| 摘 要： | 福建长乐—东山构造带是我国东南沿海中生代NE向线性构造带的一部分。从西向东分为三个亚带:福清—云霄钙碱性火山岩带(J_3);长乐—东山NE向韧性剪切带(K_1); 平潭—东山变质地体(P_z—J_3)。火山岩带以浅层构造、脆性挤压变形为特征。变质地体为一外来体,以深层构造、多期(即前J,J,K_1)叠加变形为特征,并于J_3末增生到欧亚大陆边缘。韧性剪切带是叠加在变质地体增生带上,为一左行平移简单剪切带。

| Abstract: | The Changle-Dongshan structural zone is a part of the Circum-West PacificMesozoic NE-trending linear structural belt in the southeastern coast of China. Itis divided into three subzones from west to ease: the Fuqing-Yunxiao calcalkalivolcanic rock zone, Changle-Dongshan ductile shear zone and Pingtan-Dongshanmetamorphic terrane. The volcanic rock zone is characterized by Late Jurassicshallow-level brittle brachyfolds. The metamorphic terrane is an exotic terrane.The protoliths of Early Paleozoic age had been supperposed by polyphase deforma-tion (Pre-J, J, K_1). The main phase witnessed the ductile thrust shear deformationfrom NW to SE in the Jurassic. The metamorphic terrane accreted to the marginof the Eurasian continent in the terminal Late Jurassic. The ductile shear zone isan Early Cretaceous sinistral strike-slip simple shear zone, superposed upon theaccretionary zone of metamorphic terrane. |
