Are These Earth's Oldest Rocks?

Get ready to dig deep into the geological weeds with Dr. Jesse Reimink and Chris Bolhuis as they tackle the rock-solid debate about Earth's oldest rocks! Is the Ujaraaluk unit in Northern Quebec truly 4.25 billion years old? Or is it just a rocky mix-up? We meticulously break down isotope geochemistry, hydrothermal beauties, and field observations. Discover how extinct isotope systems shed light on our planet's fiendishly old secrets. Plus, we'll uncover the realities of cross-cutting relationships and metamorphic mysteries. Dive in, and don't get too basalt by the complexity!
