New research proposes that Earth’s early continents could have formed through high-pressure melting of the crust rather than subduction, potentially delaying the start of plate tectonics and revising our understanding of Earth’s geological history and its impact on life.
The formation of Earth’s continents billions of years ago created a foundation for life to flourish. However, scientists remain divided on how these landmasses came into existence and whether the geological processes involved are the same as those we observe today.adds new information to that debate, poking holes in the leading theory of continent formation. Hernández Uribe used computer models to study the formation of magmas thought to hold clues to the origin of continents.
“Using my calculations and models, you can get the same signatures for zircons and even provide a better match through the partial melting of the bottom of the crust,” Hernández Uribe said. “So based on these results, we still do not have enough evidence to say which process formed the continents.”The results also raise uncertainty about when plate tectonics started on Earth. If Earth’s first continents formed by subduction, that meant that continents started moving between 3.
