Vanadate Minerals
Arsenate minerals usually refer to the naturally occurring orthoarsenates, possessing the (AsO4)3− anion group and, more rarely, other arsenates with anions like AsO3(OH)2− (also written HAsO42−) (example: pharmacolite Ca(AsO3OH).2H2O) or (very rarely) sO2(OH)2sup>− (example: andyrobertsite). Arsenite minerals are much less common. Both the Dana and the Strunz mineral classifications place the arsenates in with the phosphate minerals. Example arsenate minerals include: *Annabergite Ni3(AsO4)2·8H2O * Austinite CaZn(AsO4)(OH) * Clinoclase Cu3(AsO4)(OH)3 *Conichalcite CaCu(AsO4)(OH) * Cornubite Cu5(AsO4)2(OH)4 * Cornwallite Cu2+5(AsO4)2(OH)2 * Erythrite Co3(AsO4)2·8H2O *Mimetite Pb5(AsO4)3Cl * Olivenite Cu2(AsO4)OH Nickel–Strunz Classification -08- Phosphates IMA-CNMNC proposes a new hierarchical scheme (Mills et al., 2009).

Lyonsite
Lyonsite ( Cu3 Fe+34( V O4)6) is a rare black vanadate mineral that is opaque with a metallic lustre. It crystallizes in the orthorhombic crystal system. Lyonsite often occurs as small tabular typically well formed crystals. Lyonsite has a good cleavage and a dark gray streak. Lyonsite occurs as a sublimate in volcanic fumaroles. It is often associated with howardevansite and thenardite. It was first described in 1987 for an occurrence on the Izalco volcano, El Salvador. It was named for mineralogist John Bartholomew Lyons (1916–1998) of Dartmouth College. It has also been reported from a mine dump in the Lichtenberg Absetzer Mine of Thuringia Thuringia (; officially the Free State of Thuringia, ) is one of Germany, Germany's 16 States of Germany, states. With 2.1 million people, it is 12th-largest by population, and with 16,171 square kilometers, it is 11th-largest in area. Er ..., Germany.

Lammerite
Copper arsenate (Cu3(AsO4)2·4H2O, or Cu5H2(AsO4)4·2H2O), also called copper orthoarsenate, tricopper arsenate, cupric arsenate, or tricopper orthoarsenate, is a blue or bluish-green powder insoluble in water and alcohol and soluble in aqueous ammonium and dilute acids. Uses Copper arsenate is an insecticide used in agriculture. It is also used as a herbicide, fungicide, and a rodenticide. It is also used as a poison in slug baits. Copper arsenate can also be a misnomer for copper arsenite, especially when meant as a pigment. Natural occurrences Anhydrous copper arsenate, Cu3(AsO4)2, is found in nature as the mineral lammerite. Copper arsenate tetrahydrate, Cu3(AsO4)2·4H2O, occurs naturally as the mineral rollandite. Related compounds Copper arsenate hydroxide or basic copper arsenate (Cu(OH)AsO4) is a basic variant with CAS number 16102-92-4. It is found naturally as the mineral olivenite. It is used as an insecticide, fungicide, and miticide. Its use is banned in Thailand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xanthiosite
Xanthiosite is a nickel arsenate mineral. It was first discovered in Germany in 1858 and named by Gilbert Joseph Adam in 1869.

Alarsite
Alarsite (AlAsO4) is an aluminium arsenate mineral with its name derived from its composition: aluminium and arsenate. It occurs as brittle subhedral grains which exhibit trigonal symmetry. It has a Mohs hardness of 5-5.5 and a specific gravity of 3.32. It is semitransparent, colorless with pale yellow tints and shows a vitreous luster. It is optically uniaxial (+) with refractive indices of nω = 1.596 and nε = 1.608. It was reported from fumaroles in the Tolbachik Tolbachik () is a complex volcano, volcanic complex on the Kamchatka Peninsula in the far east of Russia. It consists of two volcanoes, Plosky (''flat'') Tolbachik (3,085 m) and Ostry (''sharp'') Tolbachik (3,672 m), which as the names suggest a ... volcano, Kamchatka, Far Eastern Region, Russia. It occurs in association with fedotovite, klyuchevskite, lammerite, nabokoite, atlasovite, langbeinite, hematite and tenorite.
