Summary:
The Ukrainian Dniepr-Donets Basin (DDB) is a Late Palaeozoic intracratonic rift basin, with
sedimentary thicknesses up to 19 km, displaying the effects of salt tectonics during its entire history of
formation, from Late Devonian rifting to the Tertiary. Hundreds of concordant and discordant salt structures
formed during this time. It is demonstrated that the variety of styles of salt structure formation in the DDB
provide important constraints on understanding the triggering and driving mechanisms of salt kinematics in
sedimentary basins in general. Specifically, syn- and post-rift regional extensional and compressional
tectonic events were very important mechanisms involved in the initiation of salt movements in the DDB.
Other geological processes were significant factors in the development of a variety of salt geometries once
salt flow had been triggered by tectonic disturbance of the unstable equilibrium between salt layers and their
overburden.
