For a long time a lot of the models about the tectonic evolution and the orogenic architecture of the Paleo Asian tectonic domain are suggested by many famous geologists. However, there are large divergence of the views, especially about both the space distribution and the closing time of the Paleo Asian Ocean. Based on the intrusive tectonic map of China with the scale of 1:2500, 000, by this paper we would like to join the discussion. (1) The formation of the intrusive arc, and the collisional as well as the postorogenic igneous petrotectonic assemblages is occurred progressively younger from west to east with time, and the trend lines of the main tectonic zones is developed from near east—west in the west to near north—south directions in the east, both of which is suggested the transition of the Paleo Asian Ocean closing to development of the Pacific tectonic domain. (2) The broad trench—arc—basin system developed at the southern margin of the Siberia craton situated in the north of the main oceanic basin; the passive continental margin at the west, and the narrow trench—arc—basin system in the middle, as well as the active continental margin at the east, respectively, developed at the northern margin of the Tarim—North China craton. (3) Both the remnant arc and the oφ since Pt3 is scattered within the main arc, and is regarded as the basement beneath the main arc. (4) The classical “massif” in the orogenic zone is considered to be the remnant arc by this paper, because they are intrusive arc formed in the early stage during the oceanic subduction. (5) The main oceanic basin is recognized from three signs by this paper, （a) The closing of the ocean is latest, （b) The oceanic subduction is bidirectional when the active arc at both the sides, or is developed at one side when one side is active continental margin, and the other side is passive continental margin, （c) The long live and the residue ocean of the Mediterranean sea type are developed as the early stage of the continent—continent collision. (6) A lot of both the intrusive arcs and the oφ during Pt3—T support the formation of the large amount of the juvenile continental crust by Sngor et al., as well as is corresponded to the positive value of the εNd(t) for the granites, which, in turn, is suggested to be formation of the large amount of the oceanic subduction resulted in the cooling of the mantle, and the adding eclogites into the mantle, finally, the high density mantle flow is formed as the dynamic source for the closing of the Paleo Asian Ocean and then the collision between the Siberia and the Tarim—North—China cratons.
