摘　　要：通过对攀枝花白马钒钛磁铁矿区的区域航空磁测成果以及地面高精度磁测成果进行综合研究,对已探明成矿区域进行验证分析,总结航磁异常特征、地面磁测异常特征与矿产信息的匹配关系,并对未探明地区进行找矿远景评价,从而归纳出白马矿区与控矿因素有关的磁异常特征规律。结果表明,该区域钒钛磁铁矿磁异常强度高,区域磁异常特征明显,磁法勘探在该矿区的岩体划分、构造单元及构造位置的划分、直接找矿等方面有着明显的作用,为解决该区域深部找矿疑难问题、建立地球物理找矿模型提供了磁异常特征的参考。The results of regional aeromagnetic survey and ground high-precision magnetic prospecting of Baima vanadi- um-titanium magnetite mining area in Panzhihua are investigated comprehensively. In addition, the explored mineralization re- gion is verified and analyzed and the matching relationships between mineral information and anomaly characteristics of aero- magnetic and ground magnetic survey are summarized. Besides that, the prospecting evaluation on the unexplored areas is done and the regular pattern of magnetic anomaly that is related to the ore-controlling factors in Baima mining area is drawn. The re- search results show that there is a higher level of vanadium-titanium magnetic anomaly in Baima mining area, and obvious re- gional magnetic anomaly. Magnetic prospecting method has played a great role in classification of rock mass,tectonic unit, tec- tonic position and direct prospecting. The research also provides some reference of magnetic anomaly characteristics for resol- ving the deep prospecting problems and building up a geophysical ore-prospecting model.
