First Use of Arkansas Novaculite


Native Americans were the first people to mine the Arkansas Novaculite Formation. They noticed its conchoidal fracture and discovered that it could be knapped – just like flint – into projectile points, scrapers, and cutting tools. They mined novaculite, used it to manufacture cutting tools and weapons, and traded the material and products over a broad area. The Quapaw, Osage, Caddo, Tunica, Chickasaw, and Natchez tribes were especially involved in the mining.

Novaculite ridges
ovaculite ridges: Ridges of the Caballos Novaculite in the Lightning Hills of Brewster County, Texas. The Lightning overthrust crops out in the valley between the ridges. In the subsurface, the Caballos novaculite yields oil and gas from a tripolitic zone near the top of the rock unit and from fracture porosity in the lower portion of the rock unit.

Prehistoric people in other parts of the world have worked novaculite deposits to manufacture weapons and cutting tools. Novaculite and manufactured products from these areas were transported and traded across great distances.
