Some of these minerals are the oldest Earth materials ever discovered, and therefore yield clues about what the planet was like after it formed 4.5 billion years ago. In this new Science Bulletins video, travel to a remote island off Greenland's coast and a zircon-making lab in New York State to learn how geologists are using these time capsules to build new hypotheses about the early Earth.
