Geological map, as an efficient tool to present and summarize geological survey results, is a kind of geological information indispensable for economic and social development, and has attracted great attention from the government and the public all over the world. Qingdao Institute of Marine Geology has been complicating the serial maps of geology and geophysics on China Seas and Land on the scale of 1:5M since 2008. It is important to compile a piece of map including Chinese mainland and China Seas and the adjacent land and sea area. The serial maps compilation was under guidance of block tectonics, and based on various data and survey results of geology and geophysics on China seas and land over the past sixty years. The compilation has three main purposes: realizing the splice that includes theoretical basis, technology and method of maps of geology and geophysics on China seas and land; reflecting the status of survey and research of basic geology and tectonic framework of the study area; and exhibiting the growth, development and collision of different blocks and the formation of Pangea on China seas and land since Paleozoic, revealing emphatically the evaluation process of Chinese mainland that from "higher in the east, lower in the west" to "higher in the west, lower in the east" since the Indo-China movement. The serial maps can provide service to geological work deployment which would be helpful for the policy-making body. Meanwhile, the serial maps can also be used as a basic map for mineral resources exploration and resources and environment studies. And, the methods we used in the compilation of the serial maps are introduced as a new try to solve the problems we had met.
