利用滚筒装置进行的实验研究揭示了各种石英的机械耐久性的顺序：细多晶石英>粗多晶石英>单晶石英。已发表的实地研究表明，单晶石英比多晶石英具有更大的生存潜力。这表明，化学稳定性是更重要的比内在的机械耐久性，在确定碎屑颗粒的生存潜力，在其沉积前的历史。
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.
