What is relative and absolute dating

Explanations: A – folded rock strata cut by a thrust fault; B – large intrusion (cutting through A); C – erosional angular unconformity (cutting off A & B) on which rock strata were deposited; D – volcanic dyke (cutting through A, B & C); E – even younger rock strata (overlying C & D); F – normal fault (cutting through A, B, C & E).

The principle of cross-cutting relationships pertains to the formation of faults and the age of the sequences through which they cut.

This is because it is not possible for a younger layer to slip beneath a layer previously deposited.

The only disturbance that the layers experience is bioturbation, in which animals and/or plants move things in the layers.

These strata make up much of the famous prominent rock formations in widely spaced protected areas such as Capitol Reef National Park and Canyonlands National Park.

He also found that certain animals were in only certain layers and that they were in the same layers all across England.

Due to that discovery, Smith was able to recognize the order that the rocks were formed.

however, this process is not enough to allow the layers to change their positions.

This principle allows sedimentary layers to be viewed as a form of vertical time line, a partial or complete record of the time elapsed from deposition of the lowest layer to deposition of the highest bed.

Observation of modern marine and non-marine sediments in a wide variety of environments supports this generalization (although cross-bedding is inclined, the overall orientation of cross-bedded units is horizontal).
