    The first disintegration of Altgn Tagh rock group and the characteristics of Altgn Tagh complexes

    • 摘要: 阿尔金构造带因其所处青藏高原北缘构造转换之位置及其地球动力学研究意义成为地学研究的热点地区,阿尔金群是该构造带的结晶基底。对它的研究以往主要集中于路线上,作者通过1:25万区调填图,对原阿尔金群的岩石组成、构造变形等作了系统调查后,认为:原阿尔金群是由前寒武纪不同时代中酸性变质古侵入体、变质表壳岩与含榴辉岩、石榴石二辉橄榄岩的高压超高压变质外来岩片等构成的构造杂岩,即阿尔金杂岩,真正的阿尔金岩群仅是其中的变质表壳岩类。阿尔金杂岩中不同地质体和不同岩类的变形及其相互关系复杂,它是经历了前寒武纪基底构造奠基—早古生代主造山期活化形成—晚古生代以来陆内变形多次改造而铸就的大型复合型构造带
      Abstract: Altgn Tagh structure zone has been studied by many geologist for the significance of geodynamic and its peculiar location-structure transformation in the north margin of Qing-hai-Tibet plateau.The Altgn Tagh rock group is the Altgn Tagh structure zone's crystalline basement.And studying of it was on a few geological routes in the past survies.Based on regional geology mapping of 1:250000 scale,the author analyzed systematically the rock constitution and deformation of structure of the preliminary Altgn Tagh,and found out that the preliminary Altgn Tagh rock group is made up of neutral-acidic the old metamorphic intrusive body,superacrustals and eclogite and garnetiher zolite-bearing high-ultra high pressuremet amorphic rocks from out side in different periods of Pre-Cam brian,called the Altgn Tagh complexes.The real Altgn Tagh rock group is only metamorphic superacrustals.The deformation and all kinds of block and rocks and their relationship are complex.The Altgn Tagh complexes,which had undergone Pre-Cambrian the formation of crystalline basementre-building in main orogenic period of early Palaeozoic-defo rmations within mainland in late Palaezoic,is alarge complex structure zone.
