Atlas reveals rocks with rare earth element potential, helping pinpoint new deposits

Phys · · 813 words · By University

Researchers from the University of Cambridge have developed a global atlas mapping CO2-rich igneous rocks to help predict the location of rare earth element deposits. The study, published in Nature Geoscience, suggests that the thickness of the Earth's lithosphere plays a critical role in the formation of these mineral-rich rocks.

“A new atlas charts the global distribution of unusual, critical-metal-bearing igneous rocks, finding that they often form near the thick and ancient cores of the world's major continents.”
SINGLE SOURCE
The provided web search results for this claim only provide general definitions of igneous rocks and do not mention the specific atlas or the finding regarding critical-metal-bearing rocks and continental cores. However, Claim 6's evidence mentions a 'New global map' and 'carbonatites' (which are critical-metal-bearing) occurring at margins of thick lithosphere, suggesting the claim is likely true but not independently corroborated by multiple sources in the provided evidence.
