| 摘 要： | 对山东省沂水县大水场断层剖面的断层泥带进行了野外观测和ESR 测年。断层泥的ESR年龄与由其穿插关系等判断出的断层活动次序相符。各断层泥的ESR 年龄显示出大水场断层经历了两个活动较频繁的时段,即0-25～0-28Ma B-P- 和0-45～0-55Ma B.P

| Abstract: | Along the Dashuichang gouge profile of the Yishu fault zone, there are ten divided gouge stripes based on colors and textures of the gouge Thirteen samples for ESR dating have been collected from the various gouge stripes ESR dates of these samples range from 240ka to 530ka B P , and concentrated on two time intervals of 240～310ka and 410～530ka, respectively It means that there might be two major active episodes on the fault during the Quaternary period. The ESR dates of gouge quartz samples are co |
