Abstract:

Based on the analysis of REE in the sediments from the Great Wall Bay, Antarctica, in this paper the source of sediments is discussed. It was thought that the concentration, distribution model and character parameters of the REE in the sediments are similar to those of the volcanic rock exposed on the Feldes Peninsula; that is, the abundance of the total REE of each sample is not high; the samples have the similar REE distribution patterns which are slightly enriched in LREE; REE character parameters of the sediments indicate both characteristics of island-arc tholeiite and island-arc calc-alkaline basalt. Thus the weathering products of basement rock on the peninsula should be the main source of the sediments.
