Abstract

THE SEPTARIAN MINERALIZATION IN CARBONATE CONCRETIONS FROM THE LUBLIN COAL BASINAbstract. The article presents the mineralogical and petrographic characterization of septarian mineralization in the Lublin Coal Basin. Cracks and caverns in Carboniferous siderite concretions are filled with crystalline carbonates: siderite–magnesite solid solution series, calcite and dolomite as well as clay minerals, sulphates, apatite and quartz. The accompanying ore minerals such as pyrite, bravoite, millerite, chalcopyrite, sphalerite and galena are also present
