Ayano­-Shevlinsky pericratonic basin of the Siberian Platform, Far East of Russia

The Ayano-­Shevlinsky pericratonic basin along the southeastern margin of the Aldan-­Stanovy shield, the Siberian Platform, contains isolated outcrops of variegated Upper Riphean, Vendian, Cambrian, Ordovician, Silurian, Devonian and Carboniferous clastic­-carbonate deposits, basalts, granitoids and gabbroids of similar formational type as the de-posits of the Yudoma­Maya pericratonic basin located to the north. Stratigraphic hiatuses of varying durations are common throughout the section. Deposits are arranged in folds of different morphologies, from brachiform to isoclinal.
