Based on the summary of newest progresses of global gravity field models, isostatic models and flexural theory of Hthosphere and making used of global gravity model (UTCSR GRACE/GFZ EIGEN-GRACE), First, I calculate geoidal anomalies with different degrees and orders, isostatic residual geoidal anomalies of Hthosphere and horizontal stress distribution in Chinese mainland and vicinity and make an interpretation with multi-levels isostatic equilibrium. Secondly, combination with surface geology and others geophysical data, I analyze detailed structure of lithosphere within various segments of the central orogenic system, respectively. Then, On the basis of making a comparative analysis with among East-Asian tomography, anomalies of geoid and satellite magnetic field for lithosphere and gravity and aeromagnetic, I propose a the lithospheric structural framework model for the Chinese mainland and adjacent area, specially the COS.

The lithospheric mantle of the Chinese continent, as a whole, is in compressive tectonic regime. 2. The lithosphere of eastern portion of the Chinese continent, being in extensional regime for level-shallow and motion eastward but westward dipping imbricated subduction that formed by high- and lower velocity slabs within lithosphere, suggests that it is in compressional regime in deep levels as a whole.
岩石圈大地水准面异常、水平应力场和P波地震层析等显示,中国东部岩石圈浅层次向东运动,处于相对伸展状态,而深层次高、低速板片向西叠瓦式俯冲形成挤压构造背景,以部分脱耦形式实现不同深度层次之间的调节。

Based on the regional tectonic evolution, combined with the high precision isotopic ages from this paper and other geologists, we have some new acquaintances as follows: 1 There has no Caledonian granite belt distributed in north margin of North China Craton. So, the traditional evolving model of North China Carton, which formed on this idea and the acquaintance about the collision of North China plate and Siberian plate, must be incorrect; 2 The age date show that the earliest magmatic activity began since late-Palaeozoic Permian, which is inconsistent with the previous idea that there were Caledonian and Hercynian active continental margin in the north of North China Craton and in the south Xingkai Massif. 3 the crust and lithosphere were thickened by the subduction and collision of Siberia plate and North China plate during Late Paleozoic. The magma is formed when the crust is heated and melts caused by thickened lithosphere delamination and caused the Asthenosphere upwelling. But only a little basaltic magma erupted, most magma underplate under the bottom of the crust. Thermal energy derived from basaltic magma underplating made the middle and lower crust melt partially and the late Permian-early Triassic granites is formed in large scale.
根据区域构造演化分析,并结合本文及他人高精度同位素年龄,我们对延边花岗岩形成的大地构造环境有了新的认识:1在华北地台北缘并不存在所谓的加里东花岗岩带,因此,建立在此之上的传统的华北地台北缘演化模式及有关西伯利亚板块与华北板块的碰撞拼合的认识也必然是不正确的;2华北地台北缘和兴凯地块南缘不存在加里东期和海西期花岗岩带,表明两地块边缘最早的花岗质岩浆活动始于晚古生代的二叠纪,即不存在传统观点所认为的加里东期或海西期活动陆缘;3晚古生代由于西伯利亚板块与华北板块的俯冲碰撞,致使地壳和岩石圈增厚,导致加厚岩石圈发生拆沉作用,使得软流圈上涌,加热地壳使之熔融形成岩浆,但玄武质岩浆少量喷出地表,大部分底侵于地壳底部,形成下地壳高密度的玄武质底侵层,玄武质岩浆底侵的热能引起中下地壳广泛部分熔融,形成大面积分布的晚二叠世—早三叠世花岗岩。

Accompany with the subduction of Pacific and Indian plates, upper mantle convected more violently, and new upwelling astheosphere replaced and eroded the lithosphere, and resulted in irregular thinning of cloud-like mantle along reticulated or dondroid weak zones. The thinning was dominated by replacement of lithosphere with new upwelling astheosphere, and accompanied possibly by delamination.
在这过程中,特别是伴随太平洋、印度洋板块的俯冲作用,地幔对流加剧,上涌的新生软流体顶蚀置换岩石圈,从而造成了沿早期业已存在的幔内薄弱带网络,出现类以&蘑菇云状&的地幔不规则减薄,这种减薄以新生软流体取代岩石圈为主,并可能伴随一定程度的岩石圈拆沉作用发生。

The results of the study indicate:(1) the stress, strain and velocity fields as well as the uplift rates of the model are consistent essentially with those of the prototype in nature;(2) the major driving force for intraplate tectonic deformation in central-eastern Asia results mainly from the compression of the Indian plate;(3) the existence of the RSBs, such as those of Tarim, Alxa, Ordos and Sichuan basin, is one of the basic origins for the development of large-scale compressional basins and the table-like uplift of the Qinghai-Tibet plateau;(4) The netlike plastic-flow in the lower lithosphere is faster than the displacement in the upper layer, controlling the tectonic stress and deformation fields in the upper crust;(5) the weakness layer distributed discontinuously in the middle crust influences the level of difference between the stress directions in the lower lithosphere and those in the seismogenic layer.
研究结果表明:(1)模型中的应力场、应变场、位移速度场和地表隆升速率,与自然条件下的实际状况基本相符;(2)中东亚板内构造变形的驱动力源主要来自印度板块的推挤作用;(3)塔里木、阿拉善、鄂尔多斯、四川盆地等相对稳定块体的存在是促成大型压性盆地形成和青藏高原平台式隆升的基本原因之一;(4)岩石圈下层的网状塑性流动超前于上层,控制上层的构造应力场和变形场;(5)中部地壳的非连续分布软弱层影响上、下层之间应力方向的差异程度。
