Abstract

Experimental studies using a tumbling barrel apparatus reveal the following sequence of mechanical durabilities for varieties of quartz: finely-polycrystalline quartz > coarsely-polycrystalline quartz > monocrystalline quartz. Published field studies indicate that monocrystalline quartz has a greater survival potential than polycrystalline quartz. This suggests that chemical stability is more important than inherent mechanical durability in determining the survival potential of detrital grains during their predepositional history.
