摘　　要：本文对贵州万山汞矿、独山半坡锑矿卤素元素地球化学特征进行了较系统的研究。研究表明，Br与Ⅰ在矿区赋矿围岩、蚀变岩及矿石中都有不同程度的富集，从赋矿围岩→蚀变岩→矿石，其含量明显升高，而F、CI主要富集于蚀变岩中。在隐伏矿体上部围岩中，F、Cl、Br、I都有异常显示，这种卤素元素异常对寻找隐伏矿体具有指示意义。The authors' studies of geochemistry of halogen elements in the Wanshan mercury deposits and Banpo antimony deposits show that their geochemical pattern from nonmineralized rocks through altered horts to orebodies is a remarkable increase in Br and I; the F and Cl elements,instead, tend to be concentrated in altered hosts. In addition, there are anomalies of F, CI, Br and I in the host rocks above the conceded orebodies. Obviously, this anomalous pattern of halogen elements of F, CI, Br, and I can be used as a geochemical tool to search for hidden orebodies in these areas.
