  1. 以雅鲁藏布江带为主洋盆带的特提斯洋,从三叠纪晚期开始消减,经历了印支、燕山、喜马拉雅3个阶段脉动式板块汇聚造山过程。

    The Tethyan Ocean with the Yarlung Zangbo belt as the main ocean basin belt began to be sub-ducted in the Late Triassic and experienced a process of pulsatory plate convergence orogeny including the Indosinian , Yanshanian and Himalayan stages .

  2. 我们推测,与印度-亚洲碰撞和欧亚-太平洋板块汇聚相关联的中国东部拉张盆地在始新世时期的持续发展为落叶阔叶植被的生存和发展提供了有利的场所和充分的水汽。

    Influenced by the India-Asia plate collision and the Pacific-Asia plate convergence , the extensional basins in East China developed significantly during the Paleogene , and provided favorable spaces and adequate moisture for the continuous development of broadleaf trees in East China .

  3. 名义上无水矿物(NAMs)的结构水研究是认识超高压变质作用(UHPM)过程中流体活动规律的重要手段,并对板块汇聚边缘大陆动力学及水的深部地球循环有重要意义。

    The research of structural water in nominally anhydrous minerals ( NAMs ) is significant for understand of the fluid flow activity in ultra-high pressure metamorphism , the geodynamics in convergent continental margins and the water recycling in mantle .

  4. 苏鲁超高压榴辉岩中的钛成矿作用:大陆板块汇聚边界的成矿作用

    Titanium Mineralization in Sulu Ultrahigh-Pressure Eclogites : Mineralization at the Convergent Boundary between North China Plate and Yangtze Plate

  5. 板块汇聚带的造山和重力垮塌作用及其力学成因:以雅鲁藏布江-喜马拉雅山汇聚带为例

    Orogeny and gravitational collapse along the convergent plate boundary and their mechanical origin : a case study on the Yarlung Tsangpo-Himalaya belt

  6. 在栾川地区板块汇聚方向为31°,汇聚方向与板块边界的夹角为82°,显示出秦岭造山带与华北板块南缘的碰撞和拼合具有典型的斜向汇聚特征。

    This shows that the collision and convergence between the Qinling orogenic belt and the southern margin of the North China plate have the typical features of oblique convergence .

  7. 地壳的两大组成部分&洋壳和陆壳,由于在物质成分上的巨大差异,致使在板块汇聚边界的俯冲消减作用中,二者呈现截然不同的地球动力学特征。

    During the subduction processes at the plate convergent boundary , the continental crust and oceanic crust , due to their remarkable differences in composition , show striking different dynamic characters .

  8. 这种特征可能不仅和海洋与大陆板块汇聚边界的岛弧海沟上的基本应力状态有关,而且与自转速率不均匀产生的附加应力状态有关。

    These correlations depend not only on the state of the basic stress field in the island arc-trench but also on the additional stress field caused by the variation of rotation velocity of the earth .

  9. 新疆北部福海地区处于西伯利亚与哈萨克斯坦两大古板块的汇聚带,构造活动强烈,属岛弧及弧后盆地构造环境。

    The Fuhai area of north Xinjiang is situated in the convergent zone between Siberia Plate and Kazakstan Plate . This area was in an island arc and retroarc basin environment so that its structure activity is violent .

  10. 板块剪式汇聚加地体拼贴&中特提斯消亡的新模式

    Shear convergence of plates and suturing of terranes : a new model for the comsumption of the Meso Tethys

  11. 中国大陆及邻近陆域海域是晚古生代以来由多个较小的板块或地块汇聚形成的。

    The continent of China and its adjacent land and sea areas were formed by convergence of a number of small plates and blocks since the Late Paleozoic .

  12. 查干诺尔铜矿床产在西伯利亚板块和华北板块汇聚带附近,华力西晚期构造岩浆带内。

    The Chaganuoer copper deposit is located near the assembly belt of Siberian plate and North China plate , and within the tectonic-magma belt of Late Variscan .

  13. 逆冲推覆的区域应力来自地体向东的碰撞拼接,是印度板块与扬子板块汇聚的重要构造事件。

    The regional stress of the thrust nappe is resulted from the eastward collision conjunction of the terrain , which is the important structural event in the convergence of the Indian Plate and the Yangzi Plate .

  14. 简单剪切发生在晚白垩世&早始新世,其动力与太平洋板块俯冲带的后撤、太平洋板块与欧亚板块之间汇聚速率的降低、以及先存北倾缝合带等密切相关。

    The simple shear extension mainly occurred in Late Cretaceous-Early Paleogene , related to slab roll back of Pacific plate , decreasing Paleogene Pacific-Eurasia convergence rate and possible preexisting suture zone .
