Navajoite is a vanadate mineral, a vanadium oxide, with formula V2O5·3H2O. It is a hydrated mineral form of vanadium pentoxide.
The type specimen was discovered in a mine in Monument Valley (36° 59′ N, 110° 6′ W), Arizona, USA, in 1954.[1][2] Navajoite has also been found in other areas of the Colorado Plateau, and at Potash Sulphur Springs (34° 28′ 30″ N, 92° 57′ 48″ W), near the Hot Springs National Park in Arkansas.[2]
Navajoite is named after the Navajo Indian Nation, on whose territory the first specimen was found.[1]
