摘　　要：根据长乐 -南澳变质杂岩的原岩恢复、同位素年龄和古生物资料 ,提出华南东部震旦—志留纪的大地构造属性是由大陆边缘弧和弧背盆地构成的华南造山带。认为华南大陆边缘弧和弧背盆地是在太古—元古宙大陆壳上形成的 ;According to protolith formation,isotopic age and fossils in the Changle Nanao metamorphic complex in Fujian and Guangdong,the Sinian—Silurian geotectonic attribution of Southeast China should be an orogenic belt made of a continental marginal arc and a retroarc basin formed on the Archaeozoic—Proterozoic continental crust,and no Sinian—Silurian oceanic basin within the South China block.

关 键 词：大地构造属性 大陆边缘弧 弧背盆地 震旦-志留纪 华南地区
