Rock Moisture Content and Frost Weathering under Natural and Experimental Conditions: A Comparative Discussion

Abstract

Frost weathering simulation studies provide a useful means of gaining insights into the nature of frost-weathering phenomena. If such studies are to be of value, however, experimental conditions should approximate those in nature. Experimental moisture regimes tend to promote degrees of saturation which exceed those likely to be attained naturally. The possibility therefore exists that experiments may exaggerate natural weathering effects. Acquisition of data on moisture contents of rocks in cold environments as a basis for freeze-thaw experiments is necessary.
