摘　　要：本文对万山汞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 ,含量明显升高 ,而 F与 Cl主要富集于蚀变岩石中。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。We have systematically studied the geochemical characteristics of halogens in the Wanshan Hg Deposit. Br and I are highly enriched in the wall rocks, alteration rocks and ores, and increase from wall rocks through alteration rocks to ores. F and Cl are enriched mainly in the alteration rocks. F, Cl, Br and I are enriched in the upper wall rocks of buried orebodies, showing that the halogens can be used as indicator elements of buried ores such as the Wanshan Hg deposit.
