Glacial and periglacial history of the southern Prince Charles Mountains, East Antarctica
Field investigations into glacial sediments and landforms in the southern Prince Charles Mountains reveal at least four major phases of deposition. The oldest, which is a thick succession of mud-rich sediments on the summit surfaces, is a potential correlative of the mid-late Cenozoic Pagodroma Grou...
