Abstract:
Sample inventory data related to a field campaign of approximately 10 weeks, carried out during 2007-2008. The primary focus was sample collection, with the rest of the time being used for mapping. All of the samples taken were of rocks that were found cropping out as nunataks. The investigation took place entirely within the the Dronning-Maud Land area of East Antarctica (Norwegian Sector).

| Data Collection: | Field work was carried out between 01 December 2007 and 05 February 2008 with 58 days in the deep field . Horst Marschall accompanied by a field guide (Sune Tamm-Buckle, Field GA, Halley Winter GA 2007) started from the Norwegian station Troll and travelled 1, 480 km on Skidoo. Outcrop conditions in the entire field area were superb, with 300 − 900m high walls of vertical outcrop of metamorphic sedimentary and magmatic sequences. Weathering is restricted to the tops of the nunataks and most outcrops are accessible on foot, after driving to the foot of the nunataks by skidoo. 208 samples were taken and stored into 18 rock boxes (total weight 500 kg), which arrived in the UK in late April 2008. |
