稀有金属新矿床类型的发现和成矿机理的研究对建立国家资源安全体系具有重要意义。前期研究结果表明，山西一些煤中高度富集有益金属元素镓、稀土元素、铀、硒、锂和铼，为产生具有中国煤炭资源特性的前沿创新性成果提供了重要机会。项目将以山西省富集有益金属元素的煤为研究对象，充分发挥煤地质学、矿床学、岩石学和矿物学等学科交叉的优势，以揭示山西省煤中有益金属元素时空富集特征为出发点，以查明有益金属赋存状态为技术关键，以金属元素来源、迁移和富集为主线，拟解决两个关键科学问题：煤中金属元素微观赋存状态和宏观时空分布的主控地质因素，煤中金属元素的富集或成矿机理。该关键科学问题的解决，将为山西省煤型稀有金属矿床的研发利用奠定理论基础，对其他地区新型稀有金属矿床的发现具有重要的借鉴意义，有助于阐明成煤母质、煤化作用、煤中矿物形成机制等基本理论问题，也能为区域地质历史演化（如沉积源区隆升和沉降）提供重要的煤地质学证据。

The findings of coal-hosted ores and study on their mineralization mechanism are essential to the resource security of the country. Previous studies have indicated that some coals in Shanxi Province are significantly enriched in critical metals including Ga, rare earth elements, U, Se, Li and Re, which can enable leading and original studies on coal resources and characteristics of China. The object of study of this project will be critical metals in coals of Shanxi Province. This project will aim to investigate the origin, migration and enrichment characteristics of critical metals in the studied coals. By using the knowledge of coal geology, ore deposit geology, petrology and mineralogy, two key scientific problems are expected to be solved, namely the modes of occurrence of critical metals microscopically and the geological controlling factors for their spatial and temporal distribution macroscopically in the coals. The answers to these two key scientific problems will be the foundation of the research and development of coal-hosted ore deposits in Shanxi Province, which will also provide important information for coal-hosted ore deposits in other places. It will also be essential to elucidate fundamental problems such as original material for coal deposits, coalification processes and mineral formation processes. Moreover, it can provide geological evidences for regional geological history (such as the uplift and depression of source region) from coal geological point of view.
