Experimental studies show that changes in wettability of mineralgrain surface affects seriously the dispersive stability of the mineral pulp as a suspension system.
By crushing an inclusion in a mineralgrain on a particularly-made stage under a microscope, the gaseous phase in the inclusion is released and can be observed and detected.
These rocks are lack of foliation and resulted from the brittle fragmentation of mineral grains with rotation of grain fragments accompanied by fractional grain boundary sliding and dilatancy.
