Current ripple marks
Silver stamp marks, sometimes known as hallmarks or makers marks, give information about products made of silver. Marks on items like jewelry and flatware can indicate the purity of the silver, who made it and where.Recognizing asymmetric ripples tells us immediately where the flow was directed. We can, for example, reconstruct the direction of a river, or a marine current, or the dominant wind in sandstone that deposited millions of years ago. Symmetric ripple marks formed by waves in Permian rocks from Nomgon, Mongolia.

They are form perpendicular to the wind direction and each ridge is roughly equidistant from the ripple mark on either side.Defining ripple cross-laminae and asymmetric ripples. 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. The down-current slope is the angle of repose, which depends on the shape of the sediment.These commonly form in fluvial and aeolian …We find ripple marks in sedimentary rocks, and we also find them formed by current action in nature.
