Abstract

Structural refinements of Sn-rich and Sn-poor colusite from the Lorano marble quarry, Italy, revealed that the crystals are isometric and belong to space group P4̄3n. Crystallographic properties are described. Another isometric sulfosalt, arsenosulvanite [Cu3(As,V,Sb,Fe,Ge)S4], with X-ray and optical properties similar to colusite, has been introduced in the mineralogical literature. The results of the present study and a review of the literature on the chemical composition, X-ray crystallography, and crystal chemistry of colusite and arsenosulvanite strongly suggest the same identify for the two species. -from Authors
