WebApr 1, 2012 · Climbing‐ripple cross‐lamination is most commonly deposited by turbidity currents when suspended load fallout and bedload transport occur contemporaneously. The angle of ripple climb reflects the ratio of suspended load fallout and bedload sedimentation rates, allowing for the calculation of the flow properties and durations of turbidity currents. WebC limbing - ripple cross-lamination, Sorby’s (1859, 1908) ripple-drift bedding, is an important and significant sedimentary structure resulting from the action of unidirectional currents. The importance of the structure lies in its worldwide distribution and frequent occurrence in such diverse sediments as river channel and levee sands and in ...
