| 摘 要： | 昆仑-秦岭带加里东旋回的洋盆不是从元古代继承下来的．而是由寒武纪裂谷发展而来的，它在志留纪即宣告封闭；昆仑石炭纪一二叠纪海底裂谷带或可能的小洋盆，在晚二叠世前已经消失，三纪时昆仑-秦岭带只有海，而没有洋。因此，印支造山运动并不是洋盆消失后的陆-陆碰撞造山，而是陆-陆叠复造山(大陆壳消减造山)作用。

| Abstract: | The Caledonian Kunlun-Qinling oceanic basin was not a successor of the Proterozoic oceanic basins, but came from a rift in the Cambrian, and was closed during the Silurian. The Carboniferous-Permian Kunlun seafloor rift or small oceanic basins had disappeared before the Late Permian. In the Triassic, there was no ocean, but just a sea in Kunlun-Qinling. Therefore, the Indosinian orogeny was not a continent-continent collision orogeny after oceanic basin disappeared, but a continent-continent superimposed orogeny (i.e. continental crust subduction one). |
