摘　　要：新疆位于亚洲大陆的北部,构造上跨越了古亚洲和特提斯两大构造域,现今主要由中新生代盆地和其间的古生代造山带组成。古生代造山带主要由陆缘岩系和岩浆岩组成,其中夹有洋壳残片和前寒武结晶基底的碎块;洋壳残片从北向南大致分布12条,其中出露较集中的约30多处。这些蛇绿岩,以塔里木盆地为界,北部主要为古亚洲洋的洋壳残片,南部主要为特提斯洋的洋壳残片。在介绍其基本特征的同时,本文侧重报道了近年来新疆区域地质调查的一些成果。Xinjiang is located in the northern of Asia continental block,it involved two tectonics region that is ancient Asia and Tethys tectonic domains. Now it is composed by Mesozoic-Cenozoic basin and Paleozoic era orogenic belt between those basins,Paleozoic orogenic belt mainly composed by epicontinental rock formation and magmatic rocks,include some fragments of oceanic crust and Precambrian crystallize basement. There are 12 oceanic crust fragments distribution from north to south,and concentrate fragments in 30 locations. These ophiolites be detached by Tarim basin,the northern is ancient Asia oceanic crust fragments and the southern is Tethys oceanic crust fragments. This paper introduces those basic characteristics and some latest progress of regional geological survey in Xinjiang.
