| 摘 要： | 新疆东准噶尔卡拉麦里蛇绿岩带是一条重要的蛇绿岩带,其所代表的古大洋是中亚古生代构造框架中一个非常重要的构造单元。对于该带归属何古板块之间的缝合带存在着截然不同的认识,对卡拉麦里蛇绿岩前身洋盆俯冲闭合年限也存在多种观点。根据对前人研究资料的综合,简要地论述了该断裂带是准噶尔洋俯冲消亡的遗迹,其闭合年限在350Ma左右。

| 关 键 词： | 卡拉麦里 蛇绿岩 古板块边界 准噶尔洋俯冲带 |

| Abstract: | Kalamaili ophiolite in east Junggar, Xinjiang is an important tectonic unit in the central Asia Paleozoic tectonic framework. There are some arguments whether the belt is a suture zone between ancient plates or not, and time of the closure of the paleoocean basin that kalamaili ophiolite represented. Based on the former research, Kalamaili fault belt is a subduction zone of Junggar ocean which is around 350Ma. |
