| Definitionskos:definition | Ribbon marks are elongate mounded filaments of sand (and/or gravel), mostly regularly spaced, with parallel to slightly sinuous plan-form. They may show gentle curvature in parallel with the flow pattern, and merge into or diverge from broad sand sheets. Most of those reported are large-scale bedforms (width 10–100 m, length 5–50 km), although smaller-scale units (width of a few meters) have been referred to as narrow ribbons, sand streamers and sand streaks. They are high-velocity bedforms (generally 0.7–1.5 m/s) that involve winnowing and erosion of a sand or sand and gravel substrate coupled with redeposition of the material into elongate ribbon mound (Stow et al., 2009). |
