Ripple marks are formed due to the presence of waves of wind or water flowing above the surface of sand. In an area of dry sand, wind picks up the small particles up in the air. Due to gravity, these small particles will fall back to the desert floor. This continuous process of lifting and falling of sand particles eventually form the ripple ...

hexagonal cross-ripple marks: see interference ripple marks, tadpole nests. hiatus: discontinuity of sedimentation, stratigraphic gap. hieroglyph: old name for sole marking. horizontal lamination: the term should be used only in Modern and Recent sediments. In Anciet sediments, use plane-parallel lamination, bed-parallel flat lamination.

When a wind or water current flows across loose sand, the sand is dragged along the bottom and frequently is piled up to form ripples and dunes.

Image 143200845.Ripple marks are small ridges, generally less than one inch high and 2 to 8 inches wide. The ridges are developed by moving water and form perpendicular to the direction of water movement. If the profiles of the ripple marks are symmetrical, they are caused by waves; if the profiles are asymmetrical, they are caused by currents.Ripple marks are one of the commonest features of sedimentary rocks, both in recent and ancient sediments. The shape and size of ripples vary considerably. The crests usually run parallel to each other or may anastomose partially. In transverse section they may be symmetrical or asymmetrical in shape.
