云南宁蒗地区喜山期斑岩成矿带地质特征

通过对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，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．随着斑岩带围岩含矿层位的变更和斑岩自身含矿性的变化，斑岩型铜矿和斑岩体外接触带矿床（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．

Geological Characteristics of Metallogenetic Series on Himalayan Porphyry Belt in Ninglang Area of Yunnan

Based on the research on porphyry property in geology,pertrochemistry,trace element and so on,this paper concludes that porphyry bodies on Ninglang Himalayan porphyry belt are mineralbearing.And so are their wall strata.In pace with mineral bearing 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 were made up of a series of different types of ore and deposit.Ninglang Himalayan porphyry belt and relative metallogenic series are strictly controlled by nearly north southern bogen fault of Baodu Boluo.The porphyry belt is also a relative strcture belt and a relative mineralization belt.
