Climbing ripple lamination on a rock
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 ... WebConvolute laminations are deformational structures developed in rapidly deposited fine-grained sands and silts, and commonly associated to water-escape structures and …

WebClimbing-ripple cross-lamination in the New Zealand study area was deposited both outside of and within channels at an inferred break in slope, where flows were decelerating and expanding. In the South Africa study area, climbing-ripple cross-lamination was deposited due to a loss of flow confinement. In the Magnolia study area, an abrupt ... WebClimbing ripples in Quaternary lake silts in the glaciated part of Nebraska are defined by continuous laminae over some of the ripple systems, but more commonly, by laminae …
WebIf there is net deposition of sediment, the ripples leave behind distinctive dipping layers between two erosional surfaces that can be preserved in the rock record. These layers slope downstream and are one type of cross lamination. A sketch of a ripple or dune like the one in lecture WebA distinctive feature of the tuffs in this area is the very well developed climbing-ripple lamination (Plate I, Fig. 2). This structure is formed by the downcurrent migration of small ripples...

WebThe presence of climbing ripple lamination indicates rapid deposition from a sediment-laden flow. Upward transition from planar lamination to current ripple lamination is indicative of flow deceleration. ...
