Ripple marks.

Ripple marks in a sediment are characteristic of deposition of the inorganic materials in shallow water and are caused by forces such as wave-related forces or wind-related forces that leave ripples of sand as typified by the marks seen on beach sand or on the bottom of a shallow stream.

Although this is not a complete list, it is a good introduction to depositional environments. Continental. Transitional. Ripple marks form perpendicular to the wind direction and each ridge is roughly equidistant from the ripple mark on either side. The lack of vegetation at Cavern Point suggests the wind is often very strong, which hinders plant growth, but provides ideal conditions for eolian (wind formed) ripples.

The rock formed in a fast-moving stream is what the presence of ripple marks says about the area where the rock formed.Examples of bed forms include dunes and ripple marks. Sole markings, such as tool marks and flute casts, are grooves eroded on a surface that are preserved by renewed sedimentation. These are often elongated structures and can be used to establish the direction of the flow during deposition. Ripple marks also form in flowing water.

These movements are unequal in time and intensity in opposite directions. The result is asymmetrical ripple marks which usually migrate in the direction of wave travel. Therefore wave-formed ripple marks should be divided into two classes: Symmetrical oscillation ripples and asymmetrical oscillation ripples. This content is PDF only.
