Bilingual glossary of geology

A symmetric ripple mark having a sharp, narrow, and relatively straight crest between broad rounded troughs. Oscillatory ripples (also called wave ripples) form on unconsolidated sedimentary substrates affected by the oscillatory flow generated by waves. Current is bidirectional and in an orientation that is perpendicular to the crestlines of the ripples.
