- 15. Multiple ChoiceIn this rock layer diagram there are two unconformities, a fault at E and an intrusion at D. Which unconformity occurred first? How do you know?Intrusion D occurred first because the instrusion has been moved by the fault.The fault occurred first because it has moved the intrusion D.Intrusion D occurred first because it can be seen in all of the rock layers.Fault E occurred first because it is a normal fault.
