| 摘 要： | 结合黔南-桂北地区大地电磁测深(MT)区域大剖面资料的分析,划分了不同的地质构造单元,揭示了盆、台结构的存在并圈定了其范围.结果表明:在我国南方海相地区,不同相带沉积岩相电阻率总体特征存在明显的差异;利用大地电磁测深的电阻率总体特征可以进行相带划分;根据各自相带中不同的地电结构特征可以研究标志层及局部构造圈闭.

| Abstract: | 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. |

| Keywords: | Marine-facies of south China Magnetotelluric sounding Lithofacies dividing Static correction Interpretation by backward deduction |
