For this research, undulating denudation surface around Kangnung and Sokcho are surbeyed. 1) Denudation landfrnm are distributed at the altitude of 20 to 150 meters along eastern slopes of the Taebaek mountains. Bedrocks of denudation surface consist of granite and are deeply-weathered. The thickness of the weathered crust presumed to be 15meters at least. 2) At present, the denudation surfaces are dissected into undulating hills revealing concordant summit level. From this fact, it might be concluded that the undulating hills of concordant summit level should be remnant of former denudation surface. This can be interpreted that more flatted denudation surface had been exist before the unduating denudation surface is developed. It is assumed that the dissection of the denudation surface took place during the pleistocene epoch. 3) There are no deposits on denudation surface. This fact imply that fluvial erosion did not occurred actually. Corestones, usually from about 0.5 to 5m in diameter, are included in weathered crust of denudation surface, and sometimes they are exposed in the earth`s surface. Dome-shaped hills that are similar to inselberg stand in isolation admist undulating denudation surface. Accordingly, it is estimated that denudation surface had been developed as a result of deep weathering of granite and the denudation of weathered products.Read More
