Abstract
The Changjiang uranium ore field (CUOF) is one of the most important and representative granite-type uranium ore fields in South China. Previous work on the CUOF has primarily concerned uranium ore genesis, focusing on aspects such as timing of metallogenesis and uranium mineralization mechanisms. However, the exhumation history and preservation of the ore deposits in the CUOF are poorly constrained. This study reports multi-system low-temperature thermochronology data that constrain the thermal history of the CUOF in the south-central Zhuguangshan complex, providing important insights into its tectonic evolution and the degree of ore preservation. Zircon (U-Th)/He (ZHe) ages of the minerali..
