沙鲁里山地质地貌显示,第三纪晚期形成的夷平面在上新世末第四纪初解体,在夷平面的一些部位出现裂谷盆地,接纳河湖相沉积,这是本区对青藏运动A幕的响应.此后高原持续脉动上升,由于构造断陷作用,兼之金沙江和雅砻江一些大的支流的伸入切割,形成若干断陷-河流谷地以及最早的阶地.至少在昆黄运动后的600-550 kaBP,本区夷平面一般达到约3500-3700 m的高度,与全球冰期气候相迎合,发生横断山系迄今发现的最早的冰川作用.与此同时,本区北部甘孜一带,出现与冰川作用相伴随的黄土沉积.末次冰期时,沙鲁里山已接近现在高度,发生了诸如稻城冰帽、新龙冰帽以及一些巨大的山谷冰川,留下了青藏高原最壮观的冰川堆积.
The geology and geomorphology of Shaluli Mountain shows that the flat surface formed in the late Tertiary Period was dissolved in the early Quaternary, with rift basins in some parts of the flat surface and receptive sediments of rivers and lakes, After the plateau continued pulsation rise, due to tectonic faulting, and the extension of some large tributaries of the Jinsha River and the Yalong River, a number of fault depressions - the valley and the earliest terraces were formed.At least, After 600-550 kaBP, the flattened area of this area generally reaches a height of about 3500-3700 m, which coincides with the global glacial climate and has the earliest glacier effect so far discovered in the Hengduan Mountains. At the same time, the northern part of Ganzi Loess sediments, which are accompanied by the glaciation, have reached the present height during the last glacial period, with ice caps, new dragon ice caps and some huge valley glaciers, leaving the most spectacular glacial accumulation on the Tibetan Plateau.
