⭐ Core Definition: Subaqueous fans

A subaqueous fan is a fan-shaped deposit formed beneath water (similar to deltas or terrestrial alluvial fans), that is commonly related to glaciers and crater lakes.

Subaqueous fan deposits are generally described as coarse to fine gravel and/or sand, with variable texture and sorting.Underflows (meltwater denser than lake water) tend to produce subaqueous fans with channels and levees. Subaqueous fans can be formed by the influence of glacier movement and by underwater currents typically found at a river delta. The sediment size and composition that makes up the subaqueous fan is dependent on the type of rock that the water flow or glacial ice sheet moves over. Sedimentary structures found in subaqueous fans are heavily dependent on the strength of the water flow.

👉 Subaqueous fans in the context of Strait

A strait is a water body connecting two seas or water basins. The surface water is, for the most part, at the same elevation on both sides and can flow through the strait in either direction, although the topography generally constricts the flow somewhat. In some straits, there is a dominant directional current. Most commonly, the strait is a narrow channel that lies between two land masses. Straits are loci for sediment accumulation, with sand-sized deposits usually occurring on the two strait exits, forming subaqueous fans or deltas. Some straits are not navigable because, for example, they are too narrow or too shallow, or due to the presence of a reef or archipelago.
