The regional tectonic map is one of the main professional maps. The Mapping methods, the division method of geological tectonic units and the main geological tectonic units are mainly discussed. The strata from Pliocene to Holocene are peeled off so as to display the Pre-Pliocene structures. In basins, isopaches are drawn for the Cenozoic deposits. The plate tectonic theory and present tectonic pattern are adopted as the priorities in tectonic division. As to the division of intraplate tectonic units, it is a revision, complement and improvement of previous dividing systems, and the nomenclature for each tectonic unit follows the current system in China. The first-order tectonic unit is plate （Pacific Plate, Eurasian Plate and Philippine Sea Plate）. The second-order tectonic unit is tectonic domain （East Asian continental tectonic domain,East Asian continental margin tectonic domain and west Pacific tectonic domain）. The Philippine Sea Plate and the west part of the Pacific Plate are called the West Pacific tectonic domain. The part of the Eurasian Plate involved in this study area can be further divided into East Asian continental tectonic domain and East Asian continental margin tectonic domain. The East Asian continental margin domain is composed of the Ryukyu island arc, the Okinawa Trough back-arc basin and the back-arc basin of Sea of Japan. The East Asian continental tectonic domain in this study area is composed of the Sino-Korea Massif, the Changjiang River （Yangtze） Massif and South China Massif. In turn, these massifs consist of basins, folded belts or uplift zones. The basins,the folded belts or the uplift zones are further divided into uplifts and depressions made up of sags and swells.展开更多

The previous tectonic maps for Asia were created in the 1960s-1970s of the last century. Since that time, the national geological surveys have compiled tectonic maps exclusively in the limits of their own state boundaries. The international cooperation of five countries since 2002 （ Russia, China, Mongolia, Kazakhstan and Republic of Korea） gave a unique possibility to join the data into a united cartog-raphic form as Atlas of Geological Maps （since 2002-Atlas of Geological Maps of Central Asia and since 2007- Atlas of Geological Maps of Northem-Central-Eastem Asia）. Both atlases include four maps： geological, tecton-ic ,metallogenic, and energy resources. Tectonic Map of Northem-Central-Eastem Asia and Adjacent Areas at scale 1 ： 2 500 000 was the key map for further compilation of the metallogenic and energy resources （ coal, oil and gas） maps. By this reason, special attention was given to showing the structure and composition of the Mes-ozoic sedimentary basins in Northern-Central- Eastern Asia as the most perspective structures for oil-and-gas and coal prospect.展开更多
