The Early Mesozoic tectonic regime of the South China Block was characterized by strike‐slip movement. The northeastern South China Block dominated by recumbent folding, thrusting, and foreland imbrication. Between the North and South China blocks in southern Qinling, there was dextral transpression, but in the western South China Block, sinistral transpression took place. In central South China, sinistral transtension prevails. In contrast, both the eastern and western South China margins, composed of Precambrian basement, appears to be little deformed. These differences are due to lateral extrusion of the South China Block. Extrusion resulted from (a) an overall southerly compression (the North China Block against the South China Block) and indentation of the rigid North China Block into the weaker South China Block, (b) unconstrained South China southern margin, containing a subduction zone between the Indochina Block and the South China Block, allowing the escaped materials to be consumed, (c) an association of strongly constrained margins of the central Sichuan Craton in the western South China margin and the Southeast China Massif in the eastern South China margin, (d) structural obstacle of the Jiangnan Uplift mainly composed of the Proterozoic metamorphic basement, and (e) a previously thickened, gravitationally unstable, thermally weakened crust of the eastern Yangtze valley. The extrusion deformation began about at the beginning of the Jurassic/the end of the Triassic, and terminated at the end of the Cretaceous.

华南与华南碰撞相关的华南早中生代陆内变形挤压模型

华南地块的早期中生代构造体系以走滑运动为特征。华南东北部的块状地带，以俯冲，俯冲和前陆成岩作用为主。在秦岭南部的华北与华南地块之间，存在右旋压迫，但在华南西部的西部，发生了左旋压迫。在华南中部，以鼻窦扩张为主。相比之下，由前寒武纪基底构成的华南东部和西部边缘似乎几乎没有变形。这些差异是由于华南地块的横向挤压造成的。挤压是由于（a）整体向南压缩（华北地块对华南地块）以及刚性华北地块压入较弱的华南地块，（b）华南无限制的南缘，在印度支那地块与华南的地块之间有一个俯冲带，允许逃逸的材料被消耗掉；（c）华南西部四川克拉通中部受强烈限制的边缘边缘和华南东部东部的东南地块，（d）江南隆起的构造障碍主要由元古代变质基底组成，（e）长江东部先前变厚，重力不稳定，热弱的地壳。挤压变形大约在侏罗纪开始/三叠纪末期开始，并在白垩纪末期终止。允许消耗逃逸的物料，（c）华南西部边缘的四川中部克拉通边缘和华南东部边缘的东南地​​块的强烈约束边缘，（d）江南隆升的结构障碍由元古代变质基底组成，和（e）长江东部先前变厚，重力不稳定，热弱的地壳。挤压变形大约在侏罗纪开始/三叠纪末期开始，并在白垩纪末期终止。允许消耗逃逸的物料，（c）华南西部边缘的四川中部克拉通边缘和华南东部边缘的东南地​​块的强烈约束边缘，（d）江南隆升的结构障碍由元古代变质基底组成，和（e）长江东部先前变厚，重力不稳定，热弱的地壳。挤压变形大约在侏罗纪开始/三叠纪末期开始，并在白垩纪末期终止。（d）江南隆起的构造障碍主要由元古代变质基底组成，以及（e）长江东部先前变厚，重力不稳定，热弱的地壳。挤出变形大约在侏罗纪开始/三叠纪末期开始，并在白垩纪末期终止。（d）江南隆起的构造障碍主要由元古代变质基底组成，以及（e）长江东部先前变厚，重力不稳定，热弱的地壳。挤压变形大约在侏罗纪开始/三叠纪末期开始，并在白垩纪末期终止。
