通过对构造变形、构造空间展布关系、断面产状变化以及构造应力场等的综合分析研究认为,阿尔金北缘活动断裂带在第四纪内的运动方式经历了由挤压逆掩为主(早更新世—中更新世初期)到左旋走滑兼具挤压逆冲(中更新世中、晚期)直至纯左旋走滑运动(晚更新世—现今)的逐渐转变过程.作用于这种转变,研究区内区域构造应力场的演变大致可以划分为三期,其主压应力轴方向由老至新依次为近南北向、北北东向和北东向.构造应力场和断裂带运动方式的这些变化主要是由于印度板块持续向北推挤导致青藏高原内部次级块体向东滑动、岩石圈物质向东流展而造成的.
Based on the comprehensive analysis of the tectonic deformation, the spatial distribution of structural space, the change of section shape and the tectonic stress field, it is considered that the movement pattern of the active fault zone in the northern margin of the Altun experienced a change from overturning to crusting during Quaternary (Early Pleistocene - Early Middle Pleistocene) to L-strike slip with the gradual transformation of crush thrust (mid-to late Pleistocene) until pure levitation-slip (late Pleistocene-present). For this transition, the evolution of the regional tectonic stress field in the study area can be roughly divided into three phases. The principal compressive stress axis direction is nearly north-south, north-north-east and north-east, from old to new. These changes in tectonic stress field and fault zone movement patterns are mainly attributed to the continuous northward thrust of the Indian plate resulting in the eastern block of the Qinghai-Tibet Plateau sliding eastward and the lithosphere material flowing eastwards.
