激发极化法在内蒙古大砬沟银多金属矿勘查中的应用
|
摘要
激发极化法是探测多金属硫化物矿床的有效方法之一,被广泛应用于矿产勘查中。在内蒙古大砬沟银多金属矿勘查中,利用时间域激电中梯扫面测量,圈定了2处激电异常,在激电异常有利部位开展激电测深工作对极化体的埋深和空间赋存状态有了进一步了解,有效指导了探矿工程施工。经槽探和钻探验证,激电异常是由银矿(化)体和铜矿(化)体引起,达到了找矿目的。
The induced polarization(IP)method is one of the effective methods to detect polymetallic sulfide deposits,and is widely used in mineral exploration. Through time domain IP intermediate gradient scanning measurement,2IP anomalies have been circled in the exploration of silver polymetallic deposit in Dalagou area of Inner Mongolia. The IP sounding work in the favorable position of IP anomaly has further understanding of the buried depth and space occurrence state of the polarization body,which has effectively guided the exploration engineering construction. By trenching and drilling verification,IP anomalies are caused by silver and copper mineralization bodies,and the purpose of prospecting is achieved.
