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

Abstract

Mineralogical-petrographic study of Pb-Zn ores in Lower Triassic rocks in the northern part of Silesian-Cracow region.A b s t r a c t. The study of new occurrences of Pb-Zn mineralization in the Lower Triassic rocks in the NE part of the Silesian-Cracowregion was performer. Pb-Zn ore minerals occur in sandstones, gravels and oolitic dolomites and are represented by galena, sphalerite,pyrite, marcasite and an admixture of chalcopyrite. Vein minerals: barite with celestite, calcite and partly anglesite were also found.
