The "Fildes Peninsula group" tertiary volcanic rocks analysed were outcropped near the Chinese Great Wall Antarctic Station. The trace element compositions of the rocks were determined by instrumental neutron activation analysis. The basalts from Fildes Peninsula are characterized by their lower contents of Ti
Zr
Ni
Co and Cr and higher of Cs
Sr
Rb
Ba
Th and Ta in comparison with N-type mid-ocean ridge basalts (N-MORB). They have extremely similar REE distribution patterns of rich LREE and no Eu anomalies.(La/Yb)CN ratios vary from 2.42 to 4.57. All these characteristics show that the basalts from Fildes Peninsula can be considered as the products of island arc volcanism.
