Principle of Original Lateral Continuity

strata (layers) extend laterally until theythin to nothing (pinch out) at the edgeof the depositional basin

Principle of Inclusions

any piece of a rock that has becomeincluded in another rock must be olderthan the host rock

Principle of Baked Contactsigneous rocks “bakes” the surrounding rocksand must be younger than the rocks it bakes
