Mechanical weathering rates on Signy Island, maritime antarctic
Abstract By means of re‐evaluating a number of properties of rock tablets left in the field for varying time periods, an estimation of rock breakdown rates is attained. From data obtained during the last five years, it would appear that rates are very slow, only of the order of 2% mass loss per 100...
