江陵段狀地의 考察

Abstract

This paper aims to classify the Kangnung platform area and to make clear its relief forming processes as well as its relief forming stages. The research areas were divided into 3 sections which are the half orange hills situated in the Kwandong college, the Bulhwasan hills and the Kumgwang-pyong.

The half-orange hills with weathered-pebbles scattered on the 40m high summits were formed among the deeply wethered granites. The socalled weathered-pebbles landform on the granite have developed on the depressions which were formed by the leaching provesses in the Mindel/Riss interglacial perion. This landforms is thought to have developed by the disturbance of the depositional beds, which was induced by the chemical weathering during Riss/Würm interglacial period. The fact that the morphodynamic processes progressed throughout the above mentioned interglacial period can be proved by the typically observed outcrops which reveals the clay, silt and sand beds, which are colored by the calcium white beds and iron red beds and which contain pebbles of the Bulhwasan hill slope and the relating hill slopes of the Hyangyo hills.
