Seismostratigraphic Analysis in Paleogeographic Reconstructions of Isolated Basins: The Case of the Early Oligocene Solenovian Crisis in the Eastern Paratethys

The methodological approaches of seismostratigraphic analysis are tested in paleogeographic reconstructions of the Eastern Paratethys separate basins, which were isolated from the World Ocean in various periods. The scales and consequences of the Early Oligocene Solenovian regression are assessed for the territory of the Eastern Paratethys. Based on the paleogeographic reconstructions and data on the changes in the geodynamic setting of the Black Sea–Caspian region, we reconstructed the depths of the Early Oligocene (Solenovian) basin of the Paratethys for its initial (transgressive), transitional, and final (regressive) stages. Our model takes into account the oscillations of the relative sea level, as well as the influence of later tectonic deformations on the structure of the Oligocene basin.
