In the early Permian large volumes of volcanic rocks developed in the Eastern Tianshan of the southern Altaids. The Shaerhu alkaline complex, which occurs along a NW-trending transcurrent fault in the Dananhu arc, is composed of alkaline gabbro intrusions, granites and rhyolites; the gabbros and rhyolites have similar zircon crystallization ages of 286.5±2.1Ma and 286.7±2.1Ma, respectively. The granitic...
Permian mafic and felsic intrusions occur along the Kangguer Shear Zone (KSZ) in the Jueluotage area, Eastern Tianshan, northwest China. This study focuses on the Permian felsic intrusions (288–276.2Ma). Systematic geological and geochemical investigations show that granite plutons in the western KSZ (Dikan, Guandao and Hongshi) have lower Al and higher alkali contents than those in the eastern KSZ...
