| 摘 要： | 根据广州瘦狗岭断裂带变形历史的野外地质证据以及40Ar／39Ar法和热释光法构造年龄数据，将其划分出晚三叠世-早侏罗世韧性拉伸剥离变形期，中侏罗世韧性挤压逆冲变形期，晚侏罗世末-早白垩世初脆性断裂、硅化作用期，晚白垩世-老第三纪同沉积正断层活动、硅化作用期，老第三纪晚期左行平移兼正断层活动期和第四纪正断层活动期。对该断裂带的变形期次与区域构造演化的联系进行了讨论。

| Abstract: | According to the field geological evidence and the 40Ar／39Ar and thermoluminescence chronological data the faulting deformation history of the Shougouling fault zone in the Guangzhou area is divided into 6 stages of deformation， that is， the stage of ductile extension detachment in the Late Triassic－Early Jurassic， the stage of ductile compressive thrusting in the Middle Jurassic， the stage of brittle fracturing and silicification in the terminal Late Jurassic－initial Early Cretaceous， the stage of synsedimentary normal faulting and silicification in the Late Cretaceous-Paleogene， the stage of sinistral normal-strike slip faulting in the late Paleogene， and the stage of normal faulting in the Quaternary． The relationship between the stages of deformation and the regional tectonic evolution is also discussed in this paper． |
