1995-1-1  Glacial grinding has traditionally been considered to be the only effective mechanism for the production of loessic silt. For exam- ple, Smalley and Krinsley (1978, p. 63): "Glacial grind- ing is the only natural process which efficiently converts sand-sized quartz particles totally into a silt-sized prod- uct."

Fluvial Comminution and the Production of Loess-Sized

Brazilian quartz sand to simulate comminution in high energy, mixed sediment fluvial environments. Results show that the sand is quickly reduced to silt (16 hours at 155 rpm) by a sequence of edge chipping, partial cracking, splitting and crushing. Comminution is most rapid at higher rotation speeds but significantly occurs even at the lowest

Aeolian abrasion of quartz particles and the production of

Summary Experimental abrasion of quartz sand in an air stream shows that particles with initially high angularity are progressively rounded by the chipping of edges and corners. Grains closely resemble dune sand grains from deserts with respect to rounding and microscopic surface textures after 48 hours of abrasion. Results show an initially high weight loss from the original grains (primarily

Thus, silty sands are more compact where quartz is the dominant mineral in the sand and silt fraction and forms a significant proportion of the the stability of these systems is very weak and compaction by wheels or other actions can in return produce a dense structure.

Crushing and Screening

Where dry screening was accepted in the past, washing and scrubbing are now required to produce a silt free product, free from contaminants. A typical rinsing set-up would be used when the material does not require scrubbing, only rinsing to remove small particles of silt and fines to produce a clean end product.

On the formation of desert loess Quaternary Research

The processes that produce fine mineral aerosols are distinct from those that produce quartz-rich silt and are dominated by the impact of saltating sand particles on fine-grained soils and sediments (Kok et al., Reference Kok, Eric, Timothy and Diana Bou 2012 and references therein). Therefore, coarse silt is “dust,” but most “dust” is
