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.

The U.S. Geological Survey says the Appalachian region contains an estimated 2.3 million metric tons of undiscovered, economically recoverable lithium—an amount it calculates could replace about 328 years of U.S. lithium imports at 2024 levels.

China's Ministry of Natural Resources has published an atlas from two decades of marine geological surveys, mapping the location, concentration, and distribution of dozens of elements in seabed sediments, including rare earths, iron, manganese, and copper. State broadcaster CCTV reported the atlas as a 'master navigation map' for marine development and conservation, based on over 20,000 observation points. Researcher Dou Yanguang from the Qingdao Institute of Marine Geology said it enables precise targeting of resources and identification of sensitive ecological zones.

Japan has identified an enormous underwater rare earth deposit 6,000 meters deep near Minamitorishima, the remote Pacific atoll central to its accelerated deep-sea mining plans. Detailed in a recent WIRED report, the find—building on equipment installation earlier this year—bolsters Tokyo's drive for independence from Chinese supplies of these critical manufacturing materials.

Brazil's Chamber of Deputies approved a bill on Wednesday that sets rules for the exploration of critical minerals and rare earths. The text includes R$ 5 billion in incentives and a council with veto power over foreign partnerships. The vote came on the eve of a meeting between Presidents Lula and Donald Trump.

Nuclear physicists at the University of Tennessee have made three key findings about the rapid neutron-capture process that forms heavy elements like gold in stellar events. Their research, conducted at CERN's ISOLDE facility, clarifies how unstable atomic nuclei decay. The results, published in Physical Review Letters, could refine models of element formation in the universe.
