摘要

///Dahalajunshan volcanic rock is widespread in the area of Wusun Mountains, West Tianshan. Two LA-ICP-MS zircon U-Pb ages have obtained from the different location of volcanic rocks in the low stratum, respectively 353.3±3.5 Ma, 344±6 Ma. This paper proved that Dahalajunshan volcanic rocks in Wusun Mountains formed in the Late Devonian to Early Carboniferous.
