The Nuvvuagittuq Greenstone Belt is a fascinating and controversial geological site that challenges our understanding of Earth’s earliest history. It may hold clues to how our planet formed, how its crust evolved, and how life emerged and survived in harsh environments. As more data and analyses become available, we may be able to unravel some of these mysteries and appreciate the significance of these ancient rocks.
