Abstract:

This paper is manily to treat the change regularity of the contens,distributions, enrich coefficients and correlative coefficients of some trace and constant elements in the sediments of Late Quaternary rock core from Yanwo Lake in the Great Wall Station area, King George Island and to discuss the sedimentary sources in Yanwo Lake and the periodical changes of Late Quaternary climate and the environment in the area. It is concluded that the elastic sedimentary rocks, including volcanic sedimentary rocks, around Yanwo Lake are the major sources of Yanwo Lake sedimentsi the mantle material is also one of its sources and what is more, the continent-sourced materials are transported by the Antarctic glacier.

Key words: elemental geochemistry, lacustrine deposits of Late Quaternary, Yanwo Lake, King George Island
