摘　　要：地质大数据推动地球科学研究逐渐从定性研究向半定量研究、定量研究迈进。稀散金属(锗、镓、铟、铊、铼、镉、硒、碲)是我国的优势矿产资源,因传统用途局限,研究相对不足。本文通过对759处稀散金属矿床(点)资料的系统梳理,定量分析了542处稀散金属矿产地(含矿点)的成矿密度、成矿强度及各成矿期稀散金属矿的成矿强度问题。研究结果表明:中国稀散金属矿床空间分布广泛但相对集中,可划分为七大主要资源集中区;广西、云南矿床(点)数量最多(61处),云南资源储量最大(24×10^(4)t),河南是稀散金属矿成矿密度最大、成矿强度最强的省份(3.4处/10^(4)km^(2)、8100 t/10^(4)km^(2))。中国稀散金属矿床时间分布不平衡,燕山期是主要成矿阶段,成矿密度最大达2.3处/Ma,而喜马拉雅期成矿强度最强,稀散金属资源储量超4000 t/Ma。划分了18个稀散金属矿集区,兰坪-普洱(DM-J13)成矿强度最大。今后应加强稀散金属综合研究,加强其地质找矿与开发利用,促进新质生产力的形成与发展。Geological big data has promoted geoscience research from qualitative to semi-quantitative and quantitative.Dispersed metals including germanium(Ge),gallium(Ga),indium(In),thallium(Tl),rhenium(Re),cadmium(Cd),selenium(Se),tellurium(Te),although not widely recognized by the general public,are indeed valuable mineral resources in China.Based on the data of more than 759 dispersed metals deposits(points),the paper quantitatively analyzes the metallogenic density,intensity and ore-forming periods of 542 dispersed metals ore.The research shows that the dispersed metals in China have an obvious trend of spatiotemporal concentration distribution,and it can be divided into seven major resource concentration areas.Guangxi and Yunnan have the largest number of deposits(61).Yunnan has the largest resource reserves(24×10^(4) t),and Henan is the province with the highest metallogenic density and strongest metallogenic intensity(3.4 deposits/10^(4) km^(2),8100 t/10^(4) km^(2)).The time distribution of dispersed metal deposits in China is unbalanced.Yanshanian stage is the main mineralization stage with the highest metallogenic density of 2.3 deposits/Ma,while Himalayan stage has the strongest metallogenic intensity and the reserves of dispersed metal resources exceed 4000 t/Ma.The metallogenic intensity of Lanping-Pu’er(DM-J13)is the strongest among 18 dispersed metals ore concentration areas.In the future,it should strengthen the comprehensive study of dispersed metals,strengthen their geological prospecting,exploitation and utilization,and promote the formation and development of new quality productivity.
