Shcherbinaite is a vanadate mineral, a vanadium oxide, with formula V2O5. It is the mineral form of vanadium pentoxide.
The type specimen was discovered at an andesine dome on the Bezymianny ("nameless") volcano (55° 58′ 42″ N, 160° 35′ 12″ E) in Kamchatka in the Russian Far East, and the discovery was validated by the IMA in 1972.[1][2] It has also been found at the nearby Tolbachik volcano (55° 49′ 48″ N, 160° 19′ 48″ E), and at the Izalco volcano (13° 48′ 47″ N, 89° 37′ 59″ W) in El Salvador:[2] in all cases, it is associated with fumarole activity.[4]
Shcherbinaite is named after the Russian geochemist Vladimir V. Shcherbina (1907–78).[1]
