Geochronological constraints on the Baguamiao gold deposit, West Qinling orogen, central China: Implications for ore genesis and geodynamic setting

The Baguamiao gold deposit, located in the Fengxian-Taibai ore district, is one of the largest gold deposits in the West Qinling orogen, central China. The poor age constraints on the gold mineralization event at the Baguamiao has caused strong debate on ore genesis and associated geodynamic controls. We carried out Sm-Nd and 40Ar-39Ar geochronological studies to determine more precise age constraints on the god deposition. The gold...
