| Abstract: | Kerogen separated from rocks of the Upper Jurassic sequence of the Sysol'sk shale-bearing region was investigated by the pyrolytic method in the off-line regime. Multiple alkyl derivatives of thiophene, alkyl benzenes, n-alkanes, alkenes, and isoprenoid hydrocarbons, as well as phenols, were identified in products of the pyrolysis by the chromatomass-spectrometry method. Kerogens from rocks richer in Corg yield a larger fraction of thiophene structures in the pyrolysate composition, indicating the influence of early diagenetic sulfurization of lipids and, possibly, carbohydrates on the accumulation of increased organic matter concentrations in shales. |
