Scientists Uncover Hidden Rare Earth Treasure Map Beneath Ancient Continents

A Cambridge-led global study links rare earth–rich rocks to the thickest, oldest parts of Earth’s lithosphere.

Researchers found CO2-rich igneous rocks cluster above ancient continental roots where magma can remain trapped longer.

That trapped magma may help concentrate rare earth elements into economically valuable deposits.

The findings, published in Nature Geoscience, could improve resource exploration and reduce the risk of failed searches.
