The results show that the magmatic activities in the West Junggar are divided into three periods. Late Silurian-Early Devonian magmatic event produced mainly Akeqiaoke, Ximisitai, and Saier granitoids, and Akeqiaoke granodiorites having geochemical characteristics of typical adakite resulted from the partial melting of subducted oceanic slab.refix = o ns = "urn:schemas-microsoft-com:office:office" />
