| 摘 要： | 通过对钻孔资料和野外露头获得的运城盆地第四纪古河道等资料的分析，发现涑水河在第四纪期间发生了多次由东向西的迁移，第四纪沉积地层的不连续、沙渠河阶地的错断变形和鸣条岗东南侧地裂缝的发育等情况说明鸣条岗高地为一活动的地垒构造。通过分析对比古河道迁移和鸣条岗地垒的活动情况．得出古河道的迁侈是鸣条岗地垒活动结果的结论。

| Abstract: | Based on the analvsis of borehole data and Quaternarv old channel data from field outcrops in YunchengBasin,it is found that the Sushui River migrated repeatedly from the east to west in the Quaternary period.The discontinuities of the Quaternary sedimentary strata,the strain-slip deformations of the Shaqu Riverterrace and the development of the ground fissures in the sourtheast side of Mingtiaogang show that Ming-tiaogang Highland is a active horst structure. Through the analysis and comparison for the old channel migra-tion and activity of Mingtiaogang horst,the conclusion is obtained that the old channel migration resultedfrom activity of Mingtiaogang horst. |
