Recent collections from six sections , lanongla area , tethyan himalaya allow the establishment of four ，在世界其他产地都出现于早白垩世地层，并研究识别出

The studies on the volcanic rocks from these two areas provide new evidences for understanding the paleo - tethyan evolution 这两个地区的火山岩研究为了解古特提斯的演化提供了新的证据。

The changning - menglian belt , located the drape belt of three river in structure territory of tethyan - himalayan , is the one of most pivotal areas which is redounded to research and resolve the problem 昌宁?孟连构造带位于特提斯?喜马拉雅构造域三江褶皱带，是研究和解决该问题的最为关键的地区之一(刘本培等， 1993 ；崔春龙， 1999 ) 。

The main continent rift developed in mid - late proterozoic ; the paleo - asian tectonic dynamic system played an important role in the paleozoic period ; the combination of tethys - paleopacific tectonic dynamic system influenced the basin in mesozoic . during that period , the tethyan dynamic system affected the basin in the early stage ( t ) while paleo - pacific dynamic system affected it in the latter stage ( js - k ) ; the new tethyan - circum pacific tectonic dynamic system dominated in cenozoic period 中新元古代为大陆裂谷集中发育阶段；古生代主要受控于古亚洲构造动力学体系；中生代主要受控于中特提斯?古太平洋构造动力体系的联合作用和影响，其中早期( t )主要受特提斯动力体系影响，晚期( j _ 3 - k )主要受古太平洋动力体系影响；新生代主要受控于新特提斯?今太平洋构造动力体系的联合作用和影响。

We deduce that it is a relic old crust that was brought upwards during the formation of neo - tethyan ophiolite . the step heating 40ar - ' 9ar spectra show that during 100ma , luobusha ophiolite suffered intensely alternation , which affected distinctly the k - ar system ; during 771ma some basalt formed in the country rock of xiubugabu ophiolite ; during 55ma , the pillow basalt of rikangba ophiolite affected by a strong thermal event ; all the variety of ages illustrates possible impacts of the subduction - collision between india and eurasia . through dissecting mainly the gabbro of luobusa ophiolite and studying the 40ar / 39ar ~ ( 40 ) ar ~ ( 39 ) ar阶段升温年龄图谱显示， 100ma左右罗布莎岩体经历了较强的后期蚀变作用，对其k ? ar体系造成明显影响； 77 1ma休古嘎布岩体围岩中形成玄武质火山集块岩； 55ma日康巴岩体岩石枕状玄武岩受到较强热事件影响；这些~ ( 40 ) ar - ~ ( 39 ) ar年龄上的变化显示了印度板块与欧亚板块俯冲?碰撞对该区的强烈影响。

There existed several strong reformation of late - yanshan movement and himalaya movement the generation , development , disappearance and reformation are tightly related to tarim block , tianshan belt and tethyan tectonic zone , especially tianshan belt , which makes the great difference between present and original basin 该盆地形成后经历了燕山晚期和喜山期构造运动的多期强烈改造；其产生、发展和消亡以及改造与塔里木地块、天山构造带、特提斯构造域的演化息息相关。其中尤以天山构造带的活动影响最大，从而造就盆地今古面貌差异巨大。

Since twenty years , with the information accumulation , geologists had already cognizant that the transformation of the asia - australia - pacific ocean area during entire virtually is a process of disorganization of gawana landmass and hyperplasia of asia continent . the most complex and important terra segment in the area is the location which links up the eastern part of tethyan and pacific ocean 近二十年来，随着资料的积累，地质学家已经认识到，亚洲?澳洲?太平洋地区在整个显生宙期间的变化实质上是一个冈瓦纳大陆解体和亚洲大陆增生的过程(黄汲清等， 1987 ；殷鸿福等， 1988 ；钟大赉等， 1993 ) ，其中最为复杂和重要的地段就是特提斯东段与太平洋的衔接处。

The research base on the theories of plate tectonics , use the method that oil and gas basin is analyzed integrally , dynamically and comprehensively , and obey the principle that intersection , superposition and compound of the three tectonic domains ( the paleo - asian , the tethyan and the circum - pacific ) control and influence the formation and development of ordos basin in different tectonic stages 本文以板块构造理论为基础；以含油气盆地整体、动态、综合分析研究为原则；以古亚洲、特提斯、滨太平洋三大构造域交切、叠合和复合，控制和影响着鄂尔多斯盆地在不同构造演化阶段的形成和发育为指导思想。
