Abstract
Sterane hydrocarbons (HCs) of bitumoids of organic matter (OM) from the Lower Cambrian Sinyaya formation of the northern slope of the Aldan anteclise were studied using the chromatography-mass spectrometry technique. Norlanostanes C29 and lanostanes C30 were first discovered in fossilized OM from Cambrian sedimentary basins. This report considers the features of sedimentation, diagenesis, and maturity of lanosteroid-containing organic matter. Lanostane HCs are recommended for usage as biomarkers of oilproducing rocks of the Sinyaya formation to determine the source of naphthides in the eastern part of the Siberian platform.
