Short summary

Erzwiesite, ideally Ag₈Pb₁₂Bi₁₆S₄₀, Z = 1, is a new sulfosalt mineral discovered in the Erzwies mining area, Gastein Valley, Salzburg Province, Austria. The empirical formula is (Ag,Cu)_8.23(Pb,Cd)_11.33(Bi,Sb)_16.31(S,Te,Se)_40.03 (based on 76 apfu). Erzwiesite crystallises in space group Cmcm (a = 4.085(5), b = 13.462(15), c = 33.92(4) Å, and V = 1866(4) Å³). Erzwiesite is the first natural (8:8) homologue of the lillianite homologous series and is named after its type locality.
