Dojrzałość materii organicznej w odmianach litologicznych łupku miedzionośnego NE części złoża Rudna – związek z mineralizacją kruszcową oraz przejawami obecności ciekłych węglowodorów

Rock samples collected from Kupferschiefer deposits showstrong lithological diversity in the vertical section. The content of organicmatter (OM) gradually decreases towards the top of the shale section. Thepore spaces of the Kupferschiefer contain solid bitumens. We also foundfluid inclusions with liquid hydrocarbons in calcite and dolomite that formparagenetic associations with Cu-Ag minerals. The degree of maturity ofOM in the shale samples is insufficient to generate liquid and gaseoushydrocarbons; therefore, the genesis of local accumulations of these hydrocarbons is probably related to the migration of hydrother-mal solutions responsible for the origin of the Cu-Ag ores. As a potential source of liquid and gaseous hydrocarbons can be indicatedstrongly thermally altered Lower Carboniferous deposits and/or locally thermally altered Lower Zechstein formations rich in OM,strongly affected by oxidizing hydrothermal solutions genetically related to the development of the Rote Fäule facies
