Figure F5. Ternary diagram to illustrate classification of sediment texture used during Expedition 313 (modified from Shepard, 1954). Symbols in Shepard diagram are the same as in Figure F4. Classification can be adapted to include modifiers (e.g., glauconite) and different grain sizes (e.g., gravel). Sediment with components of clay, silt, and sand (i.e., the center of the triangle) are either muddy sand or sandy mud.
