查询词典 mantle

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。
