The mineral zircon is the oldest known piece of Earth existing on the surface today. The oldest bits date back as far as 4.37 billion years — not too far from the age of Earth itself at about 4. ...

The mineral is zircon, and scientists have found bits of it that formed 4.37 billion years ago, not too long after the proto-Earth's epic collision with a Mars-sized object that spawned our moon.

Geologists rely on tiny crystals of the mineral zircon to understand the timing of key events in Earth's early days, like the rising of continents and the emergence of oceans.

Zircon is the "time-lords" of the earth. They are indestructible and take up radioactive materials, so they're used to track events in deep time that… Meet the mineral known as the time lord | LAist ...
