摘要
李伍铜锌矿产于江浪变质(核)杂岩内[1],含矿岩系(李伍岩群)变质程度较高,已达绿片岩—角闪岩相,属中压变质相系,原岩恢复比较困难。分析认为李伍岩群原岩建造应归入火山—沉积岩建造,产于扬子陆台西缘元古代裂谷系的一个分支裂谷带中(已消亡)。
The Liwu Zn-Cu deposit is confined to the Jianglang metamorphic core complex, and the Liwu Rock Group as ore-bearing rock series is characterized by metamorphic degree of high greenschist facies to low-amphibolite facies. Study indicates that the original rock from which the Liwu Rock Group was derived is a volcanic-sedimentary formation in a rift zone on the western margin of the Yangtze platform.
