Forskare skapar global karta över fyndigheter av sällsynta jordartsmetaller

Forskare har utvecklat en världskarta som visar var sällsynta jordartsmetaller sannolikt kan finnas. Arbetet kopplar dessa värdefulla metaller till specifika geologiska särdrag djupt under jordens yta.

Ett internationellt team lett av University of Cambridge har tagit fram en prediktiv karta över fyndigheter av sällsynta jordartsmetaller. Studien kombinerar data från cirka 9 000 stenprover med seismiska bilder av planetens inre. Den visar att de relevanta magmatiska bergarterna främst bildas längs de branta kanterna av jordens tjockaste och äldsta kontinentala litosfär.
