Ride the cosmic clock hidden in zircon crystals to reveal how the North American continental plate was built.
Using isotopic fingerprints—U/Pb and Pb isotopic ratios decoding billions of years of crustal recycling, subduction zones, and volcanic arc collisions that forged the continental crust beneath our feet.
Tectonic assembly from ancient terranes to modern cratons, showing how tiny zircons preserve Earth’s violent geologic history.
