| 摘 要： | 枪口南银多金属矿床地处东昆仑多金属成矿带东段,枪口—哈龙休玛海西-燕山期铁、银、铅、锌、铜、金、钼成矿亚带部分,成矿地质条件优越。枪口南银多金属矿区目前已圈定9条矿化带,21个矿体,主要矿种有金、银、铜、铅、锌、钼等,矿石类型主要为构造热液(脉)型铜铅锌银矿石、构造蚀变岩型金矿石。枪口南矿区构造-岩浆活动强烈,印支期—燕山期构造岩浆活动为矿区成矿提供了热源、成矿物质,区内NE向断裂控制区内金、铜、铅锌等矿体的产出,NW向断裂组控制着区内金、银矿(化)体。NW向断裂组,是区内重要控矿构造;区内中部发现的Ⅳ号含矿斑岩体,具有斑岩型矿床蚀变特征,显示其具有斑岩成矿条件。枪口南银多金属矿床成因有构造热液(脉)型、构造蚀变岩型和斑岩型。

| Abstract: | The Qiangkounan silver polymetallic deposit is located in eastern Kunlun metallogenic belt and Hercynian-Yanshanian Qiangkou-Halongxiuma Fe, Ag, Pb, Zn, Cu, Au and Mo sub-metallogenic belt and the geological and metallogenic condition is superior. In the Qiangkounan area 9 mineralization zones and 21 ore bodies are located at present. Au, Ag, Cu, Pb, Zn and Mo are the main ore types. And the ore is dominated by tectonic hydrothermal vein type Cu, Pb, Zn and Ag ore and altered cataclastic rock type Au ore. In the area tectonic-magmatism is strong, the Hindu-China tectonic-magmatism supply heat and ore material source, NE faults control Au, Cu Pb and Zn ore bodies, NW fault Au, Ag ore (mineralization) bodies and they are the main ore-control structures. In the center of the area is discovered a ore-bearing porphyry body IV. This porphyry body is characterized by alterations of porphyry type ore deposit and metallogenic conditions of porphyry ore deposit exist here. |
