The study on this area may provide good information about the late evolutionary history and closing age of the Tibet-Tethys remnant sea. In this work, a great number of microfossils have been found and identified. Study on the microfossils (especially planktonic foraminifera) indicates:(1) the youngest marine bed in Tibet is represented by the top of the Sandstone-shale Member of the Zhepure Formation that occurs in the Zongpuxi Section of the Gamba area, and is of the early Late Eocene age. The age stands for the final closing of the Tibet-Tethys;(2) The age of the youngest marine bed in Gamba is correlative with, or more or less younger than that of the Tingri region. Both are referred to early Priabonian.

对岗巴－定日地区内始新世地层剖面作了极为详细的研究工作，发现并鉴定了数量较为丰富的微体化石，在此基础上对西藏特提斯晚期沉积环境的演变进行了较为详细的分析，认为岗巴地区遮普惹组砂页岩段的时代与定日遮普惹组砂页岩段的时代相同或略晚于后者，两者基本上属同期异相沉积，含相同的浮游有孔虫Morozovella spinulosa-Acarinina bullbrooki组合；藏南最高海相层－遮普惹组砂页岩段顶部的时代应为晚始新世Priabonian早期，它代表着西藏－特提斯海在藏南最终消亡的时间。

The Changning-Menglian belt located in western Yunnan of the Sanjiang fold belt in the Himalayan tectonic region of the Tethys is one of the important areas of studing and resolving many significant geological problems, like the nature、scale、 geological evolution、and ore-forming process of the paleo-Tethys and the boundary between Gondwana and Laurasia、etc., It has been always drawn close attention of geologists.

昌宁-孟连带位于特提斯喜玛拉雅构造域三江褶皱带，是研究和解决古特提斯性质、规模及地质演化、成矿作用及冈瓦纳与劳亚古陆分界等重大地质问题的重要地区之一，历来为地质学家所关注和研究。故滇西古特提斯昌宁-孟连带沉积地质研究对解决上述问题有着十分重要的意义。

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。

Results show that the Spiti shale in Zanskar terminated 15Ma later than that in southern Tibet, while the lowermost Cretaceous quartz sandstone in Zanskar appeared 18Ma later than that in southern Tibet. The age of volcanic sandstone in southern Tibet is very poorly time constraint and their deposition occurred somewhere within Berriasian～early Albian. In Thakkhola, the Chukh Group volcanic sandstone are of late Hauterivian-early Albian age (duration about 20Ma), while in Zanskar, the volcanic sandstones facies only appeared in Albian (duration of less than 10Ma). Therefore, it can be concluded that the onsets of both quartz sandstone and volcanic sandstone occurred earlier in eastern Tethys Himalayas than in western Tethys Himalayas .

侏罗纪末～白垩纪初印度大陆的北缘同时期存在大陆向上挠曲，导致陆源碎屑输入量的快速增加，石英砂岩广泛存在；早白垩世火山岩屑砂岩对应着的印度大陆北缘地层侵蚀加深，使得较深部的深成火山岩暴露并遭受侵蚀；石英砂岩和早白垩世岩屑砂岩所代表的印度大陆剥露时间在空间上的&东早西晚&，说明构造运动首先是从特提斯喜马拉雅的东部开始（大印度与澳大利亚的彻底分离），然后逐渐波及西部的，东西时间差为15～20Ma；由于地壳均衡作用，大陆分离后原先地壳挠曲转变为地壳下沉，发生强烈的构造沉降，故Albian之后沉积一套深水环境下的海绿石、磷酸盐和黑色页岩沉积。

The Centr al Tethys Region lies in Hoh Xil-Bayan Har. Since Late Palaeozoic, the back-ar c bathyal basin continued to break and spread. The typical oceanic crust was event ually formed in Carboniferous and Permian. The Ocean during that period is named the Paleo-Tethys, of which the remnant is the Third and the Fourth suture zone s.

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。
