Although much work has been recently done in China, the knowledge of the Early and Middle Paleozoic configurations of the cratonic blocks and terranes that constitute present-day Northwestern China is still inadequate. This project will study newly recognized Cambrian through Devonian strata in Tarim and Nantianshan terrane to obtain paleomagnetic poles for these time intervals to better define the apparent polar wander path for the Tarim and Nantianshan terranes. Results will help unravel the complex tectonic histories of China and Gondwana.

尽管中国最近做了很多工作，但对构成当今中国西北地区的克拉通块体和地体的早古生代和中古生代构造的了解仍然不足。 该项目将研究塔里木和南天山地体新认识的寒武纪至泥盆纪地层，以获得这些时间间隔的古地磁极，从而更好地确定塔里木和南天山地体的视极漂移路径。 研究结果将有助于揭示中国和冈瓦纳大陆复杂的构造历史。
