查询词典 ocean basin

1:250000 geological mapping has further revealed the mysteries of the tectonics of the Qinghai-Tibet Plateau. The Altun Mountains are not of the Tarim massif, but a part of the Kunlun-Qilian-Qinling orogenic system; the Altun fault is a large transform fault; the Muztag-Maqên suture zone and Jinshajiang suture zone are both Variscan ones; the Songpan-Garzê area in the Triassic was a huge turbidite basin on the southern margin of Laurasia; the Gangdise belt underwent the important Indosinian orogenic movement; an ocean basin that persisted from the Paleozoic to Triassic did not exist, i.e. the so-called Paleo-Tethys or permanent Tethys was not in existence in the Qinghai-Tibet Plateau. In the Paleozoic, most parts of China, including the Sino-Korean, Yangtze and Tarim massifs and the Qinghai-Tibet Plateau, were located in south of the main ocean basin—the Central Asian-Mongolian sea way—of the Paleo-Asia ocean, belonging to the northern margin of Gondwana. The Yarlung Zangbo and Bangong -Nujiang belts were twins in the Tethyan Ocean, which began to develop into two ocean rift belts in the Triassic. The Tethyan Ocean with the Yarlung Zangbo belt as the main ocean basin belt began to be subducted in the Late Triassic and experienced a process of pulsatory plate convergence orogeny including the Indosinian, Yanshanian and Himalayan stages.

1：25万地质填图进一步揭开了青藏高原地区大地构造的奥秘：阿尔金山是昆仑，祁连-秦岭造山系的一部分；阿尔金断裂确是一条大型转换断层；木孜塔格-玛沁缝合带和金沙江缝合带均是华力西缝合带；松潘甘孜三叠系沉积盆地是劳亚大陆南部边缘的浊积岩盆地；冈底斯带曾经历了重要的印支造山运动；不存在从古生代延续到三叠纪的大洋盆地，即不存在所谓古特提斯或永久特提斯；古生代时期，在青藏高原地区亦不存在具古生物，古地理分隔意义的大洋盆地，当时，包括中朝，扬子，塔里木以及青藏高原地区在内的中国大部分均位于古亚洲洋主洋盆——中亚-蒙古带之南，属冈瓦纳大陆结构复杂的北部边缘；雅鲁藏布江和班公湖-怒江带是特提斯洋中的孪生姊妹，它们均是从三叠纪起就发展成大洋裂谷带的；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。

This thesis studies each structural layer's feature:(1) structural layer of basement:it is a Paleozoic folded basement,whose tectonic deformation and magma intrusion is fiercely,and it is affected by the early Hercynian tectonic movement and related to the underthrust and closure (C1) of Zhungaer ocean basin and the areal pressing of continents (C2-3);(2) structural layer of Permian:due to the regional extending and fault depression role in mid-Hercynian,it occurred to the combinations of structure and magma in Santanghu basin and it's periphery area,such as A-granite's stock,batholiths and diabase's dike.

The age of MORB-type metabasic volcanic rocks is(1462± 28) Ma using the SHRIMP zircon U-Pb method.The presence of MORB and IAT assemblages suggests the existence of an ocean basin in Yunkai area,Guangxi,southwestern South China Block during Grenvillian.They probably defined as a part of archipelagic ocean system before South China has formed unified Rodinia during the Grenvillian orogeny.Cathaysia block and Yangtze block have experienced continent-continent collision orogenics behind this ocean basin subducted,and have formed unified Rodinia.

MORB和 IAT组合的出现说明位于华南板块西南端的广西云开地区在 Grenville期可能存在过洋盆，它们很可能代表了 Grenville期造山作用形成统一的 Rodinia超级大陆以前的一个&多岛洋盆&系统，华夏古陆和扬子板块可能在该古洋盆于新元古代早期发生的全球性 Grenville期造山运动而发生消减消失后才开始碰撞和造山，形成统一的 Rodinia超级大陆。

According to the geochemical data, the formation of mantle peridotite might be: during the spreading of ocean floor, the MOR mantle underwent variable degrees of partial melting and formed the depleted mantle peridotite with podiform chromitite; during the spreading of ocean basin, intra-ocean subduction happened, REE and LILE rich fluids containing water derived from the subduction slab migrated upwards and metasomatism happened to peridotite relic.

康金拉矿区的地幔橄榄岩的地球化学特征反映了其形成过程的复杂性，表现为：洋底扩张期间，扩张脊下的MOR型地幔的经历了不同程度的部分熔融，形成了亏损地幔橄榄岩，该地幔橄榄岩中赋存了来自深部的豆荚状铬铁矿。

This age stands for the formation time of the ocean basin of Xiugugabu-Daba Tethys, and is very close to that of the middle part of the Yarlung-Zangbo suture zone (126±1.5 Ma). This outcome provides a well chronologic condition for discussing the palaeotectonic framework and the evolution of the Tethys basin in the study area. In addition, the forma...

该年龄代表了休古嘎布-达巴特提斯洋盆的形成时代，与雅鲁藏布江缝合带中段洋盆形成时代(126±1.5Ma)相当，此结果对于确定研究区特提斯洋盆的古构造格局及其发育演化过程等提供了重要的年代学制约。

Based on analysises of characteristics of regional deformation and metamorphism as well as Carboniferous and Permian relict basins, think Qinling-Dabie orogenic belt might have undergone following Basin-mountain transformational process : the ocean basin developed in Silurian-early Paleozoic; ocean basin subduction began in Ordovician; Silurian-early Devonian continent-continent collision happened and the ocean basin disappeared; Carboniferous- Permian, with the strike-slip and pull-apart along the Shangdan fault, a series of small faulted basins formed on the north Qinling mountainous region composing of Pre-Carboniferous metamorphic stratum.

在解析区域变形变质特征，岩浆侵位的构造演化和北秦岭区石炭—二叠纪残余盆地分析基础上，认为秦岭—大别造山带现今的残余的加里东造山带，可能经历了震旦纪—早古生代洋盆发育，奥陶纪洋盆俯冲，志留纪—早泥盆世碰撞造山，洋盆消失，石炭—二叠纪沿商丹带走滑拉分断陷形成上叠于北秦岭加里东造山带之上的石炭—二叠纪沉积盆地的盆山转换过程。
