印度支那地块于早第三纪至中新世发生大规模地向东南方向走滑,同时伴随着15°顺时针旋转。青藏高原及邻区晚自垩世以来的古地磁古构造及地质年代学研究新成果,说明青藏高原岩石圈的构造演化过程,即古新世初印度板块与欧亚大陆的南缘拉萨地块碰撞,至49 Ma左右印度与拉萨地块发生全面拼合,随着印度板块进一步向北挤压,从碰撞期至16 Ma,印度支那地块沿红河大型走滑断裂发生侧向滑移;印度与“欧亚大陆”之间的构造缩短通过岩右圈板块沿着大型走滑断裂系的挤出以及板块间的消减得到调整。青藏高原大规模的岩石圈构造缩短很可能始于中新世27 Ma左右沿着早期陆块间的接合带发生。一些事实还说明青藏高原的总体隆起很可能是通过10 Ma前后和3 Ma以后多期非均匀隆升形成的。
The Indochina block swooped extensively to the southeast from the Early Tertiary to the Miocene with a clockwise rotation of 15 °. The paleomagnetic geotectonic and geochronological new achievements since the Late Cretaceous in Qinghai-Tibet Plateau and its adjacent areas show the tectonic evolution of the lithosphere in the Qinghai-Tibet Plateau, that is, the Lhasa block between the Indian Plate and the southern margin of Eurasia at the beginning of Paleocene After 49 Ma, the Lhasa massif was completely flattened. As the Indian plate further crushed northward, from the collision period to 16 Ma, the Indochina massif slipped laterally along the large red-slip strike of the Red River. India and The structural shortening between “Eurasia” was adjusted by the extrusion of the lithosphere-right lamellas along the large strike-slip faulting and the subduction between plates. The large-scale lithospheric tectonic shortening of the Qinghai-Tibet Plateau is likely to occur along the junction between the early land masses about 27 Ma in the Miocene. Some facts also show that the overall uplift of the Tibetan Plateau is probably formed by multiple non-uniform uplift after 10 Ma and after 3 Ma.
