| 摘 要： | 新疆东准噶尔地区姜巴斯套组构造上位于卡拉麦里断裂和清水—苏吉泉断裂之间,本文根据该套地层的野外地质特征、岩石学特征及古生物化石特征,讨论其形成时代。同时结合前人对卡拉麦里蛇绿岩研究的资料,以及蛇绿岩被早石炭统姜巴斯套组不整合覆盖,确定该洋盆闭合早于早石炭世,这对探讨东准地区构造演化有重要的科学意义。

| Abstract: | Jiangbasitao Formation of Eastern Junggar in Xinjiang is geologically located between Kalamaili fault and Sujiquan fault. This fossil characteristics of the Ji study on the Kalamaili ophioli paper has studied the field geological features, petrological characteristics, and the angbasitao Formation, investigated its formation age. Combined with the previous tes,considering that it is unconformity covered by Early Carboniferous Jiangbasitao Formation, we conclude that the ocean basin closed before Early Carboniferous |
