Abstract

Freeze-thaw and wetting-drying experiments with about 90 different Swedish rocks are described. On an average sandstones decompose 11 times faster than granites. The soft sedimentary rocks included in the experiment have produced between 1 100 and 31 000 times more material of grain sizes less than 1 mm than the mean for granites. The observed weathering rate from the freeze-thaw cycles is about 100 times slower than the rate calculated by measuring the height of quartz veins above the surrounding rock in the field
