The Paleomagnetic Research And Kinematics Characteristic Discusse Of China’s Major Blocks During Late Paleozoic To Mesozoic

Paleomagnetism is well known as a method for geotectonic evolution. paleomagnetic data can use to quantitative and half quantitative reconstruct paleogeographic of continental plates. paleomagnetic data also can use for the study of kinematical evolution，discuss collision and collage and separation era，provide foundational information for the study of geodynamics evolution，guidance solid mineral and oil and gas resources exploration and other areas of work.On the basis of previous work，this research collect and organize paleomagnetic data in China continent. we also analysis and explain paleomagnetic data of Yangzi， North China， Tarim， Qiangtang， Gangdese and Himalaya block during Late Paleozoic to Mesozoic. In the quantitative restrictions of paleomagnetic data and the qualitative constraints of other geological information，we discusse the kinematic characteristics of China’s major blocks during late Paleozoic to Mesozoic and the evolution of eastern Tethys. The conclusions as follows：(1) In early Paleozoic the main block of China continental are discrete block in the ancient Tethys.(2) Late Paleozoic is the main period for the major China blocks fast moving northwards and gradually gathered together.(3) Early Mesozoic is the main revolution period of China mainland blocks.(4)Late Mesozoic is the period of rotating and adjusting relative position between blocks.(5) The Paleo‐tethys opened in Late Carboniferous，closed in early Triassic， the largest basin in early Permian；The Mid‐Tethys opened in late Permian，closed in early Cretaceous，the largest basin in late Jurassic；Neo‐Tethys opened in late Triassic，closed in late Eocene，the largest basin in early Cretaceous.
