英文摘要	Based on reginoal geology, former researchers proposed that the Lailisigao'er Cu-Mo deposit was formed during Caledonian magmatism and mineralization. In this paper, we report new geochronologic data on host rocks, molybdenite and quartz from ores, which suggest that the Lailisigao'er Cu-Mo deposit and its host rocks were formed during Hercynian magmatism of the later stage of Devonian or early stage of Carboniferous. The SHRIMP U-Pb age of zircon and Rb-Sr isochron age of granodiorite, which is the host rock of the Mo mineralization, are 362 +/- 12Ma (95% conf.) and 350 +/- 15Ma (95% conf.), respectively. The Re-Os isochron age of molybdenite and Rb-Sr isochron age of quartz from ores are 359 +/- 8Ma (95% conf. and 341 +/- 9Ma (95% conf.), respectively. Hence, the Lailisigaol'er Cu-Mo deposit has the same age as the Axi gold deposit genetically related to continental volcanism) and the Lamasu copper deposit (porphyry-skarn type deposit in the Boluohuoluo uplift belt on the north margin of the Tulasu volcanic basin) in the region, which are in good agreement with a convergent tectonic setting of island arc during the later stage of Hercynian regional plate movement for the studied area.
