Extinct Volcanoes May Hold Key to Rare Earth Element Supply

New research suggests iron-rich magma in extinct volcanoes could be a significant source of rare earth elements crucial for modern technology.

A study published in Geochemical Perspectives Letters reveals that iron-rich magma in extinct volcanoes is highly efficient at concentrating rare earth elements.
Researchers simulated volcanic eruptions in laboratory conditions, discovering that this type of magma can be up to 200 times more efficient than magma from active volcanoes.
Rare earth elements are essential for renewable energy technologies, electric vehicles, and various modern devices, with demand expected to quintuple by 2030.
China currently dominates the rare earth supply chain, but new findings could enable other countries to become major players and reduce global dependency.
Potential sites for exploration include extinct volcanoes in the United States, Chile, and Australia, which are already mined for iron-ore, offering a dual benefit for mining companies.
