摘要：

<正>新生代印度—欧亚板块持续碰撞导致了青藏高原的隆升及陆内大型边界断裂的形成（Yin and Harrison,2000）.阿尔金断裂系是地球上规模最大的走滑断裂系统之一（Molnar and Dayem,2010），长1 600 km，由NEE走向的阿尔金左旋断裂和北侧的北阿尔金断裂以及两断裂之间夹持的菱形阿尔金山脉组成（Cowgill et al.,2003).作为青藏高原北缘主控边界，阿尔金断裂系统在印度—欧亚板块碰撞过程中对高原地壳变形起到了重要的调节作用.一种观点认为阿尔金断裂表现为左旋走滑运动，而北阿尔金断裂表现为逆冲性质为主，左旋走滑量有限，小于30 km(Yue and Liou,1999;Yue et al.,2004）.
