摘要
5 antimony abnormal zones in Sandu antimony deposit are determined by transient electromagnetic 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 prospecting is obvious in the exploration in this area.
