青藏高原是建立新的大陆动力学理论的最佳天然实验室。冈瓦纳与欧亚大陆界线研究是地学界持续的研究热点，界线位置、性质的确定在特提斯洋演化过程研究中占据最为重要的位置。拉萨、南/北羌塘地块被认为是解决这一科学问题的关键地区。本项目在本人已参与完成的青藏高原古地磁研究项目的基础上，拟将标准古地磁学研究手段与火山岩同位素年代学、磁性地层学及岩石磁学、岩石磁组构分析等方法有机结合，以青海省格尔木市唐古拉山乡周琼玛鲁二叠纪那益雄组火山岩连续剖面为具体研究对象，开展精细古地磁学研究，以期获得羌北地块东段具有精确年龄控制的高质量古地磁数据。并结合前期在羌北地块西段二叠纪沉积地层中获得的可通过褶皱、倒转和烘烤检验的古地磁数据，确定羌北块体晚古生代的古地理位置及其运动学特征，研究其与拉萨、南羌塘地块之间的碰撞拼合过程，为恢复青藏高原古特提斯演化历史，厘定冈瓦纳与欧亚大陆的界线、碰撞时限及古地理位置提供定量约束。

The Qinghai-Tibet Plateau is considered to be ideal natural laboratory for building a new theory of continental dynamics. The plate boundary between the Gondwanaland and Eurasia plates, which play an important role in understanding plateau internal structure and evolutionary history of the Tethys, remain hotly debated. Lhasa, south / north Qiangtang region in the Qinghai-Tibet Plateau may be a key place to study these problems. In order to obtain a high quality paleomagnetic data with accurate age control in northern Qiangtang block, this project intends to carry out a refined paleomagnetic studies on the permian volcanic rocks in Zhouqiongmalu areas of Tanggula township, east China. This studies based on the accumulation of the Qinghai-Tibet plateau paleomagnetic research we has completed, and associates research techniques of paleomagnetism, magnetostratigraphy, volcanic chronology, rock magnetism and magnetic fabric analysis. Combined with the early reported paleomagnetic data from the permian sedimentary strata from the western part of the northern Qiangtang Range, which primary origin of the magnetization is confirmed by positive fold-, reversal-, and baked contact tests, this project aim to reconstruct paleogeographic location and kinematic characteristics of the northern Qiangtang block in late Paleozoic, ascertain the collision process between Lhasa and south / north Qiangtang blocks, determine the plate boundary of Gondwana and Eurasia plates.
