The Cenozoic stress/deformation fields of the Donets coal basin and their probable sources

The periodicity, dynamics and kinematics of unadequately studied Cenozoic activities in the Donets intraplate foldbelt (“the Donbass”) and in its neighbourhood were considered. It have been demonstrated that two independent orogenies divided by a tectonic pause in the Eocene-Oligocene took places there, the Laramic one (the terminal Maestrichtian – Paleocene) of an early Alpine tectonic epochs and conventiolly neotectonic one (Early Miocene – Quaternary) of a late Alpine epoch.
