Classify Sand, Silt, and Clay With This Diagram

A ternary diagram is used to translate a sediment's proportion of the three different classes of grain size—sand, silt, and clay—into a soil description. To the geologist, sand is material with grain sizes between 2 millimeters and 1/16th millimeter; silt is 1/16th to 1/256th millimeter; clay is everything smaller than that (they are divisions of the Wentworth scale ).
