被动大陆边缘 meaning in Chinese
passive continental margin
Examples
- The relationships between the accumulation of gas hydrates and the typical diapirs in passive continental margin are summarized in primary in this paper which suggest that the factors in passive continental margin including the thick sediment layers , plastic substance , high pressure fluid , outboard volcanic activities and the process of stretch - rupture provide favorable conditions for the formation of the diapirs which can form advantageous environment for gas hydrates coming into being
初步总结了被动大陆边缘中典型底辟构造与天然气水合物的成矿关系，认为被动陆缘内巨厚沉积层、塑性物质与高压流体、陆缘外侧的火山活动及张裂作用，为底辟构造发育提供了条件，形成了水合物成矿的有利空间。 - The geochemical examination of the sandstones and mudstones from the xikang group has led us to conclude that the debris are derived mostly from the surficial rocks and their overlying deposits on the xikang - yunnan ancient land , and tectonic settings display the transition from the passive continental margin to active continental margin and finally to archipelago
通过对西康群砂、泥岩地球化学组成特征研究，认为其物源来自康滇古陆表壳岩及其上覆的盖层沉积，大地构造属性为被动大陆边缘到活动大陆边缘再到多岛弧的转化。 - The tectonic subsidence curves on the southeastern margin of the yangtze plate are drawn out using of backstripping method for the basin formation and evolution . the basins located in the southern margin of the yangtze plate , in the basin dynamic computer simulation , is explored and constituted to be a typical foreland basin which is of not rather high mountain and thermal situation to be lower in this older orogeny belt
在沉积盆地分析方面，基本查明扬子板块东南边缘早古生代被动大陆边缘沉积特征及沉积构造演化，同时运用反剥法技术对扬子板块东南大陆边缘沉积盆地形成，演化的构造沉降动力学进行探讨，运用计算机模拟方法，定量动力沉积学对扬子东南边缘奥陶纪到志留纪前陆地进行计算机模拟分析，探索并建立这个古老造山带前陆盆定量参数和动态定量模拟。 - On the basis of analysis on the characteristics of structural evolution , the growth of the source rocks is analyzed . in the period of mesozoic - palaeozoic , caledonian events and the evolution of hercynian - early indo - chinese cycle are experienced in two - phase marine passive continental margin and craton basin in the lower and middle yangtze region , by which stable enormous thick mesozoic - palaeozoic deposites are induced , six sets of source rocks are produced , it has a strong capacity of hydrocarbon generation
摘要通过构造演化特征分析了海相烃源岩的发育，中、下扬子区中古生代经历了加里东和海西早印支旋回两个阶段的海相被动大陆边缘和克拉通盆地演化，形成了岩性稳定的巨厚中古生界，发育了6套烃源岩，具有较强的生烃能力。 - Abstract : in the light of sequence stratigraphic research work on permain coal - accumulating basins in south china and jurassic ordos coal - accumulating basin in north china , the sequence stratigraphic model and coal - accumulating model of passive continental margin and continental down warping basin were established , the comparison between both settings was also briefly conducted
文摘:运用层序地层学原理，对华南二叠纪含煤盆地和侏罗纪鄂尔多斯含煤盆地进行研究，建立了被动大陆边缘盆地和陆相坳陷盆地的地层层序沉积模式和层序聚煤模式，并对两者聚煤作用作了简要对比。
