摘　　要： 云南宁蒗地区喜山期斑岩带各斑岩体（群）地质特征、岩石地球化学等方面的研究表明，斑岩属含矿斑岩。斑岩体侵位的围岩各地层亦具一定的含矿性。随着斑岩带围岩含矿层位和斑岩岩浆含矿性的变化，斑岩型铜矿和斑岩体外接触带矿床也随之发生变化，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ＳＮ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。 The studies of geology,petrology and geochemistry etc show that the porphyry rocks in Himalayan porphyry belt in Ninglang district are orebearing. The strata rocks intruded by the porphyry bodies have also somewhat orebearing property. The copper deposits of porphyry type and the deposits in the outer contact zone of porphyry bodies change with the orebearing layers of the country rocks and the orebearing property of porphyry magma in the porphyry belt,and so form a deposit series consisting of deposits of multiple metals and genetic types.The Himalayan Porphyry belt and its metallogenic series in Ninglang are strictly controlled by the arc fracture zone of BaoduBoluo.In fact,this porphyry belt is one integrating of structureporphyrymetallogenesis in Himalayan period.
