| 摘 要： | 吉林东南部长白地区与朝鲜惠山地区均位于元古宙辽吉裂谷内,地质背景相似.本文分析了我国临江铜矿与朝鲜惠山铜矿产出的地质背景,对地层、岩体、构造控矿进行了解析.研究认为临江铜矿为夕卡岩型铜矿,惠山铜矿具有斑岩型铜矿的地质特征,两铜矿同属斑岩-夕卡岩型成矿系统.指出长白沿江地区具有良好的找矿前景.今后找矿工作应注意:北西向、北东向断裂与近东西向断裂交汇部位矿化线索;燕山期中酸性侵入岩与前寒武纪地层接触部位矿化勘查以及斑岩型特征矿化蚀变的甄别.

| 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. |
