Chemistry:Arsenite mineral

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.

Nickel–Strunz classification -04- oxides

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).

    • 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
