Longpan deformation slope lies at the right bank of the strath in Jinsha River.The areal geology tectonics here belongs to the Zhongdian-Longpan-Qiaohou faults belt region,the tectonic structures in this area are complicated and blurry.In order to get to the bottom of the tectonics,multifunctional V6A system in CSAMT method is applied.Case studies in this area show that CSAMT method with V6A system is an effective approach to explore perdue faults under quaternary stratum in high mountains and steep gorge area.By interpretation the CSAMT and engineering-geology exploration information synthetically,the tectonic pattern of Longpan area is put forward for the first time in this paper,and the conclusion is the base of analyzing the stability of Longpan deformation slope.
