Application of Comprehensive Geophysical Prospecting Method in the Survey of Copper Polymetallic Deposit in Bainaimiao Inner Mongolia

摘要

Comprehensive geophysical prospecting method is the most commonly used exploration method in searching for deep concealed copper polymetallic deposit. This paper put compound comprehensive geophysical prospecting of electric-medium gradient method and the controlled source audio frequency magneto-electrotelluric exploration into practice in the metallogenic prospect area determined by the BAINAIMIAO Inner Mongolia regional geology and geophysical characteristics. Finding out the specific distribution of the anomalous body in the underground space by electric-medium gradient scanning way to delineate ore body and mineralization anomalies, then, by the controlled source audio frequency magneto-electrotelluric exploration for abnormal profile measurement provides the basis for the verification of the drill hole location. The practice shows that, the comprehensive prospecting model is effective, economic and efficient and has certain guiding significance for the exploration of concealed copper polymetallic deposit in the similar geological areas.
