BITUMINOLOGICAL INDICATORS PROSPECTS OF OIL AND GAS POTENTIAL IN THE WESTERN OF THE SIBERIAN PLATFORM

Comprehensive geochemical studies were carried out in the west of the Si-berian platform in the basin of the river. Podkamennaya Tunguska. According to the bituminological indicators in the terrigenous-carbonate rocks of the Middle-Upper Cambrian and Ordovician age of the hypergenesis zone, 62 anomalies were estab-lished. In structural and tectonic terms, 38 bituminological anomalies are confined to local positive structures, which can be considered promising for oil and gas explora-tion
