河北省宽城县沙窝店地区地质-地球物理特征及找硫铁矿效果

GEOLOGY—GEOPHYSICAL FEATURE AND PYRITE-PROSPECTING RESULTS AT SHAWODIAN AREA IN KUANCHENG COUNTY OF HEBEI PROVINCE

矿区内铁帽发育,矿化特征明显,含矿层和黄铁矿体在电性上与围岩之间存在着明显的电性差异,采用时间域激发极化法和视电阻率法等综合物探方法深部找矿,共发现有意义异常五处。结合地质、钻探资料认为它们分别是由黄铁矿体、规模较小(连续性较差)的矿化体及碳质页岩引起的异常,说明运用综合物探,结合地质进行深部找矿效果明显。

There are a lot of gossans and obvious mineralization characters in the ore section with the obvious electric differences between ore-bearing bed, the pyrite orebody and the wall rock. We prospect deeply with some compositive physical prospecting methods including time induced polarization method and apparent resistivity method and found five significant anomaly which were caused by pyrite and small scale （worse continuity ） mineralization orebody and carbonaceous shale, all of which show that the compositive physical prospecting method combined with geology is well for deeply prospecting.
