摘　　要：这里介绍了大地电磁测深在色林错-申扎北剖面的应用,根据电性特征对盆地边界、基底埋深和盆地基本构造格架给出了初步认识。分析表明:色林错地区表现为"南隆北坳"特征,中北部凹陷最大深度接近5km,南部隆起部分基底埋深小于2km,发育郎山组和多尼组地层,盆地内发育多条断裂,控制了盆地形态。The application of magnetotelluric sounding in the north section of the Selincuo - shenza line is introduced in this paper.A preliminary understanding of basin boundary,the basement depth and basic tectonic framework of the Cuoqin ba-sin have been given according to the electrical characteristics.Analysis shows that the region of Selincuo the depth of the basin appears higher in the south and lower in the north,the maximum depth of north-central sag is close to 5 km.The southern uplift of basement buried depth is less than 2 km.The main stratum of this area is Langshan group and Duoni group,and there are multiple faults develop in Cuoqin basin,which control the form of the basin.
