1.西天山地质史中新构造阶段的独立性西天山的地质发展史可明显地分为三个阶段,即地槽、地台、地台期后造山或最新构造阶级。老第三纪时西天山成为具有稳定构造状态的典型地台,经受过缓慢沉陷,从而转为广阔的海侵区。始新世末期地台状态达到顶盛时期。此时海水不仅到达山间坳陷,也淹没了土尔其斯坦一阿赖山,恰特卡尔一库拉明山、努拉京山等现代山地及全部中克孜耳高原。当时大陆和正向地形只分布在费尔干山脉硬其东部。
1. West Tianshan geological history of the independence of the new tectonic stage West Tianshan geological history can be clearly divided into three stages, namely, the trough, platform, platform after the orogeny or the latest structural class. In the old Tertiary period, the western Tianshan became a typical platform with a stable tectonic state. After being slowly subsided, it became a vast transgressive area. Late Eocene platform state reached the peak Sheng period. At this time, the sea water not only reached the mountainous depression, but also inundated the modern mountainous regions of Turkmenistan-Araya, Chakkar-Kuramin and Nurajangshan, as well as all the middle-Kizils plateau. At that time, the mainland and the forward terrain were only distributed in the eastern part of the Falkan Mountains.
