The Yili Block is one of the Precambrian microcontinents dispersed in the Central Asian Orogenic Belt (CAOB). Detrital zircon U–Pb ages and Hf isotopic data of Neoproterozoic meta-sedimentary rocks (the Wenquan Group) are presented to constrain the tectonic affinity and early history of the Yili Block. The dating of detrital zircons indicates that both the lower and upper Wenquan Groups have two major...
The Chinese Tianshan is the southernmost orogenic terrane located in the long-lived accretionary Central Asian Orogenic Belt. Granitoid rocks are extensively exposed in the Chinese Tianshan, especially in its central part, known as the Chinese Central Tianshan Block (CTB) and therefore recorded the formation of continental crust. However, the tectonic affinity and crustal evolution of the CTB are...
