| 摘 要： | 东昆仑东段晋宁运动表现为一期强烈的构造热事件,不仅有碰撞型花岗岩侵入体形成,而且使基底岩系发生角闪岩相变质和变形。同位素研究表明本区晋宁运动的活动时期在957～746MaB.P.,在晋宁运动早期开始的大规模碰撞拼合在晋宁晚期达到高峰,并一直延续到震旦纪早期,它可能是全球范围内Rodinia超大陆形成时的构造热过程在东昆仑地区的反映。

| Abstract: | The Jinning movement is manifested as a strong tecto-thermal event in the eastern sector ofEast Kunlun. Not only the collision-type granitoid intrusive bodies were formed, but also the basement rockseries were subjected a metamorphism of amphibolite facies and deformation, which related to collisionbetween continental blocks. Isotope study indicate that Jinning movement was operating from 957 to 746Ma.B.P.. The large-scale collision-join began in the earlier epoch of Jinning movement, reached a hightide in the later epoch of Jinning movement and continued to Early Sinian period. It may be a reflection ofglobal tecto - thermal process, in which the Rodinia ultracontinent formed, in East Kunlun. |
