一、前言运城-侯马裂谷盆地是山西新生代“S”型裂谷盆地之一,位于“S”型构造的南段,是由晋西南的原运城裂谷、侯马凹陷与夹于其间并与之平行的纵向隆起——峨嵋隆起组成。其形成时间相同,成因上相互关联,原为一个构造,后期才被隔开,依构造分析,三个平行的相关构造可列为次级构造一并纳入统一的构 I. Preface The Yuncheng-Houma rift basin is one of the “S” type rift basins in Shanxi Cenozoic and located in the southern section of the “S” structure. It is composed of the original Yuncheng rift in the southwest of Shanxi Province, the Houma sag, In the meantime and parallel to the longitudinal uplift - Emei uplift. The formation of the same time, the cause of the interconnected, originally a structure, only later separated, according to the tectonic analysis of the three parallel related structures can be classified as secondary structure into a unified structure
