Description

Arkansas Bauxite – Historic Aluminum Ore from the Southern United States

This Arkansas bauxite specimen represents one of the most important aluminum ore deposits in North America. Known for its earthy reds, browns, and warm orange tones, Arkansas bauxite forms through intense weathering of aluminum-rich host rock, creating a dense, nodular material prized by collectors, educators, and geology enthusiasts.

About Arkansas Bauxite

Arkansas is home to some of the most historically significant bauxite deposits in the United States. The region’s ore formed through prolonged chemical weathering in a subtropical environment, producing aluminum-rich minerals such as gibbsite, boehmite, and diaspore. These deposits supplied a major portion of U.S. aluminum production throughout the 20th century, especially during World War II.

Collectors value Arkansas bauxite for its distinctive textures, color variations, and geological importance. Many specimens display pisolitic or nodular structures—rounded, pea-sized concretions that reveal the unique conditions under which the ore formed.

• Distinctive Appearance: Natural red, brown, and orange tones with classic pisolitic textures
• Educational Value: Excellent for teaching mineral formation, weathering processes, and ore geology
• Collector Appeal: Increasingly scarce as historic mining areas are no longer accessible
