大功率激电在承德槽子沟金矿勘查中的应用

Application of high power IP method to the exploration of Caozigou gold deposit,Chengde City

应用大功率激电法对深部隐伏矿体的探测是一种行之有效的方法。通过激电中梯对承德槽子沟金矿区进行激电面积性测量,圈定出与金矿伴生的金属硫化物及氧化物引起的激电异常分布区带,利用激电测深查明地下极化异常体的展布,而后结合已知地质、物性资料布置验证钻孔,并取得了较好的勘查效果。本文总结出利用大功率激电方法勘查隐伏金矿的行之有效工作模式,该找矿模式可广泛应用于同类隐伏金矿的勘探之中,必将有力提高物探方法寻找隐伏金矿的勘探水平。

It is effective to detect deep-seated concealed ore-bodies using the high power IP （induced polarization） method. IP intermediate gradient method was applied in area measuring in Caozigou gold de- posit, Chengde City, and distribution zone of IP anomalies caused by metallic sulfides and oxides that asso- ciated with gold were outlined. Using IP sounding to find out the distribution of underground polarization anomalies, and then combining them with known geological and petrophysical data to arrange confirmation drillings have achieved good results in this area. This paper summarized an effective working model using high power IP method to prospect concealed gold deposits, and the prospecting model can be widely ap- plied in exploration of the similar concealed gold deposit ,effectively improving exploration level in search- ing for concealed gold deposit by using geophysical methods.
