The Earth may still be LEAKING from the inside for billions of years
Researchers at the University of Science and Technology of China ran machine learning simulations of hydrogen deep inside the planet.
They found signs that the core and mantle have been exchanging material throughout Earth’s history.
Volcanic rocks from Iceland and Baffin Island in Canada hold a clue.
Some have unusually low ratios of deuterium, a heavier form of hydrogen, to ordinary hydrogen, which may point to hydrogen from Earth’s early history.
The researchers suggest hydrogen escaping from the core could explain that. Helium and tungsten isotopes in volcanic rocks could point the same way, toward material rising from the core.
That challenges the idea that the deep mantle’s chemical signatures are just leftovers from Earth’s earliest days.
The oldest parts of the planet may still be on the move…
