Abstract

During the Oligocene-Holocene Tethyan collisional tectonics, compressional deformations of two recognizable types developed inside the Northern Peri-Tethyan areas up to 1500 km to the North of the collision front: long-wave (400-600 km) deformations of topography (vertical amplitude 200-500 m), and inversional thrusting/folding. The Black Sea and Southern Caspian basins experienced rapid subsidence at the same time. The compressional structures and the long wavelength intraplate deformations of topography would result from gentle whole-lithospheric folds. The dynamics of the intraplate compression is complex: stress related to collision, ridge push, plate-driving forces, and Oligocene-Neogene global plate kinematic reorganizations.
