    2019-4-9 · The proportion of monocrystalline grains is higher (74–84%) than the polycrystalline quartz grains (15–17%). The non-undulatory monocrystalline variety (Qn) is more common than undulatory variety (Qu). The plots on a QtFL diagram (figure 4A) show a higher percentage of quartz grains (Qt81F6L12) due to deficiency of feldspar.
