Zircon: How this tiny, ancient mineral is upending what scientists believed about early Earth
About this episode
How did the early Earth, over four billion years ago, evolve into the planet we know and love today? It’s a big question, and an open question. To get answers, geologists turn to a surprising source — a tiny mineral no bigger than the diameter of a human hair, that has secrets about our planet locked away in its crystal structure. This miniscule mineral, with its big stories is called zircon.
