Bismuth minerals from the Karkonosze massif

Abstract

The paper presents the results of ore microscopy, chemical, and X-ray studies of emplectite, nuffieldite, bismuthinite and native bismuth from a tungsten-tin-suIfide mineralization in aplite-granites exposed at Szlarska Poręba Huta, NW part of the Karkonosze massif, Sudetes. Implications of importance of these minerals for geothermometry are also evaluated.
