The crystal structure of a synthetic sulfosalt, TlsAsS4, has been refined. The crystal is orthorhombic with space group Pnma .. Four formula units are contained in a unit cell of dimensions a = 0.8893(3), b = 1.0868(5) and c = 0.9088(3) nm. The final R-value is 0.04 for 759 observed reflections. The Tl(l) has seven nearest S atoms with a mean Tl-S bond length of 0.329 nm. Tl(2) has five nearest...

The Chah-Shaljami polymetal ore deposit contains heavy metal anomalies in various mineralization zones. Geochemical distribution and correlation of elements in surficial soilsindicate that sulfide, sulfate, sulfosalt and silicate mineral occurrences (e.g. Pyrite, chalcopyrite, galena, sphalerite, molybdenite, enargite, hornblend and biotite) in mineralization and stockwork zones resulted in the...

Abstract Kobellite is a Pb-Bi-Sb sulfosalt with minor amounts of (Cu, Fe) and the crystal structure composed two types rods, one which has unusual lateral extensions (‘lobes’), depart from usual lozenge-shaped rod cross-section in sulfosalts. Several Pb-Sb-rich sulfosalts form small group built on similar principles. Some them are related by homology (e.g., izoklakeite), differ perpendicular di...
