Zircon U-Pb dating, Geochemical Features of the Halunwusu Composite Granites at the Northern Edge of Southern Qilian, Qinghai.

The article presents a study which discusses geochemical features of the Halunwusu composite granites at the Northern Edge of Southern Qilian, Qinghai in China. It mentions that early adamellite to granodiorite is characterized by the mass fraction of silicon oxide. It also reveals that several island arc instructive rocks are distributing in the Tanjianshan volcanic arc belt.
