The aim of the research was to identify the mineral phases of these rocks, especially carbonate phases. The rocks from the roof part of the Bundsandstein profile and floor part of the Muschelkalk profile - Gogolin Beds - are typical sediments from the northern part of Chorzów City. These rocks were mined in the XIX century and the beginning of the XX century. The article also presents the results of research on samples of carbonate rocks taken from investigated strata. It provides a Petrographic description, the results of microscopic analysis executed in polarized, transmitted light, X-ray analysis, and microprobe measurements using a scanning microscope. The results of these analyses showed that dolomites dominate in the Bunsandstein strata. Dolomites (The sampled rocks?) are composed mainly of dolomite, but sparry calcite was also identified. Moreover, quartz, clay minerals, muscovite and iron minerals were observed in the Bundsandstein rocks. The Muschelkalk sedimentsare mainly represented by limestone. In some areas, conglomerates were also found. The conglomerates are composed of carbonate rock boulders connected by carbonate cement. Two generations of calcite were observed while investigating the limestone. The first generation calcite is micritic, and the second generation calcite forms sparry crystals different in size and shape. In some areas of the sparry calcite it is possible to observe perfect rhobohedral cleavage. Moreover, dolomite, rhodohrosite, and noncarbonate minerals like quartz, muscovite, and clay minerals were identified. The results of microscopic analysis also showed that the limestone is different in texture. The limestone presents the following textures: biomorphic, detrical, sparry, microsparry and micritic.}, type={Artykuły / Articles}, title={Mineral phases of carbonate Triassic rocks of the Chorzów area}, URL={http://www.journals.pan.pl/Content/85714/PDF/stanienda-nowak-kukielka.pdf}, doi={10.2478/v10269-012-0019-x}, keywords={Chorzów, Bundsandstein, muschelkalk, Gogolin Beds, carbonate rocks, limestone, dolomite}, }
