Geochemical and Glacio-geomorphic Implications of Basalt Weathering in the Queen Maud Mountains, Antarctica
Summary. The weathering of a suite of basalt clasts. that have been transported by mass wasting downslope in the Cumulus Hills region of the Queen Maud Mountains. Antarctica. is examined from both geochemical and glacio-geomorphic viewpoints. Chemical weathering. predominantly oxidation and hydratio...
