불암산의 지형 경관과 기후지형학적 특색

Abstract

This work is to describe the morphological landscape of the Bulam mountains, and attempts to elucidate the weathering features and properties of the study area on the morphoclimatic viewpoint. The lanscape of the Bulam mountains is characterized by granite domes and rocky cliffs, tors, tafoni, chicot, etc. Laminated structures appear in the weathered mantles and the slope deposits of the eastern and western sides of the study area. These cryogenic structures are directly or indirectly related to the deep freezing from the last glacial age even through today. It seems that the abudant products of coarse sandy grains in the study area are related with the superficial disintegration resulted from strong frost shattering. Nevertheless, in the granitic rocky mountains with low ecopotetial, there is much water supplied from subsurface. Low relief hills appear at the foot of eastern parts of the mountains, and weathering conditions of todays are caused mainly by frost shattering. In spite of these conditions, chemical alterations strongly affect to the regolith under transported slope materials, owing to sustainable humid conditions by subsurface water rather than by climatic milieu.
