QUANTITATIVE FIELD OBSERVATION ON FROST PHYSICAL WEATHERING IN THE GREAT WALL STATION AREA

Field observing sites were set to measure frost weathering of bedrock in the Great Wall Station Area of Antarctica from 1988 to 1990. The results show that: (1), the weathering rate is higher in summer that in winter; (2), the weathering rate is greater at higher place than at lower place; (3), the weathering rate is higher in east and southeast slopes than in other slopes; (4), the weathering rate is greater in higher mean annual air temperature year than in lower year.
