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.

Relative dating is the science of determining the relative order of past events (i.e., the age of an object in comparison to another), without necessarily determining their absolute age (i.e. In geology, rock or superficial deposits, fossils and lithologies can be used to correlate one stratigraphic column with another.

Finding the key bed in these situations may help determine whether the fault is a normal fault or a thrust fault.

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.

There are a number of different types of intrusions, including stocks, laccoliths, batholiths, sills and dikes.

Cross-cutting relations can be used to determine the relative ages of rock strata and other geological structures.Geologists still use the following principles today as a means to provide information about geologic history and the timing of geologic events.
