There were quite different opinions on age of Late Paleozoic strata and its tectonic evolution in Bogda Mountain, Xinjiang, which mainly consist of Carboniferous marine volcanic-sedimentary rocks including two periods of bimodal volcanic rocks but little granites. In this paper, age recalibration and provenance analysis of Late Paleozoic strata were done by LA-ICPMS U-Pb isotope dating of detrital zircons of two sandstones from Late Paleozoic strata in northern Bogda Mountain with published zircon U-Pb age of magmatic rocks, as well as Late Paleozoic tectonic evolution constrained by variation of detrital provenances was offered. The highest peak of wide detrital zircon U-Pb age range of sandstone sample from upper subgroup of Bogda Group was between 343～284 Ma(80%)with minor peaks between 386 Ma and 375 Ma(3%), 503 Ma and 441 Ma(7%), and 871 Ma and 735 Ma(10%). While the age of sandstone sample from Lucaogou Formation was highly concentrated between 358 Ma and 279 Ma(97%)with 257 Ma and 251 Ma(3%). Upper subgroup of Bogda Group should belongs to Early Permian rather than Late Carboniferous, and be equivalent with Lower Jijicao Group in southern Bogda Mountain. The Permo-Carboniferous boundary was suggested to be unconformity between lower and upper subgroup of Bogda Group or Julideneng and Shaleikesaier Formation. The detrial material of northern Bogda area during Permian was from northern and southern binary provenances, therein the mainnest provenance was the northern during Early Permian while the southern during Late Permian. The variation of detrial provenances indicated two periods of tectonic uplift during Late Carboniferous and Middle Permian. Refering to research on volcanic and volcaniclastic rocks, the tectonic evolution during Late Paleozoic era in Bogda Mountain was divided into four stages: back-arc rift basin during Early Carboniferous, collision during Late Carboniferous, post-collisional extension during Early Permian and uplift again to stable during Middle to Late Permian.
