Wave-formed ripple Wave-formed ripple In sedimentology, wave-formed ripples or wave-formed ripple marks are a feature of sediments (sandstones, limestones, siltstones) and dunes. These ripple marks are often characterised (and thus distinguished from current ripples) by symmetric cross sections and long relatively straight crests, which may commonly bifurcate. Commonly, these crests can be truncated by subsequent flows. Their wavelength (periodicity) depends on the sediment grain size, water depth and water-particle orbits in the waves. On tidal flats the pattern of wave-formed ripples may be complicated, as a product of changing depth and wind and tidal runoff directions. Symmetrical ripples are commonly found in
The Crests & The Crests", producing a single for United Artists in 1962, two singles for Cameo Records in 1963-64, a single for APT Records in 1965, a single for Scepter Records in 1965, and three singles for the Parkway label in 1966. James Ancrum then took over the lead, recording "Guilty" in January 1962 and charting only to #123. The group went back to touring when their 1963 Selma side "Did I Remember?" flopped. A 1964 sequel to "16 Candles", "You Blew Out The Candles", also was not successful. In 1965, J.T. Carter and Mel Tillison signed with Decca Records and
