The Application Of Comprehensive Geophysical Prospecting To The Huo Geqi Orefield In Geology And Mineral Resources

Comprehensive geophysical prospect for predicting deep concealed rock and the ore-body is a fast and effective way.The Huogeqi ore field is located in northwest of the North China platform in Inner Mongolia,which is a SEDEX type deposits which mainly output copper,iron,lead,zinc.There have favorable tectonic environment and metallogenic geological setting.Therefore,using Comprehensive geophysical prospecting methods with geological data prospects and analyzes the ore field in deep and surrounding and carries out the anomaly verification.In the last we discuss the effectiveness of geophysical methods,and whether these methods are suit other abnormal regions.In the paper,we introduce in detail the new achievement which 1:10000 high-precision magnetic surveys obtain in this area.The high-precision magnetic data processed with method of reduction to the pole and upward continuation and derivation offer plentiful information on magnetic anomalyIn this area,delineating 6 magnetic anomalous areas,we carry out qualitative and quantitative interpretation,then select 2 anomalous areas to carry out two-dimension reversion,and choice 3 profiles to carry out TDIP survey,and carry out MT and CSAMT survey in low electrical resistivity and high polarization resistance section to narrow the target region.Afterwards combing strata,magmatic rock,tectonic,the interpretation results prove to be good by drilling vivification.Therefore through the successful application of comprehensive geophysical prospecting method,lay a foundation to conduct comprehensive geophysical prospecting in future.
