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 Ta
2O
5 resource is 40 000 t, with potential Nb
2O
5 resource of 49 000 t, potential Li
2O 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.
