n: 1. a body of coarse, poorly sorted sediments formed by the coalescence of alluvial or detrital fans along the flanks of a mountain range. 2. a similar body of turbidite sediments formed by the coalescence of submarine debris fans along the base of the continental slope.

n: a type of rock consisting of thinly bedded sandstone and shale, thought to be the result of the action of turbidity currents;a succession of turbidites originating in marine depositional basins, usually near the base of the continental slope. Flysch deposites are especially common in the Alpine region of Europe.

n: a characteristic sedimentary deposit of the continental rise, formed by a turbidity current and composed of clay, silt, and gravel with the clay on top. See turbidity current.

n: a dense mass of sediment-laden water that flows down the continental slope, typically through a submarine canyon. It carries clay, silt, and gravel quickly and turbulently downslope in a narrow tongue. When it reaches the more gradual slope of the continental rise, its energy is dissipated rapidly by friction, and the sediments settle out, largest particles first, to form a thick graded bed called a turbidite.
