| 摘 要： | 针对扬子东南缘浙赣地区地质构造特征，通过研究中生代的构造分层、盆地演化、火山活动构造环境等，分析了研究区中生代构造环境，认为研究区中生代盆地演化经历了由近东西向、北东东向向北东、北北东向构造方向的转变和由挤压-拉张-挤压-拉张的构造环境变化；构造体制环境从晚侏罗世开始，到早白垩世早期基本完成转换过程。伴随构造环境的转变，研究区内形成了中生代不同类型的盆地。

| Abstract: | Basing on the study of Mesozoic structural layers and evolution of basins as well as tectonic setting of volcanism in Zhejiang and Jiangxi Provinces ,southeastern margin of the Yangtze Platform ,it is clarified that the evolution of Mesozoic basins of the studied area experienced a transformation of structural grain from nearly E-W or NEE-SWW to NE-SW or NNE-SSW ,and aslo a change of tectonic setting form compression to tension to compression and to tension ;that the transformation of tectonic regime and tec-tonic setting started at Late Jurassic and basically ended in the early stage of Early Cretaceous .Accompa-nied with the transformation ,Mesozoic basins of different types were formed in the studied area . |
