"How has the earth evolved, and how has the interior structure formed since its origin as a planet?" This is a simple but fundamental question we raise as geoscientists, and in order to get an answer to this, geoscientific investigations have been carried out all over the world.
On the basis of the geoscientific work performed by the Japanese Antarctic Research Expedition (JARE) , it has been turned out that the region including Dronning Maud Land and Enderby Land is an ideal field from which we can find an answer to the question above, because the continental crust in this region is composed of Archean to Paleozoic ages for nearly 3500 million years. The fundamental idea of our research is to clarify the structure and evolution of the lithosphere by means of a variety of methods and techniques in geoscience. Moreover, recent fluctuation of continental ice sheet is also considered based on the glacial landscape, sediments and features of the continental shelf, etc.
