Arsenite minerals

From Wikipedia, the free encyclopedia

Arsenite minerals are very rare oxygen-bearing arsenic minerals. Classical world localities where such minerals occur include the complex skarn manganese deposit at Långban (Sweden) and the polymetallic Tsumeb deposit (Namibia). The most often reported arsenite anion in minerals is the AsO33- anion, present for example in reinerite Zn3(AsO3)2. Unique diarsenite anions occur i. e. in leiteite Zn[As2O4] and paulmooreite Pb[As2O5]. More complex arsenites include schneiderhöhnite Fe2+Fe3+3[As5O13] and ludlockite PbFe3+4As10O22.[1][2][3]

Nickel–Strunz Classification -04- Oxides[edit]

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:
    • "*" - 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
    • 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
