Abstract
A detailed bathymetric map is used to construct a morphotectonic map of the Ulleung Basin. The definition of "morphotectonics" and the procedure of the morphotectonic mapping are described in detail. The morphotectonic structural elements of various orders and ranks are also determined using echo-sounding and other geophysical data. Preliminary analysis shows that the newly determined morpho-structural elements coincide with the locations of deeper tectonic features established by the geophysical evidences of the inner sedimentary and/or crustal sections. Therefore, the tectonic zone of the Ulleung Basin has imprinted the patterns of the inherited evolution since Neogene.e Neogene.
