Topographical and geological surveys at Carapace Nunatak, Allan Nunatak and the Coombs Hills, Victoria Land, Antarctica
Listed in NASA Earthdata CMR
A detailed geological study of Carapace Nunatak, Allan Nunatak and the Coombs Hills at the head of the Mawson and Mackay Glaciers was conducted.
Description
The whole are was systematically covered with three main groups of rocks seen, including 1) Beacon sandstones, 2) Mawson tillite and 3) dolerites and basalts. A detailed topographical survey was made concurrently.
From a chained baseline in Trudge Valley, a triangulation net was extended over the Allan Nunatak to Carapace Nunatak and the Coombs Hills. This should provide adequate photocontrol for mapping to a scale of 1:20,000.
