Extinct volcanoes are hard to study – we never see them erupt. Using a unique experimental technique, we were able to recreate a certain type of extinct volcano in a lab, learning more about the magma these volcanoes produce.

We found that some rare magma types are surprisingly efficient at concentrating rare earth elements. This is a group of metals with crucial applications in several high-tech industries, such as magnets for electric vehicles and wind…
