Paramendozavilite

Paramendozavilite

Named after the Greek word para, meaning “near”, and for its chemical similarities to mendozavilite. Paramendozavilite is a rare mineral found only at its type locality at the Cumobabi molybdenum deposit in Sonora, Mexico and in a newer locality in the United States. It occurs at its type locality in oxidized molybdenum-rich pegmatitic breccias within a granodiorite.
