unconformity

A fourth unconformity was created by a period of erosion.

These deposits occur below, across and immediately above the unconformity.

The unconformity is clearly visible in the face of the waterfall.

The unconformity represents a gap in the record of geological time.

However, an unconformity in the sediment sequence might make this analysis difficult.

The relief at this unconformity is small, being about 10 m (35 ft).

Although they have a wide range in age, no unconformity has been found between two successive formations.

An unconformity represents time during which no sediments were preserved in the region.

This created a major unconformity that represents 460 million years of lost geologic history in the area.

A second unconformity was created after the Permian sea retreated.

A major unconformity separates it from the lower Tippecanoe sequence.

Another period of erosion returned, creating a third unconformity.

This event is synchronous with the major unconformity above.

However interdigitation is found as if to testify against an unconformity.

The gap in the rock record has been called The Great Unconformity.

An unconformity marks the top of this formation.

Paleomagnetic data suggest that this unconformity represents a major time break.

An angular unconformity (an uneven gap in the geologic record) followed.

A period of erosion then ensued, creating a break in the geologic record called an unconformity.

The mountain is composed of a geologic unconformity between two separate rock formations.

This large unconformity indicates a period of erosion between two periods of deposition.

It is the site of the Great Unconformity.

They lie upon an angular unconformity cuts across pre-basin strata.

The Permian sea retreated, which exposed the land to a long period of erosion and thus created a second unconformity.

There is an unconformity at the Pliocene base.
