Unveiling the Surprising Origins of Earth's First Continents
A new study from the University of British Columbia suggests that the first continents formed through the magmatism of Earth’s current crust’s precursor, known as TTGs, ruling out the need for meteorites or subduction zones. The research indicates that TTG rocks formed from a slow burial, thickening, and melting of precursor crust, disproving the idea that they could’ve formed from subduction zones. This discovery sheds light on the mysterious origin of Earth’s continents during the Archean Eon, challenging previous theories and providing new insights into the formation of the planet's early land masses.
