摘　　要：Objective The Xiemisitai area,located in the northern part of West Junggar,Xinjiang,is the eastern extension of the Boshchekul-Chingiz volcanic arc in China,which is characterized by a large number of Paleozoic volcanic rocks and intermediate-acid intrusive rocks.Recent studies show that the formation time of a large number of intermediate-acid intrusive rocks formed in the arc environment in the Xiemisitai area dates to the Late Ordovician(Wang et al.,2017)to Early Devonian(Wang et al.,2018).
