Description
Summary:Morphostructural analysis of the stream network in the southern part of the Far East has been carried out. It has been established that the latest vertical movements in the region were manifested against the background of an older, partially eroded relief. Three stages of relief development are identified, reflecting neotectonic activity in the region: (a) pre–Oligocene, characterized by a more intense uplift of the Bureya Ridge, and less intense, the Sikhote-Alin Ridge; (b) Oligocene–Pliocene, characterized by the most intense vertical movements in the region during the period from the Late Eocene to the Holocene; and (c) the Pleistocene and the Holocene, during which a modern erosion-denudation relief was formed and no vertical movements of significant amplitude occurred. A map of the total amplitude of vertical neotectonic movements is constructed.
