New Rare Earth Deposits Discovered in China
Quick Look
- A new discovery of rare earth deposits in China could alter the established understanding of their distribution, potentially rewriting the 'heavy in the south, light in the north' pattern.
- The findings were published by a team from the Chinese Academy of Sciences.

Why It Matters
Rare earth elements are critical minerals used in various high-tech applications. China is the world's largest producer and processor of these elements, handling nearly 90% of global processing.
The discovery of the new deposits “could potentially rewrite the ‘heavy in the south, light in the north’ pattern of rare earth resources in China”, a team from the Chinese Academy of Sciences’ (CAS) Institute of Geology and Geophysics and the Heilongjiang Bureau of Geology and Mineral Resources said in a paper published in the Chinese journal Acta Petrologica Sinica last month.
Rare earth elements are a group of 17 critical minerals – including cerium, neodymium and dysprosium – that are used to produce electronics, large magnets, superconductors, and green and defence technologies.
As the world’s largest producer and consumer of rare earths, China handles nearly 90 per cent of global processing of the critical minerals.
The CAS-Heilongjiang team said that while rare earths were abundant in China, the places they were found did not always follow the patterns geologists would have predicted from rock types like alkaline granite.
