| 中文摘要:华南主要构造特征为欧亚大陆边缘地壳生长和大陆增生。华南为一联合大陆，前寒武系基底由太古宙与元古宙岩石组成，元古宙有科马提玄武质绿岩和堇青石花岗绿岩。地壳的地球化学组成，从长尺度的时间函数上观察，具前进演化趋势，为原始→亏损→富集地幔→大陆地壳。核－慢分异发生在地球历史早期，而大陆的增生一直持续到现在。大陆边缘裂解构造是华南构造演化的主要形式，幕式地幔柱构造是该区地壳生长的主要动力机制。扬子－特提斯构造域为稳定、冷的地幔块，太平洋构造域为活动的热地幔软块。 |

| Abstract:The South China continent located on the southeast margin of the Eurasia plate is an active continental margin, which is characteristiced by the crustal and obvious lateral uncontinuation。 As the continent-ocean trasition zone the South China continent is also the active tectonics zone ofearth’s core-mantle material transmission and the obvious area of the mantle migrating and mantleplume growing as well as global act-catastrophism, The green stone occurring on the South Chinacontinent was formed from 2000Ma to 1000Ma and its geochemical composition shows a progres-sive evolution tendency i.e. from original mantle to depted mantle to enricher mantle. Gravity sub-sidence and hot point volcanism is controlled by the ultra-mantle plume and inplate continental mar-gin breakup belt. |
