arsenate mineral

{{Short description|Naturally occurring orthoarsenates}}

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.[http://webmineral.com/dana/dana.php?class=45 Webmineral] Both the Dana[http://webmineral.com/danaclass.shtml Webmineral Dana system] and the Strunz[http://webmineral.com/strunz.shtml Webmineral Strunz system] 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 (mindat.org, 10 ed, pending publication).

  • Abbreviations:
  • "*" - discredited (IMA/CNMNC status).
  • "?" - questionable/doubtful (IMA/CNMNC status).
  • "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
  • NN: Nickel–Strunz mineral class number
  • X: Nickel–Strunz mineral division letter
  • Y: Nickel–Strunz mineral family letter
  • ##x: Nickel–Strunz mineral/group number, x add-on letter
