CONSTRAINTS OF THE MESO-CENOZOIC GLOBAL VELOCITY-FIELD OF LITHOSPHEREON THE TECTONIC EVOLUTION OF CHINA AND ITS ADJACENT AREAS

Geodetic ranging and geophysical survey provide the present-day global velocity field of lithosphere. Data of sea-floor magnetic anomalies, hotspot migrations and continental paleomagnetism were used to set up the palaeo-velocity field of lithosphere in geological history. And th e Meso-Cenozoic global velocity field of lithosphere was established b y combining the palaeovelocity vectors with the present-day, velocity, vectors of major lithospheric blocks. These darn mag, lay very import ant constraints on analyzing the tectonic setting of China, the Meso-C enozoic intracontinental orogenesis, rifting process, strike-slip faul ting, continental earthquakes and the related geodynamics of China and its adjacent areas, which leads to some new conclusions about the cau se of the Meso-Cenozoic tectonics of Asia.
