abyssal cone
Quick Summary
An abyssal cone is a geological feature formed by the accumulation of terrigenous sediment in the deep ocean. This sediment is transported from land by rivers and wind, often carried down continental slopes by turbidity currents. These currents create deposits known as turbidites, which build up into cone-shaped features called abyssal cones, typically found below major river deltas. Abyssal cones are a key component in the formation of abyssal plains, which are flat, sediment-covered areas of the ocean floor where sediment supply is abundant.12
