Rare Earth Metal deposited by volcanic activity millions of years ago

Norway and Sweden discover large deposits of important rare Earth metals

Significant deposits of rare earth metals have been found in both Norway and Sweden.


Rare Earths Norway (REN) has announced the discovery of the largest deposit of rare earth elements in Europe at the Fen Carbonatite Complex in southeastern Norway.

The deposit reportedly contains 8.8 million metric tons of total rare earth oxides (TREOs), including an estimated 1.5 million metric tons of magnet-related rare earths, which are vital for technologies like electric vehicles and wind turbines.

This discovery marks a significant advancement in Europe’s efforts to decrease its reliance on imported rare earths, especially from China.


The discovery in Arctic Sweden of over one million tonnes of rare earth metals could significantly aid the EU in reducing its reliance on China for these crucial elements, which are essential for a wide range of high-tech applications.

These findings are critical for the green transition and Europe’s goal of increased self-sufficiency in vital raw materials. It is crucial to acknowledge, however, that the extraction process is intricate and necessitates meticulous attention to environmental impacts.

Due to the required permitting processes and environmental assessments, it could take over a decade for the materials from these discoveries to enter the market.

Fen Carbonatite Complex

The Fen Complex, located in Nome, Telemark, Norway, is renowned for its unique assortment of igneous rocks, such as carbonatite. It represents the remnants of a volcanic feeder pipe from a volcano that erupted 580 million years ago, characterised by carbonate-rich magma. The volcanic pipe’s circular formation spans roughly 2 km in diameter.
