| 摘 要： | 幕阜山岩体的内、外接触带伟晶岩密集分布,具有较好的稀有金属矿成矿地质条件和找矿潜力。为了进一步研究幕阜山地区稀有金属矿的赋存特征、成矿规律及矿产资源找矿潜力,指导下一步勘查工作,系统梳理了幕阜山地区稀有金属矿勘查工作进展,将湖南境内的幕阜山地区划分为5个成矿远景区,评价了各成矿远景区的找矿潜力,进一步探讨了该地区的找矿方向。幕阜山地区的锂铌钽铍矿资源主要集中在幕阜山岩体西南缘的仁里—传梓源与上大洲—南江桥成矿远景区; 预测Ta2O5潜在资源量约40 000 t,Nb2O5潜在资源量约49 000 t,Li2O潜在资源量约320 000 t,BeO潜在资源量约48 000 t。可对幕阜山地区稀有金属找矿勘查和研究起到指导作用。

| Abstract: | Pegmatites are densely distributed in the inner and outer contact zone of Mufushan batholith, with good metallogenic geological conditions and prospecting potential of rare metal deposits. In order to further study the occurrence characteristics, metallogenic regularity and prospecting potential of rare metals in Mufushan area and further guide the exploration work, the authors in this paper systematically summarizes the rare metal ore exploration achievements in Mufushan area. We divided Mufushan area in Hunan Province into five metallogenic prospective areas and evaluated their prospecting potential. Besides, the prospecting direction in this area is further discussed. Lithium, niobium, tantalum and beryllium ore resources in Mufushan area are mainly concentrated in the metallogenic prospect areas of Renli-Chuanziyuan and Shangdazhou-Nanjiangqiao on the southwestern edge of the Mufushan batholith. The predicted potential Ta2O5 resource is 40 000 t, with potential Nb2O5 resource of 49 000 t, potential Li2O resource of 320 000 t, and potential BeO resource of 48 000 t. This work can provide references for exploration and research of rare metal deposits. |
