New research from HKU geologists suggests that Earth’s first continents were born not from plate tectonics, but from deep mantle plumes rising from within the planet. Researchers at The University of Hong Kong (HKU) have uncovered new insights into how Earth’s first continents came into existence over 2.5 billion years ago during the Archean era. […]



Summary

HKU geologists propose that Earth’s initial continents formed not through plate tectonics, but via deep mantle plumes. These plumes, originating from Earth’s interior, rose and solidified, creating the first continental crust during the Archean era, over 2.5 billion years ago. This contradicts the traditional plate tectonics model for continental formation. The research offers a new perspective on early Earth processes and the origins of its landmasses.
