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 ...

Hydrologically sensitive carbonates: Tectonic and groundwater controls on synrift sedimentation in the Late Jurassic–Early Cretaceous of the western Cameros Basin, Northern Spain

The Depositional Record
Basin hydrology and subcrop are key controls on carbonate sedimentation in continental basins. Hydrologically sensitive carbonates can record groundwater fluctuations within an aquifer in deep time.

Re-excavation and Interpretation of Key Sections in the Purbeck Group (Tithonian-Berriasian): Teffont Evias, Vale of Wardour, Wiltshire, England

Geoconservation Research
The largely non-marine Tithonian-Berriasian (terminal Jurassic–basal Cretaceous) Purbeck Group of the Vale of Wardour, Wiltshire, western England, was well exposed during the nineteenth century and yielded numerous fossils, notably a rich insect fauna ...

The Berriasian genus Groebericeras in Argentina and the problem of its age

, 1999
Groebericeras bifrons Leanza is described from the Chacao Formation of central Mendoza and the Lo Valdés Formation of central Chile. The species appears limited to the Argentiniceras noduliferum Zone, which is traditionally placed in the lower Berriasian.
