Roundness

Rounded to sub-rounded and sub-angular

Sub-angular to sub-rounded

Sutured Contacts

Rare: only some of the larger quartz grains display sutured contacts

More common than in Tanawal samples

Intra-granular Fractures

More common than in Misri Banda samples

Rare

Strained Quartz

Monocrystalline quartz with undulose extinction occurs insubstantial amounts

Rare: only some of the larger quartz grains show undulose extinction

Polycrystalline Quartz

More abundant than in Misri Banda samples, but very rarely containing more than 2 to 3 sub-grains per grain

Present; but the overall abundance is lower and the number of sub-grains per grain less than Tanawal
