WebThe division of soil fractions purely on the basis of grain size can be shown as this. Soil particles of size greater than 300 mm are called boulders. particles between 80 mm and 300 mm are called cobbles. Gravel is defined between 80 mm to 4.75 mm. Sand ranges from 0.075 mm to 4.75 mm. Silts particles have size between 0.075 mm and 0.002 mm Grain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks. The term may also be applied to other granular materials. This is different from the crystallite size, which refers to the size of a single crystal inside a particle or grain. A single grain can be composed of several crystals. Granular material can range from very small colloidal particles, through clay, silt, sand, gravel, and cobbles, to boulders.
