Faults and Unconformity?

Question

I'm trying to do my science homework and I need help on labeling layers intrusions etc from youngest to oldest. In the picture the fault starts essentially right on line with the unconformity. Would the fault be older than the unconformity?

Answer 1

The unconformity represents an erosional surface. If the fault comes to the surface at the unconformity it is likely that the fault happened before the unconformity.
