海南岛戈枕含金剪切带煌斑岩与金成矿关系研究

在详细的矿床地质、岩石地球化学和同位素年代学综合研究基础上，结合区域构造演化的特点，着重对金矿与煌斑岩的成因关系进行了剖析，认为戈枕含金剪切带煌斑岩与金矿不仅具有生成构造环境上的联系，而且对金成矿具有重要的物源贡献，是金矿找矿标志。煌斑岩与金矿是长期的区域构造活动、岩浆活动事件耦合作用的产物。

RELATIONSHIP BETWEEN LAMPROPHYRE AND GOLD MINERALIZATION IN THE GEZHEN GOLD-BEARING SHEAR ZONE IN HAINAN PROVINCE

According to a synthetical study of geological features,petrochemistry and isotopic geo chronology of gold deposits,connecting with the characteristics of evolution of regional tectonics,the author emphasizes a genetic relationship between gold－ vein and lamprophyre.The result is that not only both of them were formed in the same tectonic setting,but also lamprophyre had an important mineral matter contribution to gold mineralization and are the marks for predicting gold deposits.The lamprophyre and gold deposits are the results of the coupling of tectono－ magmatic activity for a long time.
