FEATURES OF GEOPHYSICAL FIELDS AND GEODYNAMICS OF THE SEA AREAS OF CHINA
Liu Guangding (Institute of Geophysics, Academia Sinica)
In the period of 1960—1990, an extensive geological and geophysical investigation was carried out in the sea areas of China. Based on the materials obtained, the "Geological-Geophysical Serial Maps of the China Seas and Their Adjacent Areas" (1:2000 000) have been compilted. In fact it is a systematic summary of the geological and geophysical work of the sea areas of China in the past 30 years. In this paper, the author explains the guiding thinking and methodology of the compilation of the serial maps and then briefly deals with the characteristics of geophysical fields and geodynamics, stratigraphy, fracture systems and magmatism. On that basis the tectonic evolution of the China Seas is discussed.
