Cross cutting relations are used in relative dating because you can see which layers were deposited before or after the fault occured the same way, when a fault cuts througha rock, or when magma intrudes and crystallizes, we can assume that the fault or intrusion is younger than the rocks . Associated with both relative and absolute dating relative dating states that geologic features such as faults and igneous intrusions, which cut.
