Unconformities - An erosional surface unconformity is always younger than the strata upon which it is developed and the features that it truncates, but it is older than overlying strata or features which cut across it Rule 4.

Cross-cutting Relationships - A fault or intrusion that offsets or cuts across another fault or intrusion is always the younger because the original fault or intrusion had to exist before it could be offset by a fault or cut by an intrusion Rule 5. Folding Precedes Faulting - In general, when placed under stress, rocks fold as much as possible before they rupture and fault.
