Sulfarsenide mineral

Add article description

The sulfarsenide minerals are a subgroup of the sulfide minerals which include arsenic replacing sulfur as an anion in the formula.[1] Antimony and bismuth may occur with or in place of the arsenic as in ullmannite. The chemical formula of a sulfarsenide looks like a sulfosalt, however the structures are distinctly different. In sulfosalts the arsenic replaces a metal ion.[1]

The sulfarsenides are grouped with the sulfides in both the Dana and Strunz mineral classification systems.[2][3]

Examples include:[1][4][5]

  • Arsenopyrite group:
    • Arsenopyrite FeAsS
    • Glaucodot (Co,Fe)AsS
    • Gudmundite FeSbS
    • Lautite CuAsS
    • Alloclasite (Co,Fe)AsS
  • Cobaltite group
