The purpose of this study is to elucidate the characteristics and origins of largy angular blocks mantle on the slope of Mt. Moo Deung. For this purpose, the shape, size, sedimentary facies of blocks, the fabric of the surface blocks are analyzed and examined The results are as follows: 1. Blocks mantle consists of angular boulders in average 0.5-1m. The blocks are hard rock, but the surface area of blocks is slightly weathered, for example, micro weathered features, tafoni. 2. The $quot;a$quot;orientation of the surface blocks tends to be parallel to the local slope and the $quot;a$quot;dip is less steeply inclined by 10 degree than local slope gradient. 3. The sedimentary facies of blocks consist of four layered structure showing from top to bottom (1)angular boulders interlocked with no fine material matrix (2)angular blocks m cobble size with no matrix, since the surface area of this blocks is very thinly coated with reddish yellow silt and clay. the surface of blocks is changed in color. (3)interstitial humic mud between the angular blocks in pebble size (3)angular pebbles with reddish yellow silty sand and clay matrix. This layer rests on deep weathered basal rock. 4. The blocks mantle of Mt. Moo Deung is a kind of block slopes formed under periglacial conditions during late Pleistocene. 5. The present writer suggests that block slopes of Mt. Moo Deung have a developmental history comprising (1)the forming of micro weathered features and deep weathered mentle of basal rock by chemical weathering in the pre-Pleistocene (2)production of blocky material and development of frost sorting by frost action (3)movement by mass-wasting relevant to solifluction (4)subsequent removal of interstitial matrix and deposition of black humic mud.

무등산 지역의 지형특성에 관한 연구

박승필 한국지형학회 1996 한국지형학회지 Vol.3 No.2

본 연구에서는 무등산 지역에서 발견되는 독특한 지형의 특성을 구명하기 위하여 각종 특징있는 지형을 분류하고 그 생성 ·발달과정을 종합고찰하여 다음과 같은 결론을 얻었다. 1. 무등산은 전체적으로 보아 돔모양의 산지를 이루며 정상부위는 노출암체로 드러난 순상인젤베르그의 모습을 띤다. 2. 풍화혈은 의상봉 일대를 중심으로 나마(gnamma)가 집중분포하며 석영안산암에는 풍화혈의 생성이 상대적으로 미약하다. 심층풍화층은 500∼600m 고도 이하에서 많이 관찰되며 그 상부에 거력이나 각력층을 얹고 있는 경우가 많다. 3. 거력층을 다음과 같이 네가지 타입으로 구분하였다: 거력군으로 드러난 타입, 거력의 일부분이 토양층 위로 드러난 타입, 거력이 토양층 속에 잠입하여 있는 타입, 거력층이 골짜기를 메우고 있는 타입이다. 이들 거력층은 주빙하기후환경에서 solifluction(또는 gelifluction)에 의하여 운반 퇴적된 후 부분적으로 세립질이 세탈되었다. 4. 고도 800∼900m와 500∼600m에서 평탄면으로 인정되는 지형면을 에취플레인이 변형된 화석 에취플레인으로 사료된다. 5. 무등산의 고도 800∼900m의 평탄면과 고도 500∼600m의 평탄면은 그 사이에 급경사의 산사면(경사각이 25∼35°)을 사이에 두고 있다. 이러한 계단상의 지형은 지반이 융기할때에 형성되는 것으로 무등산은 제 3기 이래 완만한 융기운동을 한 것으로 사료된다. 6. 무등산은 제3기의 인젤베르그의 생성 · 발달과정을 거쳐 제4기의 기후환경변화에 따라 온대하천에 의한 선상침식과정과 빙기의 주빙하환경의 영향으로 현재와 같은 변형된 화석 에취플레인/인젤베르그의 지형을 형성한 것으로 사료된다. 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.

영산강 하류 유역에 분초하는 유기물층에 관한 연구 : 양장리 일대를 중심으로 example of Yangjangri

박승필,위현정 한국지형학회 1996 한국지형학회지 Vol.3 No.2

본 연구에서는 영산강 하류 유역의 양장리 일대에 분포하는 충적지에서 관찰된 다량의 유기물을 포함하고 있는 충적층을 대상으로, 퇴적층 구조와 퇴적상을 밝히고 粒度分析 및 花粉分析을 실시하였다. 이를 통하여 양장리 일대 층적층의 특성과 퇴적환경을 究明하였으며, 흑색 유기물층이 소택지 환경에서 생성되었음을 밝혔다. 양장리 일대는 지난 빙기 동안 한냉한 환경 하에서 건특상태의 산골짜기에 sollfluction 퇴적물이 덮이고, 후빙기 이래 기온상승에 따라 해수면이 상승하면서 침수된 후, 소택지가 형성되면서 청회색 또는 암회색의 glei층이 생성되었다. 해수면의 미변동을 겪으면서 본 연구지역은 B.P. 1,645±75년 경에는 육지화한 상태였으며 해수가 침입되지 않는 위치였으나 다시 해수면의 상승으로 저습지성의 소택지화한 후 흑색유기물층이 형성되었다. The study area Is a 「Yangjangri」, which is located near of estuary in Yeongsan River. The purpose of this study is to find the depositional environment of organic matter layers in alluvial deposits at Yangjangrl area and to clarify the geomorphic development of these deposits in relation to post-glacial sea level changes. The analytic methods, such as the classification of micro topography and the analysis of depositional facies of boring data, grain size and pollen are employed for this study. The main findings are as follows; The organic matter layers(7.5Y 2/1) found in a Yangjangri were caused by bog sediments which were formed In the process that river valleys were downed under the periglacial climatic environment of the last glacial age and then buried by the transgression of post glacial age. Namely, the study area was influenced by the sea-level fall during 1645±75y. BP. and then covered with the bog sediments formed through the sea-level rise.

월출산의 지형과 수문 환경

Mt. Wolchul has changed shape a lot in view of prototypical etchplain/inselberg. However it seems to stem form inselberg in that its overall figure keeps dome-shaped. The flat at a height of about 200-300m seems to be fossil-like etchplain, whose flat have been somewhat changed. The ancient landform and V-tape valley, found at a height of about 400-600m, 200-300m and 50m, seems a topographic evidence stemming from long-range ground movement. In general, the tafoni of exposed rock-desks is 10-40㎝ in diameter expect for a few several centimeter ones. Tor found in Mt. Wolchul can be classified into three type, citadel-copy, ground for and independent tor. Expect for talus of block fields in Mt. Wolchul takes its present location by way of sliding motion such as solifluction(or gelifluction). Mt. Wolchul takes transformed fossil-like etchplain/inselberg landform through inselberg generation and development process during Tertiary and Quarternary; erosion by tropics river under the climatic changes and periglacier environment of the glacial Age. Water circulation structure of Mt. Wolchul with premature soil shows an urban type effluence(where flow increases rapidly in a short time in case of rain); for it loses a lot in the first stage by the fraction with exposed side of bed rocks; has considerable amount of direct flow. EC density differs to the exposure degree of bed rocks.
