Glacial comminution of quartz sand grains and the ...
Abstract Traditional views have attributed the formation of loess-sized quartz silt particles to glacial processes. Glacial grinding was considered to be the only mechanism capable of producing loessic silt in the quantities necessary for the formation of loess deposits.

The particle size distribution (PSD) before crushing is representative of the poorly-graded quartz Ham River sand and is compared with the grading used by Coop and Lee (1993) in Fig. 3. The single-particle crushing behaviour of the quartz particles of different sands, specifically Ham River sand and Aio sand, is assumed to be similar here.

What is Sand - Overview and Geology
By far the most common mineral in sand is quartz. Hence, the term "sand" without qualification is imagined to be composed of quartz mostly. However, sand is a natural mixture which means that it is never pure. By no means can one say that quartz and sand are the same thing. Consolidated sand is a rock type known as sandstone.

The controls operating in this size range are probably the critical concentration of `Moss' defects in the quartz particles. Moss postulated the formation of specific crystal defects in the quartz formed in granites. These affect sand formation and it is possible that they also control the mode size of silt particles.
