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 show strong lithological diversity in the vertical section. The content of organic matter (OM) gradually decreases towards the top of the shale section. The pore spaces of the Kupferschiefer contain solid bitumens. We also found fluid inclusions with liquid hydrocarbons in calcite and dolomite that form paragenetic associations with Cu-Ag minerals. The degree of maturity of OM in the shale samples is insufficient to generate liquid and gaseous hydrocarbons; therefore, the genesis of local accumulations of these hydrocarbons is probably related to the migration of hydrothermal solutions responsible for the origin of the Cu-Ag ores. As a potential source of liquid and gaseous hydrocarbons can be indicated strongly 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.
