Clare Warren on Divining the History of a Rock
Most rocks were formed many millions of years ago. Since then, some have been largely left alone, while others have been baked at high temperatures and buried at great depths. Clare Warren explains how we can now uncover remarkably precise histories of such rocks, even if they have been through more than one episode of such extreme treatment.
