Bazhenov horizon of Siberia (Tithonian – Lower Berriasian): tectonic and hydrodynamic conditions of sedimentation

Georesursy, 2019
The new model of the sedimentation of the Bazhenov Formation, on which black shale accumulated on relative elevation – a shallow-marine hilly plateau, agrees well with the results of a general paleogeographic analysis of the Bazhenov horizon of Siberia ...

Сonditions of sedimentation and paleogeographic zoning of the Bazhenov horizon (Tithon-Lower Berrias) in West Siberia

Georesursy, 2017
In the global Upper Jurassic-Neocomian (Oxford-Valanginian) black-shale interval, the Bazhenov Formation occupies only the Tithonian – Lower Berriasian. The main regional reasons for this localization were the tectonic regime, the morphology of the basin’
