印支运动后,中国东南部地壳演化由地台阶段转入地洼阶段。按板块构造观点应属由岛弧型陆缘转化为安底斯陆缘,古太平洋板块直接俯冲于古欧亚板块之下,致使已固结刚化的东南陆壳,发生强烈的拱曲、断拗和空前发育的岩浆火山活动。地洼造构造特征与板块运动在时间上、空间上和基因上的一致,显示了两者之间是十分相近的。 After the Indo-Chinese Movement, the crustal evolution in the southeastern part of China shifted from the terrace stage to the diwa stage. According to the plate tectonics, the island arc continental margin should be converted into Andes continental margin. The Paleo-Pacific plate directly subducted beneath the paleo-Eurasian plate, resulting in the rigidified rigid continental crust, strong arching, Disastrous and unprecedented development of magmatic volcanic activity. The structural features of Diwa and the movement of plate are consistent in time, space and gene, showing that the two are very similar.
