| 摘 要： | 红石山蛇绿混杂岩产出于塔里木板块北缘红石山深大断裂带中。其物质组成反映出该杂岩形成于小洋盆环境。时代为早石炭世晚期，后经历了至少3期构造变形变质作用的叠加与改造。于二叠纪晚期运移至地表。作者进一步论述了红石山蛇绿岩的组成及变形变质特征，为研究北山北带提供了最新资料。

| Abstract: | The ophiolite migmatitic complex is in Hongshishan deep huge rift of the north margin of Tarim slab. It formed in the environment of the small ocean basin for its constitution of material in the later Early Carboniferous. And by reform of at least three stage structural deformation metamorphism ,it returned to terrene by shearing at the Late Permian. The authors discuss constitution and deformation metamorphic characteristics in Hongshishan region, and provide the recently material for the researching of the north belt of Beishan. |
