Title: Zircon U-Pb Age of Tonghualing Intermediate-Acid Intrusive Rocks,Eastern Junggar,Xinjiang
Abstract: Tonghualing intermediate-acid intrusive rocks is located in Yemaquan arc between Armantai fault and Kelameili fault,Eastern Junggar,North Xinjiang.The intermediate-acid intrusive rocks are principally composed of diorite-porphyry,tonalite and monzogranite.Zircons from these rocks are dated using LA-ICP-MS U-Pb method and yield weighted mean 206Pb/238U age of 427.4±3.2,422.8±3.2 and 418.5±2.6 Ma respectively,indicating that there are Early Paleozoic magmatic activities in Eastern Junggar.This work supplies evidence for orogenic evolution in Early Paleozoic in this area.
