摘要
山东省地矿局第五地质大队聚焦国家战略性关键矿产,针对山东郗山稀土矿开展勘查研究。通过技术创新,构建“重磁联合圈定岩体+放射性定位矿体露头+深部钻探验证+AI分析”技术体系,建立鲁西“碳酸岩-碱性岩型”稀土成矿模型,实现找矿效率提升40%。探获规模化稀土矿产地,伴生稀有金属具高价值,提前超额完成国家“十四五”找矿目标,为全国稀土资源保障体系建设贡献山东力量。
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.
