摘　　要：利用１∶５万活断层地质填图获得的有关资料，初步讨论了沂沭断裂带活动褶皱的展布、内部结构以及与活动断层的关系。沂沭断裂带活动褶皱发育在Ｆ１、Ｆ２断层之间，呈串珠状伴随Ｆ５断层展布，开始形成于第三纪时期，主要形成于第四纪晚期，属活动褶皱。活动褶皱和活动断层是在右旋挤压剪切带中形成的两种构造形式。Based on the data obtained by 1∶50000 geological mapping for active faults, we preliminarily discussed the distributions of active folds in the Yishu fault zone, their inner structures and relations to active faults. The folds in the Yishu fault zone developed between F 1 and F 2 faults and spreaded in a string of beads and with F 5 fault, and were formed first in Tertiary and then mainly in late Quaternary, so they are active folds. The active folds and active faults are two kinds of structures formed in rightlateral compres sional shearing zone.
