英文摘要	The Barluk arc, situated in West Junggar, is an important component of the Kazakhstan domain in the Central Asian Orogenic Belt (CAOB). However, the nature of the Barluk arc (active continental margin or oceanic island arc) is in debate. The igneous rocks in the Shiwu area, Barluk arc, have diagnostic petrologic, geochronologic and geochemical signatures that uncover the attributes of the Barluk arc. In this paper, we report detailed petrology, whole rock geochemistry and Sr-Nd isotopic, zircon U-Pb dating and Hf isotopic data of igneous rocks in the Shiwu area. Our results reveal that: (1) except for 302.2 Ma gabbro, igneous rocks from Barluk arc in the Shiwu area are dioritic and granitic, have ages ranging from 323.8 to 310.5 Ma, and they have geochemical signatures originated from typical continental arcs, including calc-alkaline series rocks, enrichment of LILE, depletion of HFSE, and higher Th/Yb and Ta/Yb values; (2) the granitic porphyry and rhyolite in Barluk arc have old T-DM2(Hf) ages, up to 1091 Ma, suggesting the existence of Precambrian crust or similar materials as their sources; and (3) The 302.2 Ma gabbro dike has high values of epsilon Nd(t) (+ 7.54) and epsilon Hf(t) (+ 12.8 to + 15.5), and a young T-2DM (Nd) age (455 Ma), and therefore it was possibly related to upwelling of asthenosphere mantle in a post-subduction extensional tectonic setting. Based on these parameters, we suggest that the Barluk arc is defined as a Late Paleozoic continental margin arc along the margin of the Kazakhstan Continent. Westward subduction of the Junggar Oceanic plate in the Barluk area started in Early Devonian and continued to the Late Carboniferous (310 Ma). Subsequent post-collisional tectonic processes between the Junggar Oceanic plate and Kazakhstan Continent continued to the Late Carboniferous (302 Ma).
