GEOLOGY AND METALLOGENESIS OF COPPER DEPOSITS IN THE REGION OF CHANGBAI, CHINA AND HYESAN, DPRK

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.
