Filling the gap between the GIGAMAP and the GNS maps in Victoria Land, Antarctica: geological mapping in the Convoy Range
In the austral summer 2017/18, in the framework of the 33rd ItaliAntatyide Expedition, a three person team performed geological and geological-glacial field mapping in the Convoy Range (Victoria Land, Antarctica), at the scale 1/250’000. Activity was heli-supported, starting from the Italian base in...
