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 regions which good quality jadeites should be determined by the four constraints as fellows: 1. In the subduction or collision zone; 2. In the ultrabasic rock bodies especia1ly in duniue bodies; 3. HP~UHP metamorphism zone; 4. Long duration deformation and metamorphism after rock forming.

优质翡翠的成矿预测与找矿靶区的确定应是符合以下四个条件的地区,即:a俯冲带或碰撞带内;b超基性岩体主要是纯榄橄岩体内;c高压与超高压区;d后期发生过长期的动力变质变形作用。

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。

It is generally thought that the dynamic subsidence is associated with supercontinental assembly and dispersal and subducting slabs.

动力地形一般认为具有两种成因,一种为与超大陆集聚和分散有关的动力地形,另一种为与大洋板片俯冲有关的动力地形。

In the new model the tectonic driving force is not the mantle convection, but the relative movement of horizontal shear between the continental lithosphere slab due to A-type subduction characterized by spreading and separating and the asthenosphere.

新模式不是以地幔对流运动,而是以扩张分离A型俯冲的大陆岩石圈板片与软流圈之间的水平剪切相对运动机制作为它的躯动力。
