| 摘 要： | 本文简单总结与介绍了怀柔—密云境内,石城断裂的规模、性质与活动性。初步认为该断裂属脆韧性剪切带,与云蒙山岩体上侵有关,早期压性,晚期显张性,属非全新世活动断裂,对工程影响程度低。

| Abstract: | The scale,nature and activity of the Shicheng fault in Huairou-Miyun area are introduced in this paper.This fault is basically considered as a brittle-ductile shear belt,and related to Yunmengshan rockbody upwards intruding.It shows compression nature in the early stage,extension in the late stage.It does not belong to Holocene Epoch active fault,which little affects the engineering construction. |
