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 from 1: 50000 geologic mapping of active faults, the distribution and internal structure of active folds in Yishu fault zone and its relationship with active faults were discussed. The active folds of Yishu fault zone develop between the faults F1 and F2 and are beaded along with the F5 fault distribution. They began to form in the Tertiary Period and formed mainly in the late Quaternary. They are active folds. Active folds and active faults are two forms of formation in the D-shear zone.
