The Luziyuan super-large Pb-Zn-Fe polymetallic ore district is located in the southern section of the BaoshanZhenkang block, which is an important part of the Pb-ZnCu-Fe-Sn-Au polymetallic metallogenic belt, SW China. Previous researchers have suggested that the metallogenic materials of the Luziyuan Pb-Zn-Fe polymetallic deposit were mainly derived from concealed intermediate-acid granite. The Muchang alkali granites are located in the southeast of the Luziyuan ore district, which were suggested to the “sister” rock of the unexposed granite host in Luziyuan Pb-Zn deposit, but these granites lack of systematic and precise age. Furthermore, the formation of these rocks is very important for understanding the tectono -magmatic activities in Zhenkang block and the tectonic evolution of Tethys orogenic belt. In this work, we determined the LA-ICP-MS zircon U-Pb ages of the Muchang alkali granites in order to constrain the time limit of tectono-magmatic activities in Muchang.
