Abstract
Two interesting associations of Bi minerals were found in the vicinity of the town of Medzev in the Slovenské rudohorie Mts. The first one occurs with quartz and arsenopyrite at Kobaltová vein and is represented by native Bi, bismuthinite, ikunolite, ingodite, benjaminite, matildite and gustavite. The second one was found at the Oriešok vein associated with pyrrhotite, arsenopyrite, cobaltite, sphalerite and galena. The sulphosalts identified there are izoklakeite, tintinaite, Bi-rich boulangerite and Bi-rich jamesonite. An extensive Bi3+ ↔ Sb3+ substitution was observed among studied sulphosalts. The Co anomalies, determined previously by geochemical methods, were explained by cobaltite and Co-rich arsenopyrite. Studied sulphosalts belong to the latest stages of the quartz-sulphidic mineralization in the Gemeric Superunit.
Key words: Western Carpathians, izoklakeite, matildite, gustavite, benjaminite, Bi-rich boulangerite and Bi-rich jamesonite
