阿尔金山北段阿克塞—当金山口一带的裂变径迹测年证据表明,该地区于9～7 Ma以来发生过快速抬升和剥蚀,并且一直持续形成了现今所见的阿尔金山。新生代以来至少经历了三次抬升:早期43.6～24.3Ma、中期19.6～13.6 Ma、晚期9～7 Ma。抬升速率先缓慢、后相对快速,9～7 Ma以来的抬升速率为0.94 mm/a。晚期的构造拾升可能与阿尔金断裂带左行走滑活动有关,而与相邻的柴达木盆地北缘地区的构造抬升并不一致。
Evidence from fission track dating from the Arkseed-Dankensikou area in the northern Altun Mountains shows that rapid uplift and erosion occurred in the area between 9 and 7 Ma and that the Altun Mountains are now continuing to form. The Cenozoic has undergone at least three uplifts: 43.6-24.3 Ma in the early, 19.6-13.6 Ma in the middle and 9-7 Ma in the late. The rate of ascent was slow first and then relatively fast, with the rate of ascent of 0.94 mm / a since 9-7 Ma. The late tectonic uplifts may be related to the left-lateral strike-slip activities of the Altyn Tagh fault zone and are not consistent with the tectonic uplift of the adjacent northern Qaidam basin.
