Summary In this study Posidonomia shale extracts, Posidonomia shale distillates and extracts of fossil wood (gagat) found in these shales were seperated on GC and identified by GC-MS. Samples were obtained from Dotternhausen oil shale formation (FRG) belonging to LIAS epsilon (Toarcien). Main components were n-alkanes ranging from C7 to C27 with a maximum at C17 for shales and two maxima at C17 and C9 respectively for fossil wood. Isoprenoid hydrocarbons present in shales and fossil wood as well were 2,6,10-trimethyltridecane, 2,6,10-trimethylpentadecane, 2,6,10,14-tetramethylpentadecane (pristane) and 2,6,10,14-tetramethylhexadecane (phytane). Numerous low molecular weight cycloalkanes with 6 to 9 carbon atoms were present in fossil wood. Of these, the main constituent could also be found in shales. Also aromatic hydrocarbon compounds were numerous in the low boiling fraction of extracts of fossil wood. The results obtained are discussed with respect to the maturity of the Dotternhausen sediments.
