Convolute bedding occurs in both marine and nonmarine sediments of many environmental types. Although essentially syndepositional, its development generally lags behind deposition to a greater or lesser degree. Convolute laminations found in turbidite deposits are ascribed to the forces known to exist in turbidity currents. Convolutions are a fossil record of the forces (current action, loading, sudden regular releases of pressure) acting on a laminated bed during sedimentation. In addition to their origin and characteristics, their directional significance is also discussed.
