Ripple marks – Wikipedia
These commonly form in fluvial and aeolian depositional environments, and are a signifier of the lower part of the Lower Flow Regime. Ripple cross-laminae forms when deposition takes place during migration of current or wave ripples. A series of cross-laminae are produced by superimposing migrating ripples.

Combined Current/Wave Ripples
Sets of cross lamination may be formed, bounded by erosive surfaces. Climbing ripples are formed as a result; require net deposition, as in decelerating flows …
