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. WebRip-up clasts are gravel-size pieces of clay or mud created when an erosive current flows over a bed of clay or mud and removes pieces of clayey sediment, and transports them some distance.Because clayey sediments can be quite cohesive, even when freshly deposited, large clasts of clayey sediment can be ripped up, transported and …
