| 摘 要： | 临潼-长安断裂是渭河盆地内部骊山凸起与周至-户县凹陷之间一条重要的边界性断裂。通过大范围自然冲沟、人工取土场、道路开挖边坡和路堑的野外观察,新发现临潼-长安断裂露头40余处。基于各露头不同年代古土壤标志层错距的量测,获得了晚始新世以来该断裂的位移分布。第四纪以来的断层位移分布显示出该断裂中段断距较大,活动较为强烈

| Abstract: | Lintong-Chang'an Fault is an important boundary fault between Lishan uplift and Zhouzhi-Huxian depression in Weihe basin.By the field survey to the natural gullies,the earth fetching areas,and the excavated slope and chasm for road foundation,we discovered 40 outcrops of the Lintong-Chang'an Fault.According to the measurements of dislocation of the various periods' paleosoil horizons,we get the Quaternary dislocation distribution of the fault,which shows that the fault dislocation in the middle segment is the biggest,so is its activity along this segment. |
