Abstract
Oil and bitumen shows with previously unknown hydrocarbon biomarkers – 9-methyl, 8-14-secohopanes – were encountered in the sections of hydrogeological wells on the northeastern slope of the Aldan anteclise. Shows of biodegraded asphaltites are confined to the cavernous horizon in the middle Cambrian limestones of the Tankhai Formation. The relatively high residual concentrations of the “new” biomarkers are due to their very high resistance to biologic oxidation processes. Geologic materials and geochemical data on the studied naphthides suggest that in the region under consideration there is a typical oil deposit sealed in the “head” of the cavernous horizon by highly viscous bitumens.
