particle size | Encyclopedia.com

particle size (grain size) The diameter or volume of the grains in a sediment or sedimentary rock.The particle size can be determined by sieving, by measuring the settling velocity, or (for pebbles, boulders, and cobbles) by direct measurement of individual clasts.The smaller particles are normally defined by their volume diameters, i.e. the diameter of a sphere with the same volume as the ...

A cobble is a clast of rock with a particle size of ~2.5 to 10 inches or 6-25 cm, based on the Krumbein phi scale of sedimentology. Cobbles are generally considered to be larger than pebbles (4 to 64 millimetres diameter) and smaller than boulders (greater than 256 millimetres diameter, or generally, 30 cm/1 foot [1 meter is 3 feet]).
