Hydrothermal rutile U-Pb dating of gold mineralization in the Jiangnan Orogen: A case study of the Hengjiangchong gold deposit in northeastern Hunan

•Yield the age of rutile to determine the absolute age of mineralization in gold deposits is feasible.•Hydrothermal rutile from auriferous quartz veins can represent the age of gold mineralization of Hengjiangchong deposit.•U-Pb isotope analysis of rutile indicates a significant gold mineralization event during Caledonian in northeast of Hunan province of Jiangnan Orogen.
