摘　　要：通过对九顶山铜钼矿区复式斑岩体特征、矿化特征、成矿作用之间关系的研究,初步将九顶山斑岩体岩浆活动可分为3期:第一期为正长斑岩、石英正长斑岩;第二期为斑状花岗岩与煌斑岩(a)组合;第三期为花岗斑岩与煌斑岩(b)组合;其中第一、二期与矿化关系密切。按照容矿围岩可分为斑岩型矿石、矽卡岩型矿石、角岩型矿石和煌斑岩型矿石4类;按成矿元素组合可分为钼矿、钼铜矿、铜矿、磁铁矿、金矿等类型;铜、钼矿化与石英钾长石化带和石英绢云母化带关系密切。Based on research of ore-body characteristics, mineralization characteristics and mineralization of composite porphyry in Jiudingshan copper-molybdenum deposit district, the porphyry magma activities in Jiudingshan is preliminarily divided into three phrases. The first phrase consists of syenite porphyry and quartz syenite porphyry;the second phrase in- cludes the combination of porphyritic granite and lamprophyre （a） ;the third phrase is the combination of granite porphyry and lamprophyre （h） ;Among these, the first and the second phrases are closely related with the mineralization. In accord- ance with the ore-hosting surrounding rocks, the ore deposit is divided into four types of porphyry ore, skarn ore, homfels ore and lamprophyre ore. According to the ore-forming elements, the deposit is divided into molybdenum ore, molybdenum-cop- per ore, copper ore, magnetite ore and gold ore. Copper and molybdenum mineralization is closely related with the quartz-K- feldspar zone and the quartz-sericite zone.
