Glacial comminution of quartz sand grains and the

1995-1-1  Abrasion predominantly affects the boulders and cobbles, producing mainly silt- sized particles together with a small amount of sand. These results suggest that abrasive wear of cobbles and boulders may be responsible for the production of silt- sized particles while the crushing of gravel may produce sand-sized particles.

Silt-sized quartz particles: a proposed source

1974-12-1  When sufficient- ly large forces are exerted, the reduction of the quartz-sand grains along cracks right across them will occur simultaneously (crushing) and in this way smaller sand as well as silt particles may originate (Moss, 1966).

Micromechanics of quartz sand breakage in a fractal

2014-4-15  The sand-to-silt size reduction pathway in quartz possesses fractal properties (in sorting, maximum particle size, fractal dimension, and modal size distribution). Light transmission microscopy examination of sand- and silt-sized quartz samples before crushing revealed evidence of surface imperfections and internal planes of varied taxonomy.

PROCESSES OF QUARTZ FRACTURE IN NATURE AND

1979-1-1  The north European glaciers were deforming old shield rocks and releasing quartz particles from them, some of these particles escaped further fracture and remained as sand; however when one was trapped in a crushing situation it was fractured completely and a silt sized mode produced.

Controls on quartz silt formation by crystalline defects

2006-2-24  Experiments conducted on unweathered sand-sized vein quartz produced little silt, while use of sand from a sedimentary deposit, Leighton Buzzard sand, produced plentiful silt. Experimental results suggest that there is an internal mineralogical control on the formation of quartz silt particles.

Particle crushing in hydrate-bearing sands

2020-7-1  The depressurization of natural hydrate deposits to produce methane gas can increase the effective stress in hydrate-bearing sediments, which may induce sand particle crushing. Sand crushing may become detrimental to gas production, because the breakage of sand particles can cause sediment contraction, reduction in permeability, and the generation of finer particles exacerbating solids migration and sand

Silt-sized quartz particles: a proposed source

1974-12-1  The origin of quartz-silt particles is attributed especially to the development and the breakdown of the cracked, marginal parts of sand-sized grains and particles. Generally the breakdown of these cracked grain parts will take place subsequently to their genesis, but these processes may partly overlap one another.

Glacial comminution of quartz sand grains and the

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. This idea has been strengthened by the apparent close association between present or former glacierised regions and major global
