中文摘要：

为研究山西韩城断裂中段西庄村-西南村一带的晚第四纪活动性,采用遥感解译、地质地貌调查等手段,对该断裂在该地区的典型断层剖面进行了分析,给出了该段断裂的展布及晚第四纪以来的地层地貌标志、活动幅度及滑动速率。研究结果表明：韩城断裂在该段普遍错断马兰黄土下部古土壤S1,最新错断马兰黄土中上部古土壤L1s并直通地表,晚更新世晚期以来仍有活动。估算晚更新世早期以来滑动速率约为0.088mm/a,晚更新世晚期以来滑动速率大于0.035mm/a。

英文摘要：

In order to study the Late Quarternary activity of middle Hancheng fault between Xizhuang Village and Xinan Village,this paper analyses the typical profile of this fault in the area by means of remote sensing interpretation and geomorphological surveys,and obtains the distribution,stratigraphic and geomorphologic marks,activity scope,and slip rate of this fault since Late Quaternary.The study results show that the faults cut through the paleosoil S1 in the bottom of Malan loess in general with a maximum cumulative distance of 6.6mand recently deform the paleosoil L1 sin the upper middle part of Malan loess right to the surface.The fault is still active since the Late Pleistocene.We estimate that the slip rate is about 0.088mm/a since the early Late Pleistocene and the rate is over 0.035mm/a since the late Late Pleistocene.
