The state of Texas is rich in natural resources. However, these resources are not located in all parts of the state, but rather localized in regions of the state. Quarrying and production operations are located within these area based on geologic formations and the quality of materials for specific uses. These operations are located in these areas to control transportation import costs and maintain continued economic growth. The accompanying map provides an overview of these statewide operations.

Clay Products Industry

The state of Texas contains an abundance of varied clay resources that provide a great boost to our state’s economy. These clay resources occur in many geologic units. Production includes ball clay, bentonite, common clay and shale, fire clay, fuller’s earth and kaolin. The mining and production of useful products supplies so much of the materials critical to our nation and state’s infrastructure. Texas is the fourth largest producer of clay and aggregates in the United States.
