WebIf you were to find a sedimentary rock, you can conclude that the lower layers are older than the higher ones and that if there was an igneous intrusion (which is just a layer of igneous rock going through the sedimentary rock), you can conclude that is younger because of the law of crosscutting relationships.

The dikes extend out from the Spanish Peaks as a center to a distance of 25 miles or more. … WebSimply stated, each bed in a sequence of sedimentary rocks (or layered volcanic rocks) is younger than the bed below it and older than the bed above it. This law follows two basic assumptions: (1) the beds were originally deposited near horizontal, and (2) the beds were not overturned after their deposition.
