Characteristics of Zhangyuan Structure Belt in the Northern Margin of Jiangnan Orogen
详细信息   
摘要
///The Zhangyuan structure belt is a regional ultra-crust faulting belt intensely superimposed by Indosinian-Yanshanian thrust-strike slip brittle fault, characterized by NW-SW-trending ductile structural deformation mingled with Neoproterozoic mafic rocks. The Zhangyuan structure belt and Neoproterozoicvolcano-sedimentation formation distributed on both sides of the belt formed in structure-sedimentary environment related to continental margin and tectonic plates. To the south was sedimentary system of rifting sea basin, and to the north was the sedimentary system related to the continental margin volcano arc. Therefore, the Zhangyuan structure belt is characteristic of abyssal-bathyal sedimentation. The Zhangyuan structure belt connects the Fuchuanophiolite belt in northeast and Jingdezhen-Yifeng deep-large fault in southwest, and constituted an important part of subduction-collision collaged belt of continental margin oceanic basin in the northern margin of Jiangnanorogenduring Early Neoproterozoic, which is represented by the Fuchuanophiolite belt.
