Zircon crystals

  • Exhibition Text

    • This quartz pebble conglomerate formed three billion years ago, but the zircon crystals in it are up to 4.276 billion years old, making them the oldest dated material on Earth. Zircons undergo uplift, erosion, and growth. Their cores are often older than the rocks in which they are found.
