【摘要】：普朗铜矿是位于三江成矿带南段的超大型铜多金属矿床,对该矿首采区、矿区东部、矿区北部及矿区外围北部四个矿段的矿体特征、矿化特征、围岩蚀变等地质信息进行了对比分析。结果表明,首采区深部及矿区北段产出矿体均属于典型的斑岩型铜矿,矿体受蚀变控制作用明显,矿(化)体常产于钾化、硅化带、绢英岩化及其叠加部位,矿化强度与蚀变强度呈正相关;矿区外围东部大脉状矿体及矿区外围北部铅锌矿(化)体属热液脉性矿体,主要受构造控制,多产于近东西向的节理裂隙中。在对各矿段找矿标志的总结基础上指出首采区的近地表、构造交汇部位及矿区北侧深部均具有较好的找矿前景。
[Abstract]:Plang Copper Mine is a super large copper polymetallic deposit located in the southern section of Sanjiang metallogenic belt. The orebody characteristics and mineralization characteristics of the four ore bodies in the first mining area, the eastern part of the mining area, the northern part of the mining area and the northern part of the mining area are discussed. The results show that the orebodies in the deep part of the first mining area and in the northern section of the mining area are typical porphyry copper deposits, and the orebodies are obviously controlled by alteration, and the orebodies often occur in the potassium and silicide zones. There is a positive correlation between the mineralization intensity and the alteration strength in the sericite and its superposition, and the large vein ore body in the eastern part of the ore area and the lead-zinc ore body in the northern part of the ore area are hydrothermal vein orebodies, which are mainly controlled by the structure. Based on the summary of prospecting marks in each ore section, it is pointed out that the near surface of the first mining area, the position of tectonic intersection and the depth of the north side of the mining area have good prospecting prospects.
