高精度磁测在四川金河—树河地区1∶5万矿调中的应用

摘要

在四川省盐源县金河—树河地区开展了1∶5万高精度磁测,对磁测数据采用向上延拓、化极、小波断裂分析、2.5D人机交互反演等方法,进而分析不同磁场区的磁性特征,对区内的铁矿体、断裂构造和岩浆岩的磁性特征进行阐述和解释,提出了4个成矿远景区,认为区内依然存在不同类型铁矿资源的找矿潜力.%High precision magnetic survey at scale 1∶ 50 000 is conducted in Jinhe river-Shuhe river area.The data measured are processed with upward continuation,reduction to pole,small wave fissure analysis and 2.5D human-computer interactive inversion and magnetic feature of different magnetic fields analyzed.The magnetic feature of iron ore bodies,faults and intrusions in the area are described and interpreted.Based on the description and interpretation 4 potential areas are pointed out.The area is still potential for different type of iron ores.
