Morphostructure of lake basins of the Lower Amur region

Abstract

Large lake basins in the Lower Amur drainage basin correspond to remnant elevations of basement and marginal steps within intermontane depressions. The lake basins and drainage pattern as well as recent tectonic movements indicate periodical accelerated sinking of the basement remnant elevations and the marginal steps due to densities heterogeneity within the intermotane basins structures.
