ripple marks

Ripple marks and other features indicate it was close to the shore.

On the stream bed ripple marks may be seen.

He sat on white sand that reached beyond sight in graceful ripple marks.

In some examples it has a corrugated surface of ripple marks.

Ripple marks in this rock clearly indicate its shallow water origin.

Ripple marks created by the sea's wave action are visible in the shale.

Ripple marks are common in the upper members of this dark brown thin-bedded layer.

Ripple marks and cross bedding show that shallow water was also commonly present.

Ripple marks are less common but they are evidence of deposition in shallow water.

Ripple marks and mud cracks occur throughout the series.

There are also immense potholes and ripple marks, much larger than those found on ordinary rivers.

Ripple marks also form in flowing water.

Current ripple marks - will have the short side of the ripple pointing down stream.

Symmetrical ripple marks - flow is perpendicular to the ridge crest.

Asymmetrical ripple marks - These are created by a one way current, for example in a river, or the wind in a desert.

Ripple marks are seldom found, but do support interpretation as a shallow marine depositional environment.

Ripple marks can be found in much of the rock; they would have formed mostly in shallow water with gentle waves.

Ripple marks are stretched transversely to the diluvial floods.

There are two types of ripple marks:

The sinusoidal high points of the ripple marks may lend itself to the formation of the trackways.

Sheets of ripple marks can be seen on some of the strata, confirming the shallow-sea environment.

The giant current ripple marks are important depositional forms in diluvial plain and mountain scablands.

Sapwood is white with distinct ripple marks; the heartwood is red-brown.

The characteristic ripple marks are retained.

This creates ripple marks with pointed crests and rounded troughs, which aren't inclined more to a certain direction.
