우리나라 河口沖積層의 層相構造 = A Stratigraphic Study of River Mouth Alluvium in Korea

다국어 초록 (Multilingual Abstract)

The bedding sequence of river mouth alluvium, being mainly concerned with the post-glacial sea-level transgressive pattern, would be main clues in the studing of post-glacial sea-level change and geomorphic development of alluvial plain. Analytic method of boring data on four river mouth alluvial plains and one tidal flat was used for the clarification of this.
Main findings are as follow;
1. Each alluvial plain has buring valleyes and the thickness of deposits on the valleyes is about 30∼70 meters. (See Fig.3,6.13)
2. The bedding modes of the deposit show three different structure: uncomplete one-cycle in the excessive fluvial deposit supply; complete two, uncomplete two or uncomplete three cycles in the moderate; regardless of the depth one-cycle in the insufficient.
3. Generally, one-cycle on shallow deposits under -20 meters depth, two cycles on deposits more than -30 meters, in the moderate fluvial deposit supply. The bedding sequence and the terms of each bed are as in table 1.
4. The Lower silt-Clay Bed is correlated with sea-level transgression at around 10,000 y.B.P., the Middle Silt-Clay Bed at around 8,000 y.B.P., and the Upper Sand Bed at stable period sice 6,000 y.B.P.
