Since Tarim movement at the end of Pre-sinian

the west Manjiaer Depression has experienced about 6 major tectonic evolution stages. Sinian-Ordovician was the formation stage of intra-cratonic depression and Awati-Manjiaer( or A-Man) low ridge

which was a large

wide

low-amplitude one with the high point near Manxi-1 Well. Silurian-Devonian was the formation stage of intra-cratonic compressive bending depression and Lunnan paleo-uplift. Owing to the strong early Hercynian movement at the end of Devonian

Yingmaili-Lunnan paleo-uplift turned into two separate uplifts. At the same time

A-Man low ridge moved westward and was compressed into a narrow one. Carbonifernus-Permina was the formation stage of intracratonic rifting depression and inherited development of the Lunnan paleo-uplift

whereas the Triassic was the formation stage of quasi-foreland depression and deformation of the paleo-uplift. After the strong In-dosinian movement at the end of Triassic

the west Manjiaer region entered a new stage of inland depression and formation of Hadexun Uplift during the Jurassic to Paleogene. The Hadexun is a nose-shaped uplift dipping northeast

which is directly opposite to the trend of Lunnan plaeo-uplift. The Neogene was also an important stage

Manjiaer Depression

together with the North Tarim uplift

were changed into the foreland slope of Kuche foreland basin

and the Hadexun Uplift was finally fixed.
