The time and source of Late Cenozoic drainage network alteration in the seaside part of the West Priokhotye

Abstract

During Late Cenozoic numerous alterations of the drainage network in the seaside part of the West Priokhotye took place. Different types of alterations are revealed on the basis of loose sediment analysis and relief formation history. In the Miocene and Early Pliocene alterations happened due to orogenic movements of land and Okhotsk Sea basin deepening. In the Late Pliocene-Pleistocene epoch three stages of alteration took place: Late Pleiocene- Early Plestocene, the beginning of Middle Pleistocene and Middle Late Pleistocene. The Aldan glaciation (Q24) and sea level changes strongly affected this process. The alterations were situated by the most part in the Lantaro-Nemuyskaya basin, where differential block movements prevailed.
