摘要
采用瞬变电磁法及大功率激电测量在三都高洞锑矿区圈定出5个锑异常带,结合该区成矿地质条件及锑矿床类型,将5个锑异常带划定为找矿靶区,通过钻探及坑道验证,在Ⅰ、Ⅱ、Ⅲ三个锑异常带内共揭露出三个锑矿体。表明利用地球物理勘探方法在该区找矿效果十分明显。
5 antimony abnormal zones in Sandu antimony deposit are determined by transient electromag- netic method and high -precision magnetic measurement, combine with the mineral condition and antimony deposit type in this area, these 5 zones are ensured to be target area. By driUing and tunnel test, 3 antimony orebody in abnormal zones ： I ,Ⅱ and m are found out, it＇ s improved the application of geophysical prospec- ting is obvious in the exploration in this area.
