There are bands of moraine extending for 20km which comprises of complex composition, including a few of gravel of sedimentary rocks which were markedly different from the basement rocks of high-grade gneiss on the southeast side of the Vestfold Hills, East Antarctica. According by the direction of glacier flows the source of the gravel is in the southeast of Vestfold Hills under the glacier. Eight samples of LA-ICP-MS detrital zircon populations analysis indicate that most of the age of U-Pb zircon ages are between 2410-2600Ma, and 3340-3500Ma, without the metamorphose age of 1000Ma and 500Ma. This not only indicates that in the southeast of Vestfold Hills exists an Early-Archaean continent plate and also means that the source of clastic rocks is from a single provenance.
