Abstract: Maoniugou CuAu deposit is located in Elashan metallogenic belt,which is belongs to skarn type CuAu deposit.The founded three CuAu orebodies are mainly situated in or out of the contact zone of the skarn and occurred in middle stratum of Middle Triassic Gulangdi Formation.The orehosted rock is is skarn and marble.The wall rock alteration includes silication,skarnization,chalcopyrite,pyritization,magnetic pyritization,etc.The interpretation and analysis results of the soil geochemical survey and induced polarization intermediate gradient survey show that:AP3 anomaly (element combination are AuASSbHg,CuPbZnAg and WBiMo ) and DHJ2 low resistance and high polarization anomaly are the the important physicchemical prospecting indicators of the mining area,which are in good nested and zonal distributed along the skarn belt;the nested area of AP3 comprehensive anomaly and DHJ2 polarization anomaly, DHJ3 high polarization center,AP3 comprehensive abnormal high value area and the AP4 and AP5 comprehensive anomaly areas distributed at the both sides of skarn can be taken as the mineralization enrichment areas in the mining area.It is suggested that some related engineering verification work can be conducted in this mineralization enrichment areas,and the prospecting breakthrough will be realized.
