摘　　要：根据大巴山大地电磁(MT)区域大剖面资料,详细分析了该区的MT电性特征,并推断了本区的深大断裂及地质构造。结合地震、地质资料对大巴山褶皱带进行了进一步特征分析,研究了本区基本构造特征,划分了大巴山褶皱带及南缘构造单元,预测了该区的油气勘探前景。One long profile of the magnetotelluric （MT） soundings was used to explore the geological structures in Dabashan area. The MT geoelectric characteristics in the profile was analyzed and then applied to the interpretation of the faults, folded belts, geological structures, etc.. The seismic profile was also used to further study the geological feature. On the basis of the tectonic characteristic, the oil and gas prospects were predicted in the area.
