Cretaceous paleogeography of the West Siberian sedimentary basin

For paleogeographic reconstruction of the West Siberian basin during the Cretaceous we used a set of paleogeographic maps, which were compiled for the main epochs of the Cretaceous period. The paleogeographic maps presented in this study suggest progradational filling of the deep basin with avalanche-type sedimentation during Volgian–Barremian regression. The paleorelief and provenance of terrigenous sediments were reconstructed.
