Abstract. Submarine photography reveals that ripple marks are common in deep water in the sea. Current ripple marks have been found at a depth of 792 feet, and ripple marks which appear to be due to oscillation have been found at 4,500 feet. Water movement competent to move sediment must extend to these depths.current crescents: crescent marks. current lamination: lamination produced by a tractive current. current lineation: alignment of grains or other objects parallel to a current. cuspate ripple marks: see under linguoid. cut-off: erosional event that leaves a segment of a fluvial channel isolated from the main course. Apr 25, 2021 · What do ripple marks show? Ripple marks are sedimentary structures and indicate agitation by water (current or waves) or wind. Ripple marks are ridges of sediment that form in response to wind blowing along a layer of sediment. The symmetry of water-current ripple marks indicate whether they were formed by gentle waves or faster water currents. Ripple marks. The troughs and ridges of fossilized ripple marks in sandstone and siltstones are hardened versions of the short-lived ripples in the loose sand of a modern-day stream, lake, sea, or sand dune. Ripples may be made by …Ripple marks: Ripple marks are small-scale sedimentary structures that are formed by the action of water or wind. They can provide information about the direction and intensity of sediment transport, as well as the flow conditions of the water or wind.

Symmetrical ripple marks are most commonly found in sandstones from shallow marine environments.
