WebTurbidites. Turbidites provide a good summary of the ideas we have been talking about, e.g. facies and sedimentary structures related to flows. Turbidites are deposited from slurries of sediment and water in any standing body of water (lakes, oceans). ( photos of turbidites) Turbidity flows start with slope failure in soft sediment. WebSince the Bouma paper of 1962 it has been demonstrated the turbidite deposit is a “member” of an evolutionary trend of vertically associated sediments that accumulate from debris flows, hyperconcentrated to concentrated density flows, and turbidity flows (Mulder & Alexander, 2001).
