Gravel is rock that is of a certain particle size range. In geology, gravel is any loose rock that is larger than two millimeters (mm) (about 1/12 an inch) in its longest dimension but no more than 63 millimeters (about 2.5 inches). The natural erosion of larger rocks has led to the formation of many gravel deposits. In addition, gravel is now produced by crushing rocks mechanically.
Gravels are rock or mineral fragments with an average particle size greater than 2 mm and less than 60 mm (Poesen and Lavee 1994)pared with soils in other regions of China, soils in the northern Tibetan plateau have many gravels due to their late geological formation and coarser soil fractions (Du et al. 2017; Wang et al. 2012).The presence of gravels …

Sediments Classification Based On Grain Size. Sediments are solid fragments of inorganic or organic material that come from the weathering of rock and soil erosion, and are carried and deposited by wind, water, or ice. They range in size from large blocks to microscopic particles. Figure 6.39 shows the technical definition of sediment particles.
Particle size Particle size, also called grain size, refers to the diameter of individual grains of sediment, or the lithified particles in clastic rocks. Granular material can range from very small colloidal particles, through clay, silt, sand, and gravel, to boulders. four gross divisions of the size scale are easy to use: clay, silt, sand ...
Particle sizes in coarse gravel are greater than 20 mm but not greater than 63 mm. As you can see, this classification disregards whether gravel is made of crushed rocks or is a naturally occurring substance. Only the sizes are considered. Gravel/Crushed Stones Size Chart
