Scientists Just Found the OLDEST Rocks on Earth — And They’re Right Here in Canada!

In this episode, Shane sits down with Dr. Jonathan O’Neil, Earth sciences professor at the University of Ottawa, to discuss a groundbreaking discovery that could rewrite our understanding of early Earth. O’Neil and his team have confirmed that rocks from Quebec’s Nuvvuagittuq Greenstone Belt are over 4.16 billion years old—making them the oldest preserved rocks ever found on Earth. The conversation dives into how these ancient formations offer rare insights into the Hadean eon, a time when Earth was just beginning to cool, oceans may have formed, and the earliest signs of life and plate tectonics were emerging. This discovery not only resolves a long-standing scientific debate but also opens a new chapter in the story of our planet’s origins.
