| 摘 要： | 通过对园珠顶斑岩型铜钼矿床地质特征的详细观察，结合对各阶段包裹体及H、O同位素的测试结果，认为成矿流体主要来自于岩浆，并与少量大气降水相混合。园珠顶矿床中辉钼矿与黄铜矿产状及成因机制不同，辉钼矿主要来自于成矿斑岩体，大气降水的参与以及钾化蚀变作用是导致辉钼矿沉淀的主要原因，而黄铜矿应为成矿流体长时间与围岩交代的产物。

| Abstract: | Through the detailed observation of the geological characteristics of Yuanzhuding porphyry Cu-Mo deposit，and combining with the tests on the inclusions at each stage and H，O isotope，it is considered that the ore-forming fluids mainly come from the magma，and are mixed with small amounts of atmospheric precipitation.In Yuanzhuding deposit，the occurrence and its ore-forming mechanism of molybdenite are different from that of chalcopyrite.Molybdenite is mainly from the porphyry ore-body，and the atmospheric precipitation as well as the K-metasomation is the main reason for molybdenite precipitation.While chalcopyrite should be the product under the metasomatism of ore-forming fluids with surrounding rock for a long period of time. |
