查询词典 tectonics

Then on the basis of study results about regional geology, ophiolite,structure,and seismic depth-sounding in the Qinghai-Tibet plateau and its adjacent areas, this paper promotes a new model to interpret tectonics.This new model thinks that in this large area there was not simple B-type subduction which is accompanied with ocean-floor spreading at mid-ocean ridges to form ocean basins appearing as new oceans and new ocean plates,but intercontinental seas due to ocean-floor spreading,obduction of ophiolite tectonic slice as oceanic crust slabs and complex A-type subduction of continental lithosphere slabs.

而后又以青藏高原及邻区为例，根据区域地质、蛇绿岩和地质构造研究的成果，特别是地震测深研究的成果，详细地论证了本区不存在有大洋中脊扩张成为大洋盆地的新大洋和大洋板块简单的B型俯冲模式，但存在有海底扩张的陆间海和海洋地壳板片的仰冲以及大陆岩石圈板片复杂的A型俯冲新模式。

In view of an analysis from lithospheric geoid, horizontal stress and existing seismic tomographic data and so on, they show that Chinese mainland and adjacent area is controlled by mantle dynamics of interaction, mutual influence and constraint by western Pacific ocean plate, Indian plate and circum-Siberian arc tectonics that formed after Paleo-Asian ocean closed, which consist of three tectonic areas, with on the base of the Tethyan tectonic realm. Overall tectonic framework of the Chinese mainland is outwards obduction along main tectonic borders within shallow crust and inwards subduction and convergence within deep lithospheric mantle from south-western, south-eastern and northern parts, respectively.

基于岩石圈大地水准面异常、水平应力场和地震层析等地球物理资料综合分析可知，中国大陆及其毗邻地区在特提斯构造基础上，处于西太平洋板块、印度板块和古亚洲洋及其闭合之后环西伯利亚弧形等三大全球构造体系域相互作用、相互影响和相互制约的地幔动力学控制之下，总体大地构造格局是浅部地壳分别沿主要构造边界向外仰冲，深部岩石圈地幔则从西南、东南和北部向中国大陆俯冲会聚，使之整体处于地幔会聚挤压的大地构造背景。
