* Petroleum and Natural Gas: The region is a major oil and gas producing area.
* Coal: Significant coal deposits are found in the Ouachita Mountains.
* Limestone: Used for construction, cement production, and agriculture.
* Sandstone: Used for building materials and landscaping.
* Granite: A durable stone used in construction and monuments.
* Quartz: Used in electronics, glassmaking, and other industries.
