Subaqueous fan
From Infogalactic: the planetary knowledge core
A subaqueous fan is a fan-shaped deposit formed beneath water (similar to deltas or terrestrial alluvial fans), and are commonly related to glaciers[1] and crater lakes.[2]
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)tends to produce subaqueous fans with channels and levees.[3]
