摘　　要：大地电磁测深(MT)为地球物理勘探方法之一,本文通过对YF地区MT资料的解释研究,系统总结了电性结构在垂向上的组合类型分为"三低两高"Ⅰ型、"两低一高"Ⅱ型及"三低一高"Ⅲ型;划分出三种类型在平面上的分布特征及对印支面之下地层的解释;预测中、上古生界的残存状况,为油气勘探选区选带等地质综合评价提供依据。MT is a geophysical survey method. Based on interpretation of MT data on the YF area, this paper systemati- cally summarized three vertical combination types for a conductive structure, i.e., ＂three lows and two highs＂I, ＂two lows and one high＂II and ＂three lows and one high＂ III,introduced their planar distribution features and their interpretation of stratigraphy beneath the Indosinian plane,providing a basis for prognosis of middle and upper Paleozoic residual conditions and for geological comprehensive assessment such as choosing oil and gas exploration areas or zones.
