Muscovite Ar-40/Ar-39 and in situ sulfur isotope analyses of the slate-hosted Gutaishan Au Sb deposit, South China: Implications for possible Late Triassic magmatic-hydrothermal mineralization
The Gutaishan deposit is a slate-hosted Au–Sb deposit in the Xiangzhong metallogenic province, South China. The deposit has proven reserves of ca. 9 tonnes (t) of gold with an average grade of 13 g/t and 2,500 t of Sb with an average grade of 10%. In this study, muscovite 40Ar/39Ar and in situ sulfur isotope analyses of pyrite and arsenopyrite were performed to determine the mineralization age and the plausible source of S and Au. The 40Ar/39Ar dating result of muscovite limits the formation...[Show more]
