Abstract: Jimunai Formation is located in Sawuer area of west Junggar basin, which is mainly composed of lava, pyroclastic rocks, and sedimentary rocks. Basaltic andesite from the upper section is (294.0±1.4) Ma by LA-ICP-MS zircon U-Pb dating. The result indicates that the lava underwent crystallization during Early Permian. Combined with local paleontological fossil assemblages, Jimunai Formation was formed in Late Carboniferous or Permian. The SiO2 content varies from 48.10% to 54.35%, belonging mainly to basalt and basaltic andesite. The total FeO content is between 7.38%-10.92%, MgO content is between 3.35%-5.16%, and Mg# index is between 41.02-55.05, mainly belonging to tholeiitic series. The rare earth element (REE) distribution pattern is right deviated, and rich in LREE ((La/Yb)N=4.00-6.04), with slight fractionation of HREE((Gd/Yb)N=1.68-2.26), δEu=0.91-1.07, δCe=0.91-1.06. The trace element spider diagram shows the enrichment of LILE (Rb, Ba, Sr, P), and moderate depletion of HFSE (Nb, Ta, Ti) except for the samples of JM2 and JM3. The ratios of (Th/Nb)N are mainly between 1.39 and 2.10, and Nb/La are between 0.39 and 0.74, indicating that the magma was partially contaminated by the lithospheric mantle and the crust. Based on the geochemical characteristics of high Zr/Y ratio, high trace element contents, the volcanic rocks of Jimunai Formation was derived from basaltic magma of asthenospheric mantle upwelling under post-collision tectonic background, and the magma was partially contaminated by lithospheric mantle and crust in the process of ascending.

Key words: volcanic rocks, zircon U-Pb dating, tectonic setting, Jimunai Formation, west Junggar basin
