Preliminary Data on Bismuth Telluride from Izerskie Garby Zone, Karkonosze-Izera Block, South-Western Poland

[摘要] This paper describes the first occurrence of bismuth telluride in the Izerskie Garby contact zone. In nature, there are 4 known bismuth tellurides: hedleyite (Bi7Te3), pilsenite (Bi4Te3), tsumoite (BiTe) and tellurobismuthite (Bi2Te3). They are typical accessory minerals of the polymetallic skarns. The Ca-skarns of the "Stanisław" quarry in the Izerskie Garby, bismuth telluride occurs in association with pyrrhotite, chalcopyrite, sphalerite, and wollastonite and tend to form irregular clusters up to 40μm long and 15μm width . Research methods used so far (SEM) does not allow for unequivocal identification of studied mineral. Therefore, it is necessary to conduct further tests using the electron microprobe.
