Hydrocarbon exploration and reservoir analysis

Lower Cambrian deposits are found throughout the Soviet Union and Mongolia (Fig. 1). They occur over the entire Siberian Platform, much of the East European Platform, and widely in the fold belts bordering the southern Siberian Platform (the Altay-Sayan Fold Belt, Mongolia—Okhotsk Fold Belt), Kazakhstan, Central Asia, and the Urals. In most cases, they are conformably underlain by Vendian rocks. The most important sections containing Early Cambrian fossils are in Siberia, the East European Platform and Kazakhstan in the USSR, and in western Mongolia. The key region for the Cambrian stages adopted in the USSR is the Siberian Platform.
