| 摘 要： | 本文依据大地构造理论和最新研究资料对中国东南大陆岩石圈演化研究中的有关问题作了探讨，认为地体理论和大地构造相模式理论是相辅相成的；建议扬弃华夏古、特提斯构造域和太平洋构造域等可能束缚研究思路的概念；将板片构造、斜向碰撞与走滑纳入中国东南部碰撞造山带的研究内容。

| Abstract: | Based on the latest tectonic theories and attainable data, the present authors put forward their own views about the research of lithosphere tectonic evolution of SE China．The concepts of terrane analysis and the mode1 of tectonic facies, as two methods of regiona1 tectonic analysis rooted in plate tectonics, are harmonious. The former contributes to clarify the composite units of orogenic belts and their origin and development, while the latter constructs the regular pattern of formation and evolution of orogenic belts. A synthetical study of the two methods is an effective and practicable thinking in research of orogenic belts of China. The Precambrian crust materials n SE China are some palaeoslabs from Gondwana and their re-cycled materials rather than autochthonous, and they call not constitute a unified Cathaysia old landmass. The four stages collisions between microcontinents or terranes respresented by these plaleoslabs, occurring in late Proterozoic, early Paleozoic, early Mesozoic and late Mesozoic respectively, formed the multiple orogenic belts in SE China. Detailed analyses of the four orogenic belts indicate that the concepts of Tethyan system or/and Pacific system can not give a perfect definition for their subduction polarities and senses of tectonics, especially n the existence of flake tectonics which would complicate the corresponding relationship between subduction polarity and sense of tectonics. It has been verified by the research of southeastern Pujian 1ate Mesozoic orogenic belt. Oblique collision and strike-slip are more common collisional styles between plate boundaries and have been regarded as basic property of orogenic belts. This has been affirmed by the identification of oblique collision and strike-slip in the multiple orogenic belts of SE China and other areas all over the world. The authors conclude that the research of flake tectonics, oblique collision and strike-slip will extend the study domain of orogenic belts and offer a new approach to reconstruct the relationship between plate kinematics and collisional dynamics. |
