A similar situation with igneous rocks occurs when xenoliths are found.

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