%X Geochemical characteristics and chemical weathering of periglacial sediments on the edge of Nelson Ice Cape, Antarctica were studied in a profile. The results show that the periglacial sediments have a close genetic relation to basalt volcanic rocks there. It can be deduced from the analyses of major elements of the periglacial sediments that their source rocks should be at a weak weathering stage, i.e ., the stage of de-Ca (decalcification), de-Mg and de-Na. The chemical weathering of detrital minerals is at the montmorillonite stage.
