Zircon LA ICP-MS U-Pb analysis system was used to study metallogenic epoch of the Linjiang Copper deposit and age of the quartz diorite-porphyrite related to the formation of the deposit,Changbai area,Jilin Province.U-Pb dating results are two groups,the first one contains two captured detrital zircons with 206Pb/238 U ratio of 128.7±2.8 Ma and 131.4±3.78 Ma,the other group contains 16 zircons,which is interpreted to be the crystallization age of quartz diorite-porphyrite,with weighted mean 206Pb/238 U age of 122.6±1.1 Ma(n=16,MSWD=0.80),belonging to the middle of Early Cretaceous.Combined with previous studies,we consider that the Linjiang Copper deposit was formed in a subduction geodynamic settings of the Paleo-pacific Plate beneath the Eurasia Plate in the early Cretaceous.
