Legrandite

Zn2AsO4(OH)·H2O
Monoclinic heart IMA grandfathered

Legrandite is a hydrated zinc arsenate mineral with the chemical formula Zn2AsO4(OH)·H2O. It crystallizes in the monoclinic crystal system and is classified under the Strunz classification as 8.DC.10. The mineral exhibits a white streak and typically displays a vitreous to pearly luster. It is relatively soft, with a hardness that is not explicitly stated, and has a moderate density. Legrandite is known for its distinctive color, which can range from yellow to greenish or brownish hues. It belongs to the group of nesosilicates, though its composition is primarily based on arsenate rather than silicate. The mineral is typically found in oxidized zones of zinc-arsenic-rich ore deposits.

It belongs to the group of nesosilicates, though its composition is primarily based on arsenate rather than silicate. The mineral is typically found in oxidized zones of zinc-arsenic-rich ore deposits.

Geological genesis

Legrandite forms in oxidized zones of zinc-arsenic-rich ore deposits, typically as a secondary mineral resulting from the alteration of primary sulfide minerals under surface weathering conditions. It is commonly associated with other secondary minerals in such environments.
