Реферат:	eng: The Junggar basin contains an almost continuous section of Late Carboniferous-Quaternary terrigenous sedimentary rocks. The maximum thicknesses of the stratigraphic units constituting the basin cover make up a total of similar to 23 km, and the basement under the deepest part of the basin is localized at a depth of similar to 18 km. Both the folded framing and the basin edges have undergone uplifting and erosion during recent activity. These processes have exposed all the structural stages of the basin cover. Considering the completeness and detailed stratigraphic division of the section, we can determine the exact geologic age of intense mountain growth and erosion periods as well as estimate the age of orogenic periods by interpolating the stratigraphic ages. During the Permian orogeny, which included two stages (255-265 and 275-290 Ma), the Junggar, Zaisan, and Turpan-Hami basins made up a whole. During the Triassic orogeny (210-230 Ma), the Junggar and Turpan-Hami basins became completely isolated from each other. During the Jurassic orogeny (135-145 and 160-200 Ma), the sedimentation took place within similar boundaries but over a smaller area. During the Cretaceous orogeny (65-85 and 125-135 Ma), the mountain structures formed mainly at the southern boundaries of the basin and along the Karamaili-Saur line. The Junggar and Zaisan basins were separated at that time. The Early and Middle Paleogene were characterized by relative tectonic quiescence. The fifth orogenic stage began in the Oligocene. The recent activity consists of two main stages: Oligocene (23-33 Ma) and Neogene-Quaternary (1.2-7.6 Ma to the present). (C) 2013, V. S. Sobolev IGM, Siberian Branch of the RAS.
