摘　　要：Objective West Junggar,which is located in the southwestern segment of the Central Asian Orogenic Belt(CAOB),is an important tectonic unit in the evaluation and examination of the largest continental accretion on Earth,playing a significant role in understanding the tectonic evolution and crustal growth within the orogenic belt(Xiao and Santosh,2014).However,no precise record of ancient continental blocks is found in West Junggar,owing to the extensive coverage and later structural reconstructions.
