Badania mineralogiczno-petrograficzne kruszców Pb-Zn w triasie dolnym w północnej części regionu śląsko-krakowskiego

The study of new occurrences of Pb-Zn mineralization in the Lower Triassic rocks in the NE part of the Silesian-Cracow region was performer. Pb-Zn ore minerals occur in sandstones, gravels and oolitic dolomites and are represented by galena, sphalerite, pyrite, marcasite and an admixture ofchalcopyrite. Vein minerals: barite with celestite, calcite and partly anglesite were also found.

A new association of ore minerals has been found in the Lower and Middle Triassic rocks in the vicinity of the village of Woźniki in the NW part of the Upper Silesian district. In addition to the typical Zn-Pb-Fe association in dolomites, copper sulphides have been detected in the sandstones and conglomerates of the Lower Bunter. Copper mineralization occurs in the sandstone matrix and is represented by bornite, chalcopyrite, chalcocite, tetrahedrite and covellite. High admixtures of zinc in Cu sulphides and admixtures of copper in Zn-Pb sulphides suggest a common source for the metal-transporting fluids and a single period of sulphide crystallization.
