Beizhan iron ore is one of the newly discovered medium-sized iron ores in Awulale mineralization of west Tianshan. Lower Carboniferous volcanic rocks are widely developed in the mine.This paper analyses the major elements, trace elements, REE geochemical characteristics and LA-ICP-MS zircon U-Pb dating and zircon Hf-Lu isotopes of the volcanic rocks, and discusses the tectonic environment of Dahalajunshan formation in the mine, diagenetic mineralization age and the source of the volcanic rocks. they belong to rich calc-alkalic series, and consist of basalt, basaltic andesite, andesite and liparite. They are dominated by mafic rocks.Trace elements and REE show that the tectonic environment of the volcanic rocks in the mine belongs to activities terrestrial volcanic island arc. LA-ICP-MS zircon U-Pb suggests that the formation time of granite mine in southern yield is an isotopic age of（301±0.93）Ma, which represents late Early Carboniferous, and its metallogenic epoch is early Late Carboniferous. According to its geological background, we conclude that Beizhan iron ore has two metallogenic periods at least, In the aspect of genesis, It is a magnetite deposits which had overlaid the volcanic sedimentary superposition and skarn.Zircon Hf-Lu isotopes shows that Beizhan iron ore rocks are from the Proterozoic, partial melting of Archean crustal material, and the source material there has been in the earth's crust for a long time.
