Identifying and classifying rocks can ...Grain size classifications of detrital sedimentary rock are, from smallest to largest: clay, silt, sand, pebble, cobble, and boulder. Grain sorting describes the uniformity of grain size in the rock.Silt is a size term used for material that's smaller than sand (generally 0.1 millimeter) but larger than clay (around 0.004 mm). The silt in this siltstone is unusually pure, containing very little sand or clay. The absence of clay matrix makes siltstone soft and crumbly, even though this specimen is many millions of years old.
