Antarctic literature has provided inadequate research on alternative methods of weathering, such as chemical rock weathering due to a historical predisposition which, favoured mechanical weathering processes in cold environments1. New studies, however, have brought to light the role of water limiting environments and high rock temperatures, which facilitate the potential for chemical weathering to occur1. The overarching aim of this research was to investigate and document chemical weathering of rock samples from selected nunataks in Western Dronning Maud Land, Antarctica. Through the use of weathering profiles, rock samples and environmental data it has been documented that chemical weathering is occurring. The majority of the evidence for this being noted in weathering rinds, precipitates, and in soils (where present).
