摘　　要：胶莱盆地东北缘龙口金矿脉岩发育情况良好:主要有煌斑岩、闪长玢岩、正长斑岩、花岗斑岩,其中煌斑岩与金矿关系最为密切。通过研究认为龙口金矿脉岩存在多期性,成矿前脉岩主要为金矿成矿流体寻找成矿空间,并对金矿脉形成阻隔“盖层”;成矿期脉岩与金矿成矿物质共用同一构造,交相呼应,相互伴生;成矿后脉岩主要对金矿脉造成切割破坏。The Longkou gold ore vein rocks in the northeastern margin of Jiaolai Basin are well developed:mainly lamprophyre,diorite porphyry,syenite porphyry and granite porphyry,among which lamprophyre is most closely related to gold deposits.Through research,it is believed that the dyke rocks of the Longkou gold deposit are multi-periodic.The oreforming fore dykes are mainly gold ore-forming fluids to find metallogenic space,and form a barrier"caprock"for the gold ore veins;The materials share the same structure,echo each other and are associated with each other;the vein rocks after metallogenic mainly cause cutting damage to the gold veins.
