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) [AsO2(OH)2]- (example: andyrobertsite). Arsenite minerals are much less common.[1] Both the Dana[2] and the Strunz[3] mineral classifications place the arsenates in with the phosphate minerals.

Example arsenate minerals include:

Nickel-Strunz Classification -08- Phosphates

IMA-CNMNC proposes a new hierarchical scheme (Mills et al., 2009). This list uses it to modify the Classification of Nickel-Strunz (10 ed, pending publication).

  • Abbreviations:
    • "*" - IMA/CNMNC status: discredited.
    • "?" - IMA/CNMNC status: questionable/doubtful.
    • "REE" - Rare-earth element (Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu)
    • "PGE" - Platinum-group element (Ru, Rh, Pd, Os, Ir, Pt)
    • 03.C Aluminofluorides, 06 Borates, 08 Vanadates (04.H V[5,6] Vanadates), 09 Silicates:
      • Neso: insular (from Greek νησος nēsos, island)
      • Soro: grouping (from Greek σωροῦ sōros, heap, mound (especially of corn))
      • Cyclo: ring
      • Ino: chain (from Greek ις [genitive: ινος inos], fibre)
      • Phyllo: sheet (from Greek φύλλον phyllon, leaf)
      • Tekto: three-dimensional framework
  • Nickel-Strunz code scheme: NN.XY.##x
