Abstract:In order to find concealed iron deposits in western Beishan of Gansu Province, the authors studied in detail 1:50 000 aeromagnetic data of the Gubaoquan iron ore district, performed 1:5 000 surface magnetic survey at the key area based on anomalies delineated by aeromagnetic survey, divided the anomalous area into two anomaly zones, delineated C1-C8 geomagnetic anomalies, and then made deduction, interpretation and engineering verification for these eight anomalies, which led to the discovery of the Gubaoquan iron deposit. Based on an analysis of the corresponding relationships between aeromagnetic anomalies, geomagnetic anomalies and ore bodies, the authors hold that there are still some aeromagnetic anomalies in the outskirt of the ore district which deserve further work.
