一、前言晋中南新生代裂谷系呈“S”型斜贯山西的中南部,是环绕鄂尔多斯隆起带的新生代裂谷系之一,且位于隆起带的南东缘。它是华北的重要地震带,也曾被列入找油盆地,因此进行过较详细的地质调查。但由于裂谷被第四系掩覆,其构造在地表很难查明,为此,作过多种地球物理勘查,特别是人工地震提供了丰富的地质信息。 I. Preface The Jinzhongnan Cenozoic Rift System is a “S” -shaped diagonal through the central-southern Shanxi Province. It is one of the Cenozoic rift systems that surround the Ordos uplift and is located on the southern margin of the uplift. It is an important seismic zone in North China and has also been included in oil-seeking basins. Therefore, a more detailed geological survey has been conducted. However, since the rift is covered by the Quaternary system, its structure is difficult to be identified on the earth’s surface. Therefore, many geophysical surveys, especially artificial earthquakes, have provided rich geological information.
