摘要
As the development of marine geological surveying cause, it was greatly necessary for mapping the new geophysical maps sets in marine regions. The 1∶100 million geophysical maps sets, in East China Sea, was grouped by Free air gravity anomalies maps, Bouguer gravity anomalies maps, magnetic anomalies maps, surface sediment distributing maps, and regional structuring maps. The digital mapping techniques were used to assimilate and standard the new and old literatures, and the large scale new maps were obtained in this study. Additionally, based on the study results of geophysical maps sets, the study has summarized the geophysical field characteristics, surface sediment distribution characteristics, and then, the regional tectonic units were divided of East China Sea.
