Abstract Changbai area in southeastern Jilin Province, China and Hyesan area of Korea, both located in the Proterozoic Liao-Ji rift, share similar geology settings. The geology, strata, intrusive rocks and ore-controlling structures of Linjiang copper deposit and Hyesan copper deposit are studied. The Linjiang deposit is characterized by skarn type of copper deposit; while the Hyesan deposit, porphyry copper deposit. They both belong to porphyry-skarn metallogenic system. The Changbai area has a good prospecting potential. The exploration should focus on the intersectional areas of NW, NE and EW faults, contact zones between Yanshanian acid-intermediate intrusions and pre-Cambrian strata, and mineralized alteration belt with characters of porphyry deposit.
