Geomorphlogy of northen flange of the Kuril deep-sea basin

Abstract

Some new data are discussed on the northern flange of the Kuril deep-sea basin in the Sea of Okhotsk. The continental slope is proved to have block-stepped structure, linear depressions between the blocks being traps for sediments. A continental rise is identified as an individual morphological zone differing in stages of evolution. A conclusion on recent downwarping of the basin floor is based on geomorphic features.
