| 摘 要： | 通过对莫托沟─古尔图蛇绿岩特征的研究，认为该区蛇绿岩尽管受到强烈的多期构造肢解，但根据岩石类型仍能恢复蛇绿岩的原始层序，代表了早石炭世－中石炭世强烈拉张所形成的海盆壳－幔型建造残块，是古洋壳最后闭合的一部分。因此，笔者认为：巴音沟─莫托沟─古尔图蛇绿岩套，是哈萨克斯坦板块与塔里木板块多次聚合俯冲所形成的，是划分两大板块界线的重要依据之一。

| Abstract: | The study of the ophiolites in Motogou -Gurt shows that the ophiolites have gone through intense multiphasal structural dismantling.The primary sequence of the ophiolites can be reconstructed by the rock types.It represents the remains of oceanic basin crust-mantle type formation formed by intense extension of early Carboniferous-middle Carboniferous,as a part of the final closure of palaeo-oceanic crust.So the author believes that Bayingou Motogou-Gurt ophiloite suit is formed by multiphasal convergence and subduction of Kazakstan plate and Tarim plate,and is an important basis for the boundary division of two plates. |
