【摘要】 断裂活动的横向迁移是断裂发展演化过程中的一种普遍现象 .在渭河盆地这种现象也较为常见 ,特征比较典型 .本文以蓝田南侧王顺山山前断裂活动向其北侧的骊山山前断裂和渭南塬前断裂的迁移 ,骊山凸起西北侧临潼—长安断裂带内大鲍陂—牛角尖次级断层的强烈活动向神峪寺—肖家寨次级断层的迁移 ,以及渭河盆地中西部宝鸡与泾阳间一系列北西向断裂活动的横向迁移为例 ,分析和讨论了它们各自的迁移时段及迁移过程 ,为充分认识这些地区的构造发展和地貌演化历史 ,深刻把握渭河盆地内最新的控制性活动断裂 ,更加切近实际地估计每一条断裂的地震危险性提供了帮助 .更多还原

【Abstract】 Lateral migration of fault activity in Weihe basin is a popular phenomenon and its characteristics are also typical. Taking the activity migrations of Wangshun Mountain piedmont fault toward Lishan piedmont fault and Weinan platform front fault, Dabaopi Niujiaojian fault toward Shenyusi Xiaojiazhai fault, among a serial of NE trending faults from Baoji city to Jingyang County as examples, their migration time and process are analyzed and discussed in the present paper. It is useful for further understanding the structure development and physiognomy evolution history of Weihe basin.更多还原
