A Study on Geology and Geomorphic Development of Mt. Juheul

This study is conducted as a part of the Collective Academic Research of Mt. Ju-heul in Munkyeong, Gyeongsangbuk-do 2011 and covers Pyeongcheon-ri, Yeongsan-ri, Jigog-ri, the eastern area of main ridge of the mountain. The study is mainly constituted with twice field works, laboratory survey and analysis of topographical/geological maps. As a result, the whole view of Mt. Ju-heul is deeply related with the geological structure and distribution of the rocks. Especially, Paekhwasan and Chobong Formation of Ogchon System around the upper slope areas make the hardness disparity with Granites of Gyeongsang System on the right side of them and this mechanism accelerates the unique process of slope development the eastern area of Mt. Ju-heul. This process of slope development can be classified into following three categories; First, process of slope development around the upper slope areas where Ogchon System rocks and Gyeongsang System rocks alternately combines. Second, process of slope development around transition zone which has thick regolith caused by chemical deep weathering. Third, process of slope development on the gentle slope areas in which the transported weathered-materials has been deposited is dominant.
