Figure F3. Schematic representation of internal structure of facies within turbidites recovered during Leg 178 compared with Piper's (1978) descriptive scheme for muddy turbidites. The three facies recognized are essentially formed by repetitive turbidite sequences that form relatively thick depositional units. Intensity of bioturbation, amount of ice-rafted debris, and thickness of hemipelagic division at bed tops depends on the recurrence interval of turbidity currents.
