| 摘 要： | 西昆仑塔什库尔干构造混杂岩带由古元古代基底岩片、震旦纪大陆板内裂谷玄武岩岩片、奥陶纪-志留纪复理石岩片、石炭纪-二叠纪火山弧岩片及高压变质岩片组成.根据高压变质、残余洋盆及岩浆孤的形成时闯进行综合判断,混杂岩带形成于早古生代.该混杂岩带的发现对于确立康西瓦断裂带的性质和认识西昆仑地区的大地构造演化历史具有重要意义.进一步表明西昆仑地区在早古生代曾发生过板块俯冲和碰撞,并暗示麻扎-康西瓦断裂可能代表了原特提斯洋-古特提斯洋俯冲消减并最终闭合的界线.

| Abstract: | Taxkorgan West Kunlun tectonic melange belt by the composition of the Paleoproterozoic basement rock-chip sector, the mainland Sinian plate rift basalt rock film, Ordovician-Silurian flysch rock film, Carboniferous-Permian volcanic arc rock-chip and high-pressure metamorphic rocks. According to the high-pressure metamorphic, the remnants of oceanic basin and the formation of magmatic arc of time to determine a comprehensive, mixed with melange belt formation in early Paleozoic. The melange belt Kangxiwar for the establishment of the nature of the fault zone and in the West Kunlun tectonic evolution of the research is of great significance, which indicates that further discoveries in the West Kunlun region in early Paleozoic there have been plate subduction and collision course , and hinted that the mazar - Kangxiwar fault may represent the original Tethys - the ancient Tethys subduction and final closure of the line. |
