

This report deals with the occurrence and potential production of industrial sand in the Gulf Coast area of Texas. The study area covers approximately 23,000 square miles underlain by alluvial, deltaic, beach, and eolian deposits of Pleistocene and Recent age.

The uranium industry, born in boom in the late 1940's and early 1950's, fell upon hard times after about a decade of lusty growth as anticipated private markets failed to develop on schedule and the United States Atomic Energy Commission cut back and stretched out its purchase program.

Regional investigation of the lower part of the Wilcox Group in Texas in outcrop and subsurface indicates seven principal depositional systems. These include: (1) Mt.

Limestone is one of the most important nonfuel mineral resources in Texas. Annual production exceeds $30 million; value added in the manufacture of such products as cement and lime amounts to about $100 million annually.

When a reference is made to the mineral resources of Texas, most people think of oil and gas, and some few also of sulfur. And, of course, it is true that of the whopping $4.4 billion dollars’ worth of minerals produced in Texas in 1963, 92% was oil, gas, and natural gas liquids.

Since the days of R. T. Hill (1901) two Upper Cretaceous lithic units have been used as formations but have remained unnamed.

Minerals play a vital role in the economy of an industrial State. In Texas, where annual production of minerals currently amounts to more than $4.
