Prospecting for mineralization using glacially-derived sediments, Anvers Island, Antarctic Peninsula
Two samples of fine glacially-derived sediment were taken along the ice front on Gamage Point in the Arthur Harbor area of Anvers Island, Antarctic Peninsula. The samples were sieve separated, run through heavy liquid, and examined in thin section and polished surface. The work was done to determine...
