摘要
半坡锑矿矿石及近矿围岩中Ｂｒ与Ｉ含量很高，分别是地壳丰度值的数十倍至数百倍，这在热液矿床中是十分罕见的，从远矿围岩→近矿围岩→矿石，Ｃｌ、Ｂｒ、Ｉ含量有规律地增高，而Ｆ主要富集在近矿蚀变围岩中，Ｆ、Ｃｌ、Ｂｒ。
It is unique for hydrothermal deposits that Br and I contents of ores and altered rocks from the Banpo antimony deposit are very high,correspondent to n×10 to n×100 times of clark value.Cl,Br.and I contents intend to increase from wall rocks to altered rocks and finally to ores.F is mainly enriched in altered rocks.The enrichment of F,Cl,Br and I indicates that they are likely to be the indicator elements of hunting buried antimony deposits.
