An airborne gravity survey south of the Prince Charles Mountains, East Antarctica

Abstract

The Lambert Glacier - Amery Ice Shelf in East Antarctica is a north-northeast trending graben, which is host to the largest glacier in the world. While the present configuration of this structure suggests a failed rift, some workers have suggested the Lambert region also preserves evidence of an earlier Cambrian suture between at least two Pre-Cambrian blocks that collided during the assembly of Gondwana. Very little previous gravity data exists in the Prince Charles Mountains and no previous gravity data has been collected south of this region. A joint Australian / German expedition under the banner of PCMEGA (Prince Charles Mountains Expedition of Germany and Australia) was established to ..
