Frost action and hydration as rock weathering mechanisms on schist: a laboratory study

Auteur :
FAHEY, B. D.

Description :
The A. shows, under controlled experimental conditions, aggregates of fresh and partly-weathered schist and fresh pre-cut schist blocks submitted to 500 accelerated freeze-thaw and hydration-dehydration cycles. Although hydration effects were not as effective as frost action in causing particle size reduction in aggregates, the two mechanisms may well reinforce one another in periglacial environments, enhancing the ability of these areas to serve as source regions for loess.
