Wave Ripple Lamination
Specifically the laminae show transport in 2 directions and the ripple crests if preserved are.
Wave ripple lamination. Ripples formed by a combination of wave action and unidirectional flow wave ripple cross lamination is characterized by a variety of distinctive features including. Interference ripple sets silurian clam bank formation port au port peninsula nfld. The cross lamination produced by wave ripples is distinct from that produced by current ripples. The down current slope is the angle of repose which depends on the shape of the sediment these commonly form in fluvial and aeolian depositional environments and are a.
Wave ripple cross lamination the form of cross lamination see cross stratification produced by the migration of wave generated ripples or combined flow ripples i e. However the individual ripple cross sections are symmetric characteristic of wave action. These wave ripple cross laminations are less clearly symmetric. Ii small superimposed sets of angle of repose cross lamination where the thickest and most prevalent sets have onshore dips and the thinner subsidiary sets dip offshore.
Defining ripple cross laminae and asymmetric ripples. Samples from four adjacent beaches bluewater georgina wendake and wym bolwood have been collected over several years. Bimodal cross lamination in wave ripple form sets location the wave ripple structures were obtained from the tide less storm wave dominated sandy shoreface located in georgian bay ontario canada figure 1. Wave ripple cross lamination formed in a sandy lacustrine shoreface in the canadian great lakes is characterized by i small randomly superimposed sets of angle of repose cross lamination with strongly bimodal dips.
Current ripple marks unidirectional ripples or asymmetrical ripple marks are asymmetrical in profile with a gentle up current slope and a steeper down current slope.
