华南地块晚元古代至中生代沉积盖层显示了复杂构造图案,不同时期不同性质构造作用的交织,限制了对区域构造运动规律的了解和显生宙视极移轨迹(APWP)的建立,也产生了对其区域大地构造性质的不同认识.本文提供了古地磁和构造分析的初步解释:(1)扬子克拉通中部和东部的构造图案可能主要是由于中生代造山运动时期沉积盖层的滑脱造成;(2)第三纪印度大陆与欧亚板块的碰撞导致了华南地块西部和西南部广泛的局部旋转;(3)中国东南部显生宙结构模式是中古生代中期加里东造山运动和中生代中期造山运动的结果.
The late Proterozoic to Mesozoic sedimentary cover shows the complex tectonic pattern in South China Block. The interweaving of different tectonic functions in different periods limits the understanding of regional tectonic movement and the establishment of Phanerozoic Polar Moving Trajectory (APWP) (1) The tectonic patterns of the middle and eastern Yangtze craton may be mainly caused by the detachment of sedimentary cover during the Mesozoic orogeny ; (2) the collision of the Tertiary Indian continent with the Eurasian plate resulted in widespread local rotation in the western and southwestern parts of South China; (3) the Phanerozoic structural model in the southeastern part of China is the Middle Caledonian orogenic Mesozoic Mesozoic Mid-term orogeny results.
