original: In geology, when an igneous intrusion cuts across a formation of sedimentary rock, it can be determined that the igneous intrusion is younger than the sedimentary rock.
simplifications: When an igneous intrusion cuts across a formation of sedimentary rock, it can be determined that the igneous intrusion is younger than the sedimentary rock. In geology, when there is an igneous intrusion layer in a formation of sedimentary rock, it can be determined that the igneous intrusion is younger than the sedimentary rock. A plutonic formation can cut across sedimentary rock. It means the plutonic formation is younger. In geology, when an igneous intrusion cuts across a formation of sedimentary rock, the igneous intrusion is younger than the sedimentary rock. When an igneous intrusion cuts across a formation of sedimentary rock, it means the igneous intrusion is younger than the sedimentary rock. When an igneous rock cuts across a sedimentary rock, the igneous rock is younger than the sedimentary rock. In geology, when igneous intrusions cut across a formation of sedimentary rock, it can be determined the intrusion is younger than the rock. In geology, when igneous intrudes sedimentary rock, it shows the igneous is younger than the sedimentary rock. It is said that an igneous intrusion is younger than a sedimentary rock when the igneous intrusion cut across the formation of sedimentary rock. In geology, when an igneous intrusion cuts across sedimentary rock, it can be known that the igneous is younger than the sedimentary rock.
