Age and geochemistry of the intrusive rocks from the Shaquanzi-Hongyuan Pb–Zn mineral district: Implications for the Late Carboniferous tectonic setting and Pb–Zn mineralization in the Eastern Tianshan, NW China

The Central Tianshan Terrane (CTT) in the Eastern Tianshan (Xinjiang, NW China) is an important Pb–Zn metallogenic belt and played a pivotal role in crustal evolution and collisional tectonics of the southern Central Asian Orogenic Belt. The Shaquanzi gabbro and Hongyuan granodiorite are located in the northern margin of the CTT and associated with Pb–Zn mineralization. Zircon U–Pb dating yielded weighted mean ages of 307.2 ± 1.5 Ma and 301.2 ±...
