The Gacun deposit is a typical Volcanic Hosted Massive Sulfide (VHMS) associated with Late Triassic seafloor calc-alkaline felsic volcanics. Studies of zircon ages, petrology, major and trace element geochemistry, Sr-Nd-Hf isotope geochemistry volcanic rocks from the Northern Yidun arc were undertaken in this paper. We reshaped magmatic system activity time, defined origin magma evolution, prop...
