What's Happening?
Researchers from Cambridge's Department of Earth Sciences have developed a new atlas mapping the global distribution of critical-metal-bearing igneous rocks, which are primary sources of rare earth elements. The study, published in Nature Geoscience,
reveals that these rocks often form near the thick and ancient cores of major continents, where variations in the Earth's lithosphere play a crucial role. The findings provide predictive insights into where rare earth deposits might form, potentially guiding future exploration efforts. Rare earth elements are essential for various technologies, including smartphones and clean energy solutions.
Why It's Important?
The atlas offers a significant advancement in the search for rare earth deposits, which are critical for the production of modern technologies. As global demand for these elements increases, particularly for clean energy and high-tech applications, the ability to predict and locate new deposits becomes increasingly valuable. This research could reduce dependency on imports, particularly from China, and enhance the security and sustainability of supply chains. The findings may also stimulate further scientific and commercial interest in exploring and developing new rare earth resources, impacting industries and economies worldwide.
What's Next?
The research team plans to extend their study to include older rock formations, which host most of the economic rare earth deposits globally. This could provide further insights into the geological processes that lead to the formation of these valuable resources. As the atlas is utilized by exploration companies and governments, it may lead to new discoveries and the development of rare earth mining projects. The ongoing research and its applications could play a crucial role in shaping the future of the rare earth industry and its contribution to technological advancements.
