Geology of the Belgica Mountains

P(論文) The Belgica Mountains lie at the east end of the East Queen Maud Land, located at 72°18'S-72°43'S latitude and 30°57'E-31°20'E longitude. Crystalline basement rocks of this area are the Belgica group which is divided into the Belgica upper formation and the Belgica lower fo...
