幕阜山西南缘黄柏山稀有金属伟晶岩密集区的发现及意义

Discovery and significance of Huangbaishan rare metal pegmatite concentration area on southern margin of Mufushan

幕阜山地区是中国重要的稀有金属矿集区。中国地质科学院矿产资源研究所与湖南省核工业地质局三一一大队在总结区域稀有金属成矿规律的基础上,于2019年度在幕阜山西南缘黄柏山地区新发现稀有金属伟晶岩密集区一处。区内伟晶岩呈现出良好的铌钽锂成矿性,易于开采、分选及运输,具有较高的经济价值。区域伟晶岩具较高的岩浆分异演化程度,且呈现出较为清晰的稀有金属矿化分带,具有良好的成矿潜力。

Mufushan is an important rare metal concentration area in China. On the basis of summarizing the regional rare metal metallogenic regularity, the Institute of Mineral Resources of the Chinese Academy of Geological Sciences and the No. 311 Geological Party of Hunan Nuclear Geology discovered a new rare metal pegmatite concentration area in Huangbaishan area on the southern margin of Mufushan in 2019. Pegmatites show obvious Nb,Ta and Li mineralization, and are easy to be mined, sorted and transported, thus having high economic value. Regional pegmatites have experienced high degree of magmatic differentiation and evolution and show clear rare metal mineralization zoning, thus having good ore-prospecting potential.
