According to the study of magnetotelluric sounding data in Qiannan-Guibei area, units of different district condtructs were revealed clearly and structural existence of basin and mesa as well as its scope were announced to public.The result shows: In marine-facies area of south China,features of resistivity varies greatly with different lithofacies and lithofacies can be divided by features of resistivity. Meanwhile,through the features of electric fabric of each lithofacies, we can study to scribe layer and reveal some hydrocarbon potential structure. As a living example,hydrocarbon potential structure of Zhe'xiangjie has been turned up In this way.
