摘　　要：通过对九顶山不同岩体的形成时代及相互穿切关系的分析,将岩浆活动分为四个阶段:Ⅰ阶段为正长斑岩;Ⅱ阶段为斑状花岗岩和早期煌斑岩组合;Ⅲ阶段为花岗斑岩;Ⅳ阶段为晚期煌斑岩。岩体特征及矿化关系表明与铜钼成矿关系较密切的为花岗斑岩,因此Ⅲ阶段花岗斑岩为铜钼矿主要成矿岩体。Based on the analysis of the formation age and wear-cut relationship of the different rock of Jiudingshan Mountain,the magmatic activity is divided into four stages：Ⅰ stage for long porphyry;Ⅱ stage for the combination of porphyritic granite and early lamprophyre;Ⅲstage for granite porphyry;Ⅳstage for late lamprophyre.Rock mass characteristics and mineralization relationship show that granite porphyry has closer relations with copper and molybdenum mineralization,so,Ⅲstage granite porphyry copper and molybdenum is the main metallogenic rock body.
