Geological investigation of the Priestly Formation and Snowy Point Gneiss Complex in the Berg Mountains from Terra Nova Bay to Campbell Glacier, Oates Coast, North Victoria Land: GANOVEX VII

As part of the GANOVEX VII Expedition (German Antarctic North Victoria Land Expedition) two research topics were investigated; a) the passage of metasedimentary Priestley Formation into gneisses of Snowy Point Gneiss Complex and the extent and character of the contact between them and b) the occurrence of granulite facies rocks in the gneiss sequence and their relationships to metamorphism and the tectonic history of the gneiss lithodeme.

Field work was concentrated on the Deep Freeze Range between Mt Levick on the Priestley Glacier, Mt Dickason on the Campbell Glacier and Terra Nova Bay. A reconnaissance flight enabled all Priestly Formation outcrops on the east side of the Campbell Glacier to be sampled and to compare with Priestley Formation rocks from west of the Snowy Point Gneiss Complex belt along the eastern Deep Freeze Range. 315 rock samples were collected for dating, petrological and structural analysis and geochemistry.
