Arsenite mineral (original) (raw)

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 Zn[As2O4] and Pb[As2O5]. More complex arsenites include Fe2+Fe3+3[As5O13] and PbFe3+4As10O22.
