Igneous rock - Granular, Magma, Crystals: The general grain size ordinarily is taken as the average diameter of dominant grains in the rock; for the pegmatites, which are special rocks with extremely large crystals, it can refer to the maximum exposed dimensions of dominant grains. Most aphanitic rocks are characterized by mineral grains less than 0.3 millimetre (0.01 inch) in diameter, and ... Small pieces of rock are called sediment, although sediment is found in a wide range of sizes. Sediment is created from the weathering and erosion of large rocks, as well as from other natural and unnatural processes.

For sedimentary rocks, the broad categories of sediment size are coarse (greater than 2 millimetres, or 0.08 inch), medium (between 2 and 1 / 16 millimetres), and fine (under 1 / 16 millimetre). The latter includes silt and clay, which both have a size indistinguishable by the human eye and are also termed dust.
