An aerogeophysical survey south of the Prince Charles Mountains, East Antarctica

Abstract

Previous interpretations of existing Russian data have allowed distinction of major geological blocks an magnetic trends in the Prince Charles Mountains (PCMs), which can be correlated with the known geology. However, there is extremely poor outcrop south of the PCMs region. The objective of our investigation was to extend the magnetic coverage to the south to assist in understanding the Lambert / Amery rift system in its most southerly part and to look for its possible extension beneath the East Antarctic Ice Sheet. This paper presents the methodology, data and preliminary interpretations of the airborne magnetic data acquired as part of the Prince Charles Mountains Expedition of Germany an..
