Abstract: The Baizhangzi gold deposit is an important magmatic hydrothermal type of gold deposit in Lingyuan, Western Liaoning Province. The outcrop in the orefield is dominated by Dahongyu Formation of Changcheng System, which serves as the host rocks. The metamorphic series of Archean Jianping Group is the main resource bed of Baizhangzi gold deposit. The Baizhangzi ore body is the branch of Dazhangzi intrusive rocks, which intruded upward from deep crust and extracted oreforming material from Jianping Group, finally formed gold orebody in Dahongyu Formation. With analysis of the ore-forming process, the metallogenic model of Baizhang gold deposit is set up.
