摘要
Using 1∶50 000 high precision aeromagnetic data in combination with metallogenic geological background and structural characteristics,the authors analyzed aeromagnetic anomaly features,divided metallogenic belts of Qimantag area according to the distribution of known ore deposits (ore spots),screened out a group of key ore-prospecting anomalies,established the composite ore-prospecting criteria based mainly on aeromagnetic anomaly information,and on such a basis,delineated quite a few polymetallic prospective segments.
