3D Structure Modeling of Typical Ore Bodies in Awulale, Xinjiang, and Ore Prospecting Potential
摘要
Focusing on the overall requirements of increasing reserves and production of iron ore in the Awulale area, Xinjiang, this study relies on newly acquired high-resolution airborne magnetic data from the Chagangnuoer region. Using 3D physical property inversion methods, forward and inverse modeling of aeromagnetic data in Chagangnuoer was conducted, combined with comprehensive analysis of geological data, regional metallogenic patterns, field-measured physical property data, and key anomaly survey results. The results show that Anomalies No. 36, 37, and 48 in the study area exhibit significant ore-induced anomaly characteristics of iron ore. A 3D geological structural model of typical rock-ore bodies in the Chagangnuoer region was constructed based on 3D forward-inverse modeling and 2D sectional interpretations. Resource estimation for the magnetic ore bodies was conducted using the volume method and analogy method, revealing a total iron ore reserve of 11.653 million tons across the three anomalies. Comprehensively considering the metallogenic geological conditions and aeromagnetic anomaly characteristics in the Awulale area, it is concluded that the Chagangnuoer region holds favorable prospecting potential for iron polymetallic deposits. High-resolution aeromagnetic anomalies can provide critical clues for iron ore prospecting prediction and rapid target localization.
