摘　　要：阿尔金断裂左旋走滑的同时,伴随较大的逆冲分量,总体成花状构造,引起阿尔金山的垂向隆升,大量证据表明阿尔金山自中生代以来主要经历了6次快速隆升事件,即白垩纪、晚始新世—早渐新世、早中新世、中中新世、上新世、早更新世末—中更新世初。新生代的五期重要的隆升事件,与欧亚大陆拼合后的印度板块持续向北的挤压有关,俯冲引起青藏高原的阶段性快速隆升,是阿尔金山隆升的动力学机制。Altyn sinistral strike-slip fault, associated with a large thrust component, formed a positive flower-like structure in appearance. It was the fault that caused the vertical uplifting of Altyn Mountains. Many evidences indicate six uplifting events since Mesozoic in the Altyn Mountains, which happened in Cretaceous, late Eocene - early Oligocene, early Miocene, mid-Miocene, Pliocene, and late early Pleistocene-early middle Pleistocene, respectively. The Cenozoic uplifting is related to the northward continuing subduction of the India Plate after collision with Eurasian Plate, which gives rise to pulse-style rapid uplifting of the Qinghai-Tibet Plateau, and also offers a dynamics for Altyn Mountain uplift.
