Turbidite
From CreationWiki, the encyclopedia of creation science
Turbidites are sedimentary rocks formations that result from turbidity currents. Turbidity currents are essentially underwater avalanches or landslides of sand or mud. The debris deposited as a result of these subaqueous flows typically forms a graded bed of sediment built up at the base of a submarine slope. They are sea-floor deposit frequently formed by massive slope failures where rivers have deposited large deltas. These slopes fail in response to earthquake shaking or excessive sedimentation load. The temporal correlation of turbidite occurrence for some deltas of the Pacific Northwest suggests that these deposits have been formed by earthquakes.
Turbidity currents are thought responsible for distributing vast amounts of clastic sediment.
