Diagram showing the evolution of sustained sediment-laden turbulent flows with extrabasinal-derived bedload when entering a marine or lacustrine basin. Bedload deposits (facies B1, B2 and B3) are composed of passively dragged materials inherited form the original discharge, and are typical of proximal areas. Suspended load deposits (facies S1, S2 and S3) accumulate by the collapse of suspended materials due to a decrease in flow capacity. Lofting deposits (facies L) accumulate from density reversal plumes in saline basins. In freshwater lakes lofting is not possible, and shales accumulate as fallout deposits (facies S4)
