Abstract
Chelmiec is a hy dro ther mal vein-type car bon ate-sul phide de posit in the Kaczawa Moun tains, where polymetallic Cu-Ni±Co±Ag±Bi min er al iza tion oc curs. Sam ples, col lected from an old dump of the Hintermühlergang vein, were stud ied by re flected light mi cros copy and elec tron microprobe. Two min eral parageneses, Ni-Co±Bi and Cu-Zn-Pb±Sb±Ag, as so ci ated with two stages of precip i ta tion, were dis cov ered in sam ples from the Che³miec de posit. The first stage is as so ci ated with quartz, and is rep re sented by pyrite, ar seno pyrite, gersdorffite, cobaltite, bis muth min er als (na tive Bi, bis muthi nite, and matildite), pyrrhotite, marcasite and chal co pyrite. The sec ond stage as so ci ated with sid er ite and quartz is rep re sented by sulphides (sphalerite, chal co pyrite, ga lena, py rite), tetrahedrite group min er als [tetrahedrite-(Fe), tetrahedrite-(Zn), ten nan-tite-(Zn), and argentotetrahedrite-(Fe)], gersdorffite and bour no nite. Two gen er a tions of sulpharsenides were dis cov ered in the sam ples stud ied. The first is rep re sented by mas sive gersdorffite-cobaltite ag gre gates, the sec ond gen er a tion oc curs as tiny zoned gersdorffite crys tals. Sulpharsenides are char ac ter ized lo cally by pres ence of high amounts of As (up to 1.55 apfu). Sil ver in the Che³miec ores is hosted mainly in tetrahedrite group min er als [from 0.07 to 2.07 apfu in tetrahedrite – (Zn) and-(Fe), and from 4.37 to 4.90 apfu in argentotetrahedrite-(Fe)], less in matildite. In the Sudetes, the pres ence of mas sive sulpharsenides is rare, whereas freibergite is much more com mon. © 2023, Polish Geological Institute. All rights reserved.
