摘　　要：介绍了双频激电法在西藏地区的应用情况。通过在测区进行双频偶极工作,圈定了4个激电异常,综合测区岩石标本的电、物性特征,对异常进行了推断和解释。从所测量的视幅频率和视电阻率结果分析,双频激电法完全能适应西藏这种气候寒冷、海拔高、地形起伏大的地区,并能取得良好的地质效果。The application of the dual frequency induced polarization method was carried out in Tibet, and the dual frequency dipole induced polarization was used to delineate four I anomalies, detect the characteristics of the sources and the polarized objects on the basis of the induced polarization characteristics and the electricity characteristics of the rocks and minerals. From the results of this study, it is concluded that the dual frequency induced polarization method can he effectively applied in Tibet characterized by cold weather, high altitude and severely undulate landform.
