The evolution process under the control of the multigeodynamic force system (including the boundary forces of Eurasia-Pacific-Indian three massive plates around Nansha block, effects of the deep mantle, relative soft layer-sliding planes within Nansha lithosphere block and the earth's rotational inertial force) can be briefly divided four stages: the late Cretaceous to the early Eocene stage of uprilfing-erosion and shear-extension caused by the oceanwards-eastwards withdrew of Pacific subduction zone and the delamination of proto-subducted slab after the stage of pre-Cretaceous pre-rifting active continentoceanic plate margin. In this stage, the Nansha transcrustal layering-block started to move southeastwards on the Nansha transcrustal layer-sliding plane, meanwhile, the Andu-Bisheng and Liyue-Banyue basement layering-block slid on their upper-crust layer-sliding planes, and Xibu accretion zone was formed. Successively, it entered the stage of the mid-Eocene to early Oligocene, when NW-SE sea-floor spreading occurred in the southwest subbasin owing to the slip-line field initiated by the collision between the Indian and Eurasian plates, Zengmu foreland-basin started to develop in the same time. And in the stage of late Oligocene to early Miocene, near NS simple-shear extension and sea-floor spreading in the central subbasin of eastern South China Sea resulted from the south-southeastwards drawing-force of the mantle-flow. The crustal layering-blocks and the Miri accretion zone formed also in this stage.

南沙岩石圈新生代微板块及板内层块构造的动力演化过程，在多元动力等因素(如块体之外的欧-太-印三大板块运动边界力和地幔深部活动因素、块体内部软弱层滑面以及地球自转变化)控制下，大致经历了4个阶段的演化：从前晚白垩世的裂前活动陆-洋板块边缘阶段因太平洋俯冲带向东跃迁、原向NNW俯冲消亡的板片的拆沉、幔隆而进入晚白垩世-早始新世的隆升剥蚀、剪切伸展演化阶段，南沙超壳层块顺超壳层滑面祥东南运移、安渡-毕生与礼乐-半月基底层块沿上壳层滑面拆离，西布增生带形成；继而先后在中始新世-早渐新世期间受印-欧板块碰撞滑线场、地球自转加速影响出现西南海盆NW-SE向海底扩张和曾母前陆盆地的发育，和晚渐新世-早中新世期间南—东南向地幔流牵引造成的中央次海盆近NS向单剪伸展与海底扩张、壳体层块向南差异滑移、米里增生带形成；中中新世以来，印度-澳洲板块快速向北俯冲，构成今日南海格局。

The low temperature and the short time are benefit to forming and reserve the ultrahigh\|pressure metamorphic rocks.

MDJ台下660km间断面的复杂性体现了俯冲带物质在660km间断面上的堆积，而HIA下660km间断面的存在情况，则表明俯冲带的影响已经相当地弱了。

The results are shown as below.1 Tectono-thermal evolution: The history of the Songliao basin is divides into four stages, high-temperature doming and extension, high-temperature rifting, low-temperature depression, and low-temperature shrinkage. Numerical simulation of mechanical process shows that the basin appeared in the early- to late- Jurassic as a result of rapid low-angle subduction of the Pacific plate towards the northwest, of movement of the Siberian block towards the southeast, of many other influences such as internal thermal stress in the mantle, gravitational force, stress of phase transition, etc. Both the Pacific plate and the Siberian block slowed down in the early Cretaceous, and almost stopped in the middle Cretaceous with the rapid decrease of abnormal heat in the mantle below.

盆地构造热演化力源机制数值模拟研究表明：早、中侏罗世至晚侏罗世晚期，盆地演化主要是太平洋块体向北西方向以低角度快速俯冲和西伯利亚块体向东南俯冲共同作用的结果，同时也与地幔内部热力、重力、相变力以及地球自转及公转速度变化效应和上覆块体绝对运动的作用有关；早白垩世早期至早白垩世中期，来自东部太平洋块体俯冲作用的减弱，而这一时期影响盆地演化的主要力源是地幔内部热力、重力、相变力以及地球自转及公转速度变化效应和来自西伯利亚块体俯冲作用；进入早白垩世晚期至晚白垩世早期，由于双重俯冲带中西侧俯冲作用带基本停止活动，而本区地幔热能的快速衰减则控制盆地的构造热演化；晚白垩世晚期以后，太平洋块体活动加强和地幔热运动是影响盆地演化的主要动力。

The orogenic strata have following characteristics: During the subduction and intracontinental orogeny, the strata experienced dramatic tectonic migration and mixing, resulting in various tectonic features. A short sequence usually composed of tectonic slices of various origins, times, deformations and metamorphisms, and scales. The original sequence was badly destroyed. The extant fragments of orogenic belt usually took form as melanges, especially the accretion complex wedge generated in subduction zone, which is contrary to the Law of Superposition. The original location of the accretion is also contradicted with the Law of Original Horizonality, because the accretion is oblique with high degree. Marine rocks, volcanic rocks of continental margin and metamorphic rocks were well-developed in the orogenic belt, especially ultra-basic, basic rocks were wide spread and were intensely metamorphosed, accompanied by metamorphic slices returned from hundred kilometers underground with ultra-high pressure and magma movements during syn-orogeny and post-orogeny, thus formed the colorful landscapes.

subduction zone：俯冲带

现在看来,似乎任何处在俯冲带(subduction zone),即一个地质构造板块向另一个地质构造板块下放推进的地方,都有可能经历具有灾难性的9级地震. 以前,人们认为根据正在相撞的两个板块的速度、它们的硬度和年龄,不同俯冲带造成9级地震的风险会更高或更低.
