摘　　要：阿尔金断裂是中国西北一条巨型的NEE断裂构造,也是青藏高原的西北边界,它在青藏高原的隆升及中国大陆动力学演化方面有着及其重要的地位,一直成为国内外地学界研究的热点.断裂活动的时间、方式、速度及规模等是阿尔金断裂问题争论的焦点.针对目前国内外研究现状,结合柴达木盆地一些实际资料,认为阿尔金断裂带的活动具有多期次性,而至少在中新世时期开始阿尔金总体呈左行走滑的趋势;阿尔金断裂带对柴达木盆地与塔里木盆地的沉积构造演化起着重要的作用,从而对西部大陆构造格架及两侧盆地油气运聚具有重要的控制意义.Aerjin Fault is a great fault in the northwestern China which stretches in NEE direction, and it is the northwestern boundary of Qinghai Xizang Plateau. The fault plays an important role in the uplift of Qinghai Xizang Plateau and the dynamic evolution of China continent mainland. It has been a hot point of the study at home and abroad in geoscience. The times, form, velocity and scale of Aerjin Fault movement have been the focus of discussion. Based on the results of previous researchers and practical data of Caidamu Basin, it is held that Aerjin Fault movement is multi phase, and the fault presented the trend of left lateral strike slip at least at the beginning of Miocene. Aerjin Fault has important effect on the evolution of the sedimentary structure of Talimu and Caidamu Basins, and therefore, it has a control effect on the western continental shelf and the migration and accumulation of petroleum in the two basins.
