| 摘 要： | 中亚地区分布着数十条不同时代和不同性南的蛇绿岩带，这些形成于早古生代或新元古代的蛇绿岩带由于受后期构造变动的强破坏，只在极少数地点保存良好。尽管出露分散，确定其时代和性质有一定困难，但其仍具极其重要的构造单元划分、对比和连接意义。在对比和讨论蛇绿岩带的连接时，应以微体化石给出信息为主，同时参考蛇岩下部组分的同位素年代学数据。讨论了新疆东北部邻区和西部邻区蛇绿岩带的时代和性质，以及这些蛇绿岩带的对此

| Abstract: | Tens ophiolitic belts with different ages and characteristics distribute in Central Asia.Only a few of them are well preserved because of strong destruction of tectonic events.Those ophillitic belts still have a significance of primary importance in division and correlation of tectonic units enen though determining their age and characteristics are difficult and their outcrops are scattered.Microfossil and isotopic age of low component part of ophiolite should be important basis for studying link and correlation of ophillitic belts.This paper is going to discuss the ages and characteristics of ophiolitic belts in Northeastern Xinjiang and its northern adjacent area and Northwester Xinjiang and its western adjacent agea.And discuss the links and correlation of the opliolitic belts and links of tectonic belts between Xnjiang and adjacent area. |
