초록
Landform development in the Yeonhwa and Waryong mountains reflects the tectonic movements and weathering patterns on the southern coast of the Korean Peninsula. Here, tectonic movements acted in the following directions at different times: ① northeast-southwest, ② south-north, and ③ east-west. The movements have arranged the landform of the mountains along these directions. Specific landforms varied depending on the patterns of rock weathering. Granodiorite developed a high density of horizontal joints due to their internal gneissosity. This led to the formation of plate-like rock debris and the development of large-scale block stream and talus. The Haman Formation was fractured along the bedding and formed small rock debris like normal sedimentary rocks, but the Jindong Formation affected by contact metamorphism developed relatively widely spaced horizontal joints due to compression and melting of the strata. Because of this feature, tors and cliffs developed well in areas where the Jindong Formation occurred. The andesite was very resistant to weathering due to the filling of weathering products into microfractures, so it tended to form monolithic rocks without small valleys.
Abstract
Landform development in the Yeonhwa and Waryong mountains reflects the tectonic movements and weathering patterns on the southern coast of the Korean Peninsula. Here, tectonic movements acted in the following directions at different times: ① northeast-southwest, ② south-north, and ③ east-west. The movements have arranged the landform of the mountains along these directions. Specific landforms varied depending on the patterns of rock weathering. Granodiorite developed a high density of horizontal joints due to their internal gneissosity. This led to the formation of plate-like rock debris and the development of large-scale block stream and talus. The Haman Formation was fractured along the bedding and formed small rock debris like normal sedimentary rocks, but the Jindong Formation affected by contact metamorphism developed relatively widely spaced horizontal joints due to compression and melting of the strata. Because of this feature, tors and cliffs developed well in areas where the Jindong Formation occurred.
