    • 2022 March 18, Joël Brugger, Barbara Etschmann, Marion Louvel, “Powerful X-rays reveal the birth of giant rare earth element deposits – and may give clues for sustainable mining”, in The Conversation‎, archived from the original on 18 March 2022:
      All rocks around us contain significant amounts of rare earth elements, but they become concentrated in these exotic magmas through slow crystallisation in Earth’s crust. This is usually not enough to make an ore deposit, which consists of millions of tonnes of rock made up of between 5 and 50% by weight of rare earth elements. A second step of concentration is required.
      In giant deposits such as Bayan Obo in Inner Mongolia, hot fluids loaded with carbonate appear to have undergone this extra concentration step. But exactly how has been a mystery.
