한국 남동해역에서 취득된 고해상 탄성파탐사자료의 해석에 의하면 연구해역에 분포하는 후 제4기 해침 퇴적층은 6개의 퇴적단위로 구성된다. 서로 다른 특징을 갖는 퇴적단위는 침식면에 의해 분리되는 2개의 퇴적단위(paralic and marine units)로 구분된다. 침식면위에 놓이는 paralic unit의 경우는 연안침식 작용으로부터 보존된 퇴적단위로 침식수로 충진퇴적단위, 고 해빈-연안 퇴적단위, 하구역퇴적단위 등을 포함한다. paralic unit의 상부는 침식면의 특징을 가지며 그 위에marine unit이 놓인다. Marine unit은 해침에 따른 연안침식에 의해 생석된 퇴적물로 구성되며 중간대륙붕 및 내대륙붕 사질퇴적층, 중간대륙붕 사퇴퇴적층 등이 포함된다. 연구해역에 분포하는 6개의 퇴적단위로 구성되는 해침퇴적층의 형성은 해침기간 동안 상대적 해수면 상승, 퇴적물 공급 및 해양 퇴적기작의 영향에 의해 조절되었다.

Abstract ▼ AI-Helper

Analysis of high-resolution seismic profiles acquired from the southeastern continental shelf of Korea reveals that the late Quaternary transgressive deposits consist of six seismic units created in response to sea-level rise. These units with different seismic facies and geometry can be grouped into two distinct depositional wedges (paralic and marine) bounded by a ravinement surface. The paralic component underlying the ravinement surface consists of the sediment preserved from shoreface erosion and contains incised-channel fill, ancient beach-shoreface deposit and estuarine deposit. The top of paralic unit is truncated by a ravinement surface and overlain by marine component. The marine component consists of the sediment produced through shoreface erosion during landward transgression and contains mid-shelf sand sheet, mid-shelf sand ridge and inner shelf sand sheet. Such transgressive stratigraphic architecture of six sedimentary units is controlled by a function of lateral changes in the balance among rates of relative sea-level rise, sediment input and marine processes at any given time.

문제 정의

Such deposits are well recorded on the seafloor and bear witness to complex interplay between depositional and erosional processes, associated with sea-level changes. For reasons of these features, the study area is an important site for better understanding of depositional and erosional processes during the late Quaternary. The present study focuses on the area from the inner shelf to shelf margin, where abundant seismic evidences are linked to the existence of transgressive depositional and erosional processes.

제안 방법

The present study focuses on the area from the inner shelf to shelf margin, where abundant seismic evidences are linked to the existence of transgressive depositional and erosional processes. In this paper, we attempt to describe acoustic characters and geometries of transgressive units based on high-resolution seismic data, to discuss depositional and erosional processes during the postglacial transgression and finally to reconstruct the transgressive stratigraphic architecture.

대상 데이터

The study area located between the Korean Peninsula and Tsushima Island is a seaway connecting the East Sea to the East China Sea (Fig. 1). Many studies, using the combined data of high-resolution seismic profiles and sediment analyses, in this area revealed that relative sea-level changes coupled with sediment input from the Nakdong and Seomjin rivers have played a major important role in the development of the late Quaternary sequence on the shelf (Park and Yoo, 1988, 1992; Suk, 1989; Min, 1994; Yoo et al.

Unit P1 is regarded to have formed during that time and/or the early period of sea-level rise at slower rate. The study area was a narrower seaway, connecting the East China Sea to the East Sea (Park and Choi, 1986). So the longshore current, passing through the seaway, was much stronger than that of today to play an important role in shaping and creating unit P1.
