| 摘 要： | 利用1∶25万区域地质调查工作所获新太古—古元古代变泥质岩类岩石地球化学资料,以变泥质岩与同时代火山岩物源成因关系,探讨阿尔金和东昆仑造山带古老基底原始古陆系统的隶属问题.结果得出:新太古—古元古代时,阿尔金和东昆仑两造山带基底属同一古陆系统的不同部分.在此基础上,结合前人研究成果,初步提出塔里木、柴达木、阿尔金及东昆仑应为同一古陆体系或古陆块.

| Abstract: | The paper is discussed on the attribution of ancient basement between Altyn orogenic belt and East Kunlun orogenic belt from the relation meta-pelitic rock with contemporary volcanic rocks, using the petrological geochemistry data of metapelitic rock from Neoarchean to Paleoproterozoic which gained from the 1:250000 regional geological surveys.Conclusionly, Altyn orogenic belt and East Kunlun orogenic belt belong to the different parts of same ancient continent |
