무등산 지역의 지형특성에 관한 연구 = A Study on the Characteristic Landforms of Mt. Moodeung

다국어 초록 (Multilingual Abstract)

The purpose of this study is to elucidate the characteristic landforms of Mt. Moodeung. For this purpose, characteristic landforms are classified, and creation and development of those are investigated. The results are as follow. 1. Overall landscape of Mt. Moodeung is a dome-shaped mountain and around summit Is a bare shield inselberg. 2. Weathering pits(gnamma) are distrilbuted intensively around the summit of Euisang-bong. the weathering pits do not develop well on the surface of Mudeungsan dacite relatively. Deep weathered layers are observed well under the altitude of 500-600m and the weathered layers are covered with angular boulders or cobbles. 3. Angular boulders deposits are classified Into four types such as: 1) the type of block slope or block stream, 2) the type that the partial portion of block Is exposed to the air. 3) the type that blocks are filled in vally. 4) the type that angular boulers are transported and deposited by solifluction(gelifluction) under periglacial conditions during late Pleistocene. 4. Two planation surfaces are identified at 800∼900m and 500∼600m in altitude by the neighboring mountain ridges and peaks which have approximately the same hight. these ridges and peaks infered to be the transformed relict etchplain. 5. The slopes of Mt. Moodeung compose of three portions: two former planation surfaces of 800∼900m and 500∼600m in altitude, and escarpment which is developed between the former two planation surfaces. these stepped landsurfaces indicate that Mt. Moodeung had experienced gentle uplift movement from Tertiary. 6. The etchplain/inselberg of Mt. Moodeung had been created and developed during Tertiary and Quarternary climatic change forced the temperate river processes to dissect those surfaces and periglacial processes transformed those and now the landform of Mt. Moodeung becomes the fossil etchplain/inselberg.
