Limestone

Limestone represents one of the most widely available of the mineral resources of Oklahoma, and has generally accounted for around sixty percent of the reported tonnage of all non-fuel minerals mined in the state.

Three major production areas exist within Oklahoma; the Tulsa-Rogers-Mayes County region of northeastern Oklahoma north of the Arkansas River, the Arbuckle Mountains region of Murray County and extending into Pontotoc County, and the Wichita Mountains area of Comanche and Kiowa Counties. Approximately 450 million tons of limestone have been mined in Oklahoma in the last quarter century.

Limestone is used mainly in the crushed state as concrete aggregate for building highways and other structures, railroad ballast, glass manufacturing, cement production, preparation of lime and agricultural purposes. Some limestone is used as dimensional building stone.
