Overview: 

Overview TAMARA, a collaborative US-German research program Geology of Southern Victoria Land Interpretation of geophysical and remote sensing data for Lineament mapping Mapping dolerite bodies Studying the structure of Radian lineament

Conclusions: 

Conclusions A combination of satellite imagery and geophysical data is used to map structures on ice covered areas Aeromagnetic results suggest a feeder like body in NW corner of TAMARA area Magnetic anomalies around Skelton Neve can be explained by dolerite sills with dike-roots. The Radian lineament extends toward NW under the ice sheet. Radio-echo sounding detected bedrock undulations around the Portal. The size and frequency of the ‘bumps’ is similar to the surface expression of dolerite dikes
