摘要
为评价研究矿点成矿潜力,野外采用DWJ-3B型微机激电仪开展中间梯度法扫面测量,圈定出一长1600m、主体宽约200m的高极化异常带。为进一步评价异常带深部潜力,采用GDP-32Ⅱ多功能电测系统开展时间域单极-偶极激电测深工作,测量结果显示深部亦存在高极化异常。平面、深部极化异常与矿区已知矿化露头相对应,推测激发极化异常为矿体引起。综合地质-地球物理研究认为,矿区具有较好成矿前景,激发极化法对矿区进一步找矿评价工作有着积极的指导意义。
In order to estimate mineralization potential of target mineral occurrence,DWJ-3B induced polarization central gradient array method combined with GDP-32Ⅱ Geophysical Data Processor time-domain induced polarization pole-dipole array method is used.One polarization anomaly,corresponds a mineralized outcrop,had been discovered.The anomaly of possible orebody has 200 meters wide,1600 meters long with continuous extension,and depth portion extension.It is indicated that application of induced polarization method is efficient to realize distributed characters of orebodies in the investigation area,and also can provide preliminary basis for next step prospecting work.The investigation area has good metallogenetic prospect.
