| 摘 要： | 通过对阿尔金山各边界断裂性质和阿尔金南缘断裂构造活动特点的系统分析,结合阿尔金山与南塔里木地块岩石建造组合特征进行比较,认为阿尔金山原属于南塔里木地块的组成部分,长城纪以后逐渐转化为南塔里木地块边缘活动带。其3条边界断裂分属于不同的断裂系统,具有各自不同的形成和演化历史。阿尔金南缘断裂活动的力学性质、运动方向具有多级周期性反复的特点,较好地揭示了阿尔金地块地壳波浪状构造演化特征。

| Abstract: | Through the systematic analysis of the faults in Altyn mountain and the tectonic nature of southernmarginal fault of Altyn as well as petrographic formation comparison between Altyn Mountain and South Tarimblock,it is considered that Altyn is a part of South Tarim block till Changchengian Period. After ChangchengianPeriod, Altyn gradually became a marginal mobile belt of South Tarim block. The three marginal faults of Altynbelong to different tectonic systems and have different evolution histories. The activity of South Altyn fault ischaracterized by multi-stages and cyclical repeat both in dynamic property and movement direction, which showsthe wavy tectonic evolution characteristic of Altyn. |
