The Timan-Pechora Basin is a sedimentary basin that lies between the Timan Ridge and the Urals foreland basin. The basin extends into the southern part of the Barents sea and includes Kolguyev Island. It is covered by of sediments that were deposited during a series of marine regression and transgression events from the Proterozoic to the Cenozoic. The eastern basin was deformed when the Ural mountains were formed. The Basin is further divided into the Izhma-Pechora basin, Pechora-Kolva basin, Khoreiver basin and the Northern Pre-Urals.
