| 摘 要： | 华南大陆记录和保存了自太古代至今大陆生长层完整的历史过程.以杨子克拉通为核心，地壳不断向东南生长，古扬子块前寒武系以灰色片麻岩、古元古代科马提岩绿岩、新元古代蛇绿岩、绿岩为特征，为相对稳定高速高阻冷的残存地幔“残烃柱”；而沿海一带火成岩以中、新生代壳－幔混合源火山－侵入杂岩、碱性花岗岩和正长岩带以及不同类型的玄武岩类为特征，为相对活动低速高导热的超地幔柱．巨型裂解构造是物质热传输的主要形式，地幔柱迁移是华南大陆构造演化的原动力．

| Abstract: | The complete historical processes of the crust growth from the Archaean to the Cenozoic eras are recorded and remained in South China continent. The crust, which is centered on the Yangtze craton, extending to the southeast. In the Yangtze block, Precambrian bases, which are composed of gray gneiss, early Proterozoic komatiitic greenstone, late Proterozoic ophiolite, greenstone, represent cool “residual hydrocarbon column” of the residual mantle with the features of relative stable, high-velocity, high-resistivity. Along the coast the igneous rocks, which are characterized by the Mesozoic-Cenozoic volcanic-intrusive complexes of crust-mantle mixed sources, alkaline granitic and syenitic belts as well as basalt of various types, represent the hot super-mantle plume with relative activity, lower-velocity, high-conductivity. The super-breakup tectonics is regarded as the main manner of heat conduction for materials. The original dynamics of tectonic evolution in South China continent is drived from migration of mantle plume. |
