综合物探方法在内蒙古巴彦乌拉铜多金属矿中的应用

采用多种物探方法对深部及隐伏矿体进行定位预测,可以减少或避免异常解释的多解性,提高解释的可靠性和勘查效果。文章以内蒙巴彦乌拉铜多金属矿勘探为例,结合地质、物性等资料,通过对研究区开展高精度重磁测量,初步推断了该区岩性的分布状况;通过CSAMT测量,进一步了解到岩性在空间上的展布情况;对重磁和CSAMT圈定出的找矿有利地段进行了钻孔验证,多孔见到工业矿体;由上述研究可知在该区使用重力、磁法和CSAMT测量进行综合找矿是可行的。

Application of comprehensive geophysical method for exploration on Bayanwulacopper polymetallic depositin Inner Mongolia

Using various of geophysical methods will reduce or avoidthe multiplicity of anomaly interpretation as predicting the location of deep and concealed orebodies,which can improve the reliability of interpretation and exploration effect.This paper preliminarily inferred the distribution of lithology in this area by the high-precision gravity and magnetic measurementstakingBayanwulancopper-polymetallic deposit in Inner Mongolia as an example. It could be furtherly understood thespatialdistribution of lithology by the CSAMT surveyIt was found mineralizing in many drilling holes which drilled in the prospecting area delineated by gravity-magnetic and CSAMT survey.. From the above studies, it showed that comprehensive exploration is feasible by using gravity, magnetic methods and CSAMT measurements.
