No.5 Geological Brigade of Shandong Provincial Bureau of Geology and Mineral Resources has focused on national strategic key minerals and conducted exploration and research on Xishan rare earth deposit in Shandong province. Through technological innovation, a technical system that combines "gravity and magnetic delineation of rock bodies+radioactive positioning of orebody outcrops+deep drilling verification+AI analysis" has been constructed, and a "carbonatite-alkaline rock type" rare earth mineralization model in western Shandong province has been established. Prospecting efficiency has increased 40%. Large scale rare earth deposits with high value associated rare metals has been discovered, and national "14th Five-Year Plan" has been completed in advance. It will provide support for the construction of national rare earth resource security system.
