  • Paramontroseite - Wikipedia

    en.wikipedia.org/wiki/Paramontroseite The montroseite, VO(OH), is deposited in crystalline masses in a sandstone matrix by some unknown process. Usually iron occurs in place of some of the vanadium. Oxygen in the air or groundwater then oxidizes the crystallised montroseite at temperatures under 50 °C through the reaction: 2VO(OH) + 1 ⁄ 2 O 2 → 2VO 2 + H 2 O
