摘　　要：稀散金属矿在战略性新兴产业发展中具有不可替代的重要作用。湖南省稀散金属矿资源丰富,全省共有稀散金属矿产地39处,查明稀散金属矿资源量62072.62 t。在系统总结湖南省各类稀散金属矿的地球化学、矿物学特征和分布规律的基础上,结合笔者近几年在稀散金属矿调查研究方面取得的成果,对湖南省稀散金属矿的资源潜力进行了初步分析。本次研究将湖南省稀散金属矿划分为岩浆热液型、矽卡岩型、沉积型、浅成中-低温热液型和砂矿型5种矿床成因类型。按主矿种,铅锌(多金属)矿床中伴生的稀散金属矿规模最大。湖南省稀散金属矿成矿作用时间跨度大,从加里东期到喜山期均有产出。其中燕山期镓、铟、锗、铼矿床的数量最多、规模最大。研究认为,湖南省稀散金属矿勘查研究程度较低,成矿条件有利,矿化标志明显,具有良好的资源潜力。Rare and scattered metal ores play an irreplaceable role in the development of strategic emerging industries.Hunan province is rich in rare and scattered metal ore resources,with a total of 39 rare and scattered metal ore producing areas in the province.The identified rare and scattered metal ore resources amount to 62072.62 tons.Based on a systematic summary of the geochemical and mineralogical characteristics and distribution patterns of various rare earth metal deposits in Hunan province,this article combines the author's achievements in the investigation and research of rare earth metal deposits in recent years to conduct a preliminary analysis of the resource potential of rare earth metal deposits in Hunan province.This study divides rare and scattered metal deposits in Hunan province into five types of deposit genesis:magmatic hydrothermal type,skarn type,sedimentary type,shallow to medium low temperature hydrothermal type,and sand deposit type.According to the main ore type,the scale of rare and scattered metal deposits associated with lead-zinc(polymetallic)deposits is the largest.The mineralization process of scattered metal deposits in Hunan province spans a long time,with outputs occurring from the Caledonian period to the Xishan period.Among them,the Yanshanian period has the largest number and scale of gallium,indium,germanium,and rhenium deposits.Research suggests that the exploration and study of rare and scattered metal deposits in Hunan province is relatively low,with favorable mineralization conditions and clear mineralization indicators,indicating good resource potential.
