| 摘 要： | 普朗大型斑岩铜矿受区域地质、构造、地层、岩浆岩、岩体蚀变的综合控制,形成有其自身的特点和成矿条件。区域性断裂控制多期岩体侵入,形成普朗复式斑岩体;活动性差的硅铝质砂板岩形成岩体的天然屏障;不同期次构造交汇部位,形成密集的构造裂隙,为矿质的运移和积淀提供有利条件;多期多类型蚀变使矿质富集形成工业矿体。

| Abstract: | The large scale Pulang porphyry Cu deposit is comprehensively controlled by the regional geology, structure, stratigraphy, magmatic rocks and rockbody alteration, which has its genetic characteristics and metallogenetic conditions. The intrusions of multistage rockbody are controlled by the regional fault, which form the Pulang composite porphyry body. The inactive sialic sand-slate is a natural barrier. There are dense fissures formed in the intersection places of different stage structure, which provide the advantageous conditions for the moving and precipitation of ore material. And the multistage,polygeneous alterations cause the ore material to concentrate and form the industrial orebodies. |
