Culprite is an oxide mineral composed of copper oxide Cu2O, and is a minor ore of copper. It is a secondary mineral which forms in the oxidized zone of copper sulfide deposits. It frequently occurs in association with native copper, azurite, chrysocolla, malachite and a variety of iron oxideminerals. Culprite was first described in 1845 and the name derives from the Latin cuprum for its copper content. Culprite is found in the Ural Mountains, Altai Mountains, Sardinia, France, Arizona, Chile, Bolivia, and Namibia.
