Truncated Previous HitWaveNext Hit-Ripple Laminae: NOTES

Charles V. Campbell


A common but seldom identified sedimentary structure which occurs in a variety of nearshore deposits is truncated Previous HitwaveNext Hit-ripple laminae. This structure consists of sets of parallel laminae that were deposited conformably with the original Previous HitwaveNext Hit-rippled surfaces but were partly eroded prior to deposition of the next set of Previous HitwaveNext Hit-ripple laminae. Ripple wavelengths vary from 10 cm to 10 m and ripple indices from 4 to 17. Small-scale truncated Previous HitwaveNext Hit-ripple laminae differ from the large-scale form only in size. A satisfactory mechanism for formation of the large-scale Previous HitwaveTop ripples is unknown.
