The ages of the volcanic rocks from the bottom of lower Fm. of the Shimaoshan Group in the Zijinshan Cu-Au orefield, Fujian Province, were dated using in-situ LA-ICP-MS zircon U-Pb method. Combined with previous results, the Cretaceous magmatic activities in the Zijinshan Cu-Au orefield can be divided into three stages: 1) 115～110 Ma is the early stage of volcanic eruption-overflow; 2) 110～105 Ma is the middle stage of volcanic overflow-concealed explosive-filling the volcano channels and intrusion of the Sifang pluton; and 3) 105～95 Ma is the late stage of emplacement of multistage porphyry granite and formation of hydrothermal-porphyry mineralization.com:office:office" />
