A turbidity current is most typically an underwater current of usually rapidly moving, sediment-laden water moving down a slope; although current research indicates that water-saturated sediment may b
Turbidites are deposited in the deep ocean troughs below the continental shelf, or similar structures in deep lakes, by turbidity currents which slide down the slopes.

Once an oceanic turbidity current reaches the calmer waters of the flatter area of the abyssal plain (main oceanic floor), the particles borne by the current settle out of the water column. The sedimentary deposit of a turbidity current is called a…
