Abstract
Lake core sampled from Xihu in Fildes Peninsula of King George Island, Antarctica could reveal the environmental change of the district. The lake core (GA7), 9.28 meters long, was sectioned at an interval of 2 cm. Through measuring the organic carbon, magnetic susceptibility, granularity and organic carbon isotope of GA7, by use of (14)C age it was estimated that there were four periods of high temperature in Fildes Peninsula: 4800 - 4400 aB. P., 3600 - 3350 aB. P., 2100- 1800 aB. P. and 900 aB. P. - present. Meanwhile, results showed that there was a strikingly positive correlation between the content of organic carbon and that of organic carbon isotope (δC(13)org) which could be the substitute indicators of environmental temperature.
