摘　　要：丁家林金矿床V1脉带和太阳坪金矿床V9、V4矿脉的地球物理、地球化学和地质剖面研究表明,磁化率异常基本与化探原生晕Au异常同步(具相同的指示意义),Au出现正异常时,磁化率出现负异常,并与地质剖面的矿化部位对应很好;矿区的磁线理、磁面理等磁组构研究表明,磁组构能与岩组研究一样,解决岩石变形的应力场问题。磁性研究是金矿找矿、地质工作的有效方法与手段。The study of the geophysical,geochemical and geological section of the V1 vein belt of Dingjialing gold deposit and V9,V4vein belts of Taiyangping gold deposit shows that it is synchronous between the magnetic susceptibility abnormal and primary halo Au abnormal of geochemical prospecting, which has the same indicated significance. When Au is at positive abnormal, the magnetic susceptibility is at negative abnormal and corresponds well with the mineralization position of geological section. The magnetic lineation and magnetic foliation study of the ore area show that the magnetic fabric study can proclaim the stress field of rock deformation as the petrofabric analysis. The magnetic study is an effective method at the gold prospecting and geological work.
