Preliminary Seismic Interpretation in the South Sea of Korea (North Eastern Part of the East China Sea)

Abstract

As a part result of \\\\'National Exploration of Marine Resources in the Korea Exclusive Economic Zone (EEZ)\\\\' Project, we prepared 54-channel seismic and shallow Chirp seismic profiles, and magnetic and gravity anomaly chart of 1,980 line-km geophysical data. The study area is located in the northeastern margin of the East China Sea Basin. The sedimentary basin are formed by the graben and/or half-graben basin as rifted activities. The sedimentary basin are composed of pre-rift and syn-rift sediments and post-rift sediment bounded by regional unconformity. The pre-rift and syn-rift sediments consist of Eocene, Oligocene, early Miocene, and middle Miocene sequence, and the post-rift sediments consist of late Miocene and Plio-Pleistocene sequences.
