Abstract
We studied the organochemical distribution of saturated hydrocarbons in organic matter of mudstones of the Vendian Marna Formation in the Sayan-adjacent Biryusa area. The formation is composed of glacial, glacio-alluvial, and lacustrine deposits. In the fraction of saturated hydrocarbons in chloroform extracts (bitumoids), a homologous series of earlier unknown 2,7-dimethyl alkanes has been identified, with molecules having the even number of carbon atoms prevailing. The possible sources of such abundant biomarkers are considered.Keywords
