摘　　要：文山天生桥铝土矿赋存于上二叠统龙潭组地层内,上覆地层为下三叠统飞仙关组紫红色、黄绿色泥岩、砂质泥岩。在地质工作程度高的剖面进行了激电中梯及音频大地电磁测深法,其最终反演结果与地质剖面揭露的信息吻合较好,说明激电中梯测量与音频大地电磁测深相结合的物探方法在铝土矿区是一种有效的勘查手段。The bauxite in Tianshengqiao of Wenshan are deposited inside the stratum of Longtan formation of Permian,the overlying strata is the purple-red,yellow-green mudstone,sandy mudstone of lower Triassic Feixianguan formation.The profile with high degree of geological work was explored by induced polarization IP intermediate gradient and audio magnetotelluric sounding method,the final inversion results and information showed by geological profiles matched well,this shows the geophysical exploration method that joint of IP intermediate gradient and audio magnetotelluric sounding method is an effective surveying method for bauxite mine.
