晚古生代是地球演化历史上一个地幔柱发育、古生物集群性死亡、Pangea超大陆形成的重要地质时期。本项目将以出露于福建、广东、海南岛、湘南、赣南等地的石炭系-二叠纪的花岗岩/花岗片麻岩、火山岩、变质岩以及沉积岩中晚古生代碎屑锆石作为研究对象，研究华南晚古生代造山带的形成和演化过程。通过野外调查和室内研究确定华南晚古生代岩浆活动和变质作用分布的范围；利用锆石、独居石、金红石和榍石等矿物的U-Pb定年，精确限定晚古生代岩浆活动和变质作用的时间和/或期次；根据岩石学、地球化学和Nd-Hf-O同位素分析，确定岩浆岩的成因和它们形成的构造背景；确定变质岩的形成条件和PTt轨迹，并反演变质作用发生的环境。将这些研究成果与晚古生代沉积环境变化相结合，讨论华南东南部晚古生代造山作用的性质和类型，建立造山过程与不同阶段岩石成因间的关系，揭示华南晚古生代造山作用与Pangea超大陆的形成和裂解之间的内在联系。

Late Paleozoic time is an important geologic period during long evolution of the earth, when wide large igneous province (related to plume) was formed, supercontinent Pangea was assembled and Variscan orogeny occurred over the Europe and North America. This project will study the late Paleozoic orogeny in the southeastern South China using samples of granites/granitic gneisses, volcanic rocks, metamorphic rocks and detrital zircons in the sedimentary rocks in the Fujian, Guangdong, Hainan Island, southern Hunan and southern Jiangxi provinces. Based on the field survey, petrologic and geochemical studies, geochronological dating of accessory minerals and analyses of metamorphic and sedimentary environment, this project will determine the distribution area and accurate ages (or episodes) of late Paleozoic magmatism and metamorphism, the origin and tectonic setting of igneous rocks, the environment of metamorphism, and the nature and type of late Paleozoic orogeny in the South China, and then reveal the relationship between the orogeny in South China and the assembly and breakup of the Pangea supercontinent.
