摘　　要：华南是我国战略性矿产钨锡的主产地,且与花岗岩有关的钨锡矿床附近常发育Li、Rb、Be、Nb、Ta等稀有金属矿床,但对这两类矿床的成因联系并不清楚。通过收集整理华南与花岗岩有关的稀有金属矿床和钨锡矿床的研究资料,对稀有金属矿和钨锡矿的成因关系进行初步分析,认识到这两类矿床具有区域-矿田-矿床-矿物多尺度的空间相关性,成矿时代、成矿物质来源及成矿作用相近性,且成矿主要与燕山期高分异花岗岩有关。两者之间“偶极”式分布样式为利用华南极为丰富的钨锡矿床勘探及研究成果寻找稀有金属矿床提供了依据。The strategic mineral W-Sn deposits in China are mainly concentrated in South China, and many rare metal mineralizations, such as Li, Rb, Be, Nb, Ta, etc., are often coproduced with them. However, the genetic relationship between them is unclear. Based on the analysis of research data related to granite-related rare metals and W-Sn deposits in South China, we believe that the two types of mineralization have a close spatio-temporal relationship at multiple scales, such as metallogenic belts, ore fields, deposits, and minerals. In addition, the ore-forming material source, mineralization process, and ore-controlling structures are similar, indicating that they may have derived from a same granitic mass and the mineralization usually have close genetic relationship with the high evolved granite. Therefore, the exploration and research data of W-Sn deposits in South China can be used to explore and study rare metal deposits.
