太行山南缘新生代的隆升与断陷过程

作者通过太行山南缘夷平面、河流阶地、山前盆地和中新生代断裂的调查研究,揭示了太行山南缘新生代的断陷与隆升过程,认为太行山南缘地区新生代以来的构造活动以断裂的断陷、隆升为特征,分为三个相对稳定夷平时期和三个快速隆升阶段,形成三级夷平面.第四纪以来的快速隆升过程可进一步划分为六次相对快速抬升和六个相对稳定堆积时期,形成六级阶地.古近纪断陷活动强烈,第四纪除山前断裂以外,其它断裂未见活动.

The Cenozoic Rifting and Uplifting Process on the Southern Margin of Taihangshan Uplift

Based on an investigation into the planation surfaces, terraces, piedmont rift basins and active faults, this paper deals with the process of rifting and uplifting on the southern margin of Taihangshan uplift. It is considered that the tectonic activities on the southern margin of Taihangshan uplift have been characterized by rifting and uplifting of faults since Cenozoic, and these activities can be divided into three relatively stable planation periods and three rapid uplifting stages, which resulted in the formation of three planation surfaces. The rapid uplifting process can be divided into six relatively rapid uplifting and six relatively stable accumulation stages since Quaternary, with the development of six river terraces. Rifting was violent in Paleogene. The faults were not active in Quaternary except the piedmont faults.
