Quantitative estimation of cryogenic weathering energy
Abstract Experiments to measure the energy released by the cryogenic weathering of sandstone and shale are described. The energy released by fracturing is thought to be proportional to the importance of new surfaces appearing in the rock at the time of disintegration. The specific surfaces of sample...
