| Abstract | Organic matter occurrence: Black and dark brownish layers as well as dark coatings around anhydrite nodules are enriched in organic matter. The fine grained mineral paragenesis within these zones consists of potassium feldspar, dolomite, pyrite, marcasite and apatite. These minerals are embedded in a dense organic-rich groundmass (Fig. 1b). The thicker layers with a high amount of organic matter display ductile flow features indicated by foliation, aligned and stretched minerals and rounded porphyroclasts (Fig. 1a). To develop such ductile shear zones a low viscosity and relatively low strain rates are required. These zones indicate a viscous mobilization of the organic matter. |
