| 摘 要： | 宁蒗地区喜山期斑岩带受近南北向的包都－波罗弧形断裂带控制，由壳幔混源型岩浆被动侵位而成，总体上呈向北逐渐倾伏的趋势。该斑岩带斑岩属钙碱性系列、中酸性岩类。通过对该斑岩带各斑岩体（群）地质特征、岩石化学特征的综合分析，表明其为含铜斑岩或铜（钼）斑岩，具良好的成矿前景。

| Abstract: | Formed by passive emplacent of crust_mantle mixed type of magma and controlled by nearly NS_trending Baodu-Boluo arcuate fault zone, the Himalayan porphyry belt in Ninglang area tends generally to plunge northward. Porphyry rocks in this belt are intermediate_acid rocks of calc_alkaline series. An integrated analysis of geological and petrochemical characteristics of various porphyry bodies(groups) in this porphyry belt show that porphyry bodies in this belt are cupreous or copper (molybdenum) ones which have good metallogenic prospects. |
