Sequence stratigraphic model and Evolution of the Channelized depositional systems during Miocene in Ulleung Basin southeastern margin, East Sea

Abstract

-In the channelized bodies in Ulleung Basin southwestern, the geomtry of the lower base and the characters of internal reflectors suggest that the channelized bodies had formed by several incisions and infillings.- The position of internal incision during the formation of the channelized bodies had been relatively fixed within a zone of the channelized bodies.- Several incisions and infillings in the channelized bodies were most likely caused by smaller-scale (4th and 5th order) relatively sea-level (or accommodation) changes within the 3rd order relatively sea-level (or accommodation).al incision during the formation of the channelized bodies had been relatively fixed within a zone of the channelized bodies.- Several incisions and infillings in the channelized bodies were most likely caused by smaller-scale (4th and 5th order) relatively sea-level (or accommodation) changes within the 3rd order relatively sea-level (or accommodation).
