Arsenates occur naturally in a variety of [[mineral]]s. Those minerals may contain [[hydrated]] or [[anhydrous]] arsenates. Unlike phosphates, arsenates are not lost from a mineral during [[weathering]]. Examples of arsenate-containing minerals include [[adamite]], [[alarsite]], [[annabergite]], [[erythrite]] and [[legrandite]].<ref>[[Mineralienatlas:MineralSystematik#x37.|Mineralienatlas - Mineralklasse Phosphate, Arsenate, Vanadate]]. {{de icon}}</ref> Where two arsenate ions are required to balance the charge in a formula, it is called '''diarsenate''' for example trizinc diarsenate, Zn<sub>3</sub>(AsO<sub>4</sub>)<sub>2</sub>.
