Diagenetic and metallogenetic ages of Wuxing Pt-Pd deposit in Jidong of Heilongjiang Province has been uncertain for a long time. Single zircon SHRIMP U-Pb dating from mineral-bearing rock body indicates that the ages of 12 group s of experimental data are 35.8-40.3 Ma, the weighted mean age is 37.79 ±0.76 Ma. Com-bining with the characteristics of zircon CL image, the authors comfirm that the diagenetic time of Wuxing mineral-bearing rock body and the metallogenetic time of Cu-Ni and Pt-Pd are Late Eocene. Considered the formation time being consistent to the eruption event of alkali basalt magmatic in Dunmi fracture zone, it is concluded that the formation environment was related to Dunmi fracture, which shows the direction to look for Cu-Ni, Pt-Pd deposits in Northeast China.
