Neotectonics of the Manych Trough

摘要

The general (regional) and local neotectonic features of the Manych Trough have been discussed. It has been shown that the trough's bottom was generally immersed at a slow but stable rate of 0.1 mm/year with an amplitude of 40-50 m. Additionally, migration of portions of the maximal and minimal immersion has been identified. All the local tectonic rises in the Manych Trough were thresholds during the existence of the strait in the past and various evidence for their neotectonic activity, with the maximums in Early and Late Khazarian epochs, has been found.
