WebCONTACT METAMORPHISM - after the intrusion of H, there is a contact metamorphism occurs around the intruded rock. H is younger than B because B is burned (metamorphosed), therefore B is older the H. B is older than H, but younger than F (based on the Law of Superposition). Again, it is older than H because it is affected by contact … Weba ring of metamorphic rocks adjacent to an igneous intrusion How is quartz sandstone metamorphosed into quartzite during contact metamorphism?
