立足于羌塘地体内发育的龙木错—双湖构造带最新研究进展,尝试对冈瓦纳北缘以及古特提斯洋构造演化历史进行探讨,认为特提斯从寒武纪打开,可能在早石炭世发生了向北的初始俯冲,在中晚三叠世古特提斯洋闭合,南北羌塘碰撞形成统一的羌塘盆地并开始接受新一轮沉积。但这并不是单一的威尔逊旋回,其经历的构造演化过程可能更为复杂。结合区域内岩浆活动、蛇绿岩、古生物、古地磁资料以及其他大量相关地质事实,在前人工作基础上初步构建了全新的构造演化模式。建立了古特提斯从早古生代到中晚三叠世、从大洋演化到最终闭合碰撞造山相对完整的时空演化格架,对整个特提斯演化与相关超大陆(Rodinia超大陆和Pangea超大陆)的研究具有其特殊的意义。
Based on the recent development of the Longmucuo-Shuanghu tectonic belt developed in the Qiangtang area, an attempt was made to explore the tectonic evolution history of the Gondwanaland and the Palaeo-Tethys. It is believed that Tethys may open from the Cambrian, In the Early Carboniferous, the northward initial subduction occurred. During the middle and late Triassic, the ancient Tethys Ocean was closed. The northern and southern Qiangtang collided to form a unified Qiangtang basin and began to accept a new round of sedimentation. However, this is not a single Wilson cycle, and the tectonic evolution undergone may be more complicated. Combined with the magmatism in the area, ophiolite, paleontology, paleomagnetic data and many other relevant geological facts, a new tectonic evolution model has been basically constructed on the basis of previous work. Established the relatively complete space-time evolution framework of the ancient Tethys from the Early Paleozoic to the mid-late Triassic, from the oceanic evolution to the final closed collision orogeny, and analyzed the entire Tethyan evolution and related supercontinent (Rodinia supercontinent and Pangea supercontinent ) Research has its special significance.
