Rock moisture content in the field and the laboratory and its relationship to mechanical weathering studies
Rock moisture content is a major control of mechanical weathering, particularly freeze‐thaw, and yet almost no data exist from field situations. This study presents moisture content values for rocks, taken from a variety of positions and conditions, in the maritime Antarctic. Additional information...
