Vanuralite

Vanuralite

An allusion to its components, Vanuralite is named for vanadium (van), uranium (ur), and aluminum (al). Vanuralite is found in only one country in the world at the Mounana mine, its type locality, and the Oklo mine in Gabon. It occurs at both of these mines in the oxidized zones of a uranium-vanadium deposit that is also lead-bearing. Vanuralite is radioactive.
