Block disintegration is "the splitting of rocks along the joints into blocks." http://en.wikipedia.org/wiki/Weathering "Granular Disintegration: Chemical weathering generates clays. Some clays swell upon being wetted. Iron oxides also swell when hydrated. This swelling can pry apart the crystals in coarse-grained rocks. Granular disintegration of igneous and metamorphic rocks like granite, diorite, and gneiss yields masses of slightly weathered grains termed "grus." Granular disintegration of sandstone simply yields sand." http://myweb.cwpost.liu.edu/vdivener/notes/weathering_effects.htm
