摘　　要：通过对宁蒗地区喜山期班岩带各斑岩体（群）地质特征、岩石地球化学等方面的研究，一致地表明其斑岩属含矿斑岩。斑岩体（群）侵位的各时代围岩地层亦具有一定的含矿性。随着斑岩带围岩合矿层位的变更和斑岩体自身含矿性的变化，斑岩铜矿和斑岩外接触带矿床（或矿化）也随之发生变化，形成由一系列多矿种、多类型矿床构成的矿床系列。宁蒗地区喜山期斑岩带及其成矿系列严格受近南北向的包都—波罗弧形断裂带控制，该斑岩带实为构造—斑岩—成矿三位一体的喜山期构造—斑岩成矿带。By studying on porphyry property of geology、petrochemistry、trace element and so on, the paper concludes that porphyry bodies on Ninglang Himalayan porphyry belt are pay ones. And their wall strata are also pay. In pace with pay property change of porphyry bodies and their wall strata,the types of porphyry copper and outer porphyry contact deposit also change,and then deposit series make up of a series of different types of ore and deposit. Ningang Himalayan porphyry belt and telative met-allogenic series are strictly controlled by nearly north southern bogen fault of Baodu Boluo.The por-phyry belt is also relative structure belt and relative mineralizatjon belt.
