晚中生代时期，中国东南部位于日本—台湾火山岛弧的后缘。中侏罗世—晚白垩世期间，受太平洋板块朝东亚陆缘俯冲以及弧后扩张作用的影响，中国东南部广泛发育了伸展断陷盆地和火山—侵入岩岩系。盆地类型包括中侏罗世的裂谷盆地、晚侏罗世—早白垩世的火山碎屑—熔岩断陷盆地、晚白垩世—古近纪的红色碎屑断陷盆地等3种，火成岩岩系则主要由花岗岩类、双峰式火成岩、碱性花岗岩、变质核杂岩与穹隆状花岗岩等组成。盆地形成时代和岩浆岩侵位结晶时代相近，年龄峰期140~110 Ma (早白垩世)，两者紧密分布在一起，构成早白垩世中国东南部盆岭构造。文章对中国东南部晚中生代盆地和岩浆岩山岭的基本地质特征进行了归纳，对火成岩系列的岩石学和构造地质等特征以及形成中国东南部盆岭格局的制约因素进行了分析。最后，对中国东南部晚中生代地球动力学演化过程进行了探讨。

The Southeast China Block was located in the back margin of the Late Mesozoic Japan-Taiwan volcanic arc. The middle Jurassic-late Cretaceous extensional basins and volcanic-intrusive rock series are widely developed in the Southeast China region as a response of ancient Pacific Plate subduction toward the eastern Asia Continent leading the back-arc expansion. The types of basin include the middle Jurassic rifts, the late Jurassic-early Cretaceous volcanoclastic and lava faulted-depression basins and the late Cretaceous-Paleogene redbed faulted-depression basins. The igneous rock series consists mainly of granitoids, bimodal magmatic rocks, A-type granites, metamorphic core complexes and doming-shape plutons, which were formed in the early Cretaceous with a peak value of 140-110 Ma). The basins coexist together with coeval plutons and constituted the Early Cretaceous Southeast China Basin and Range tectonics. This study summarized the principal geological features of the Late Mesozoic Southeast China basin and range geomorphology and analyzed the petrological and geological structural marks and the constraint factors forming the Southeast China bansin and range framework. Finally we discussed the Late Mesozoic geodynamic process of the Southeast China region.
