摘　　要：本文讨论了胶东地区煌斑岩与金矿床在空间、时间和成因上的关系;初步确定煌斑岩能提供金矿床的部分成矿物质;指出煌斑岩具有较强的还原性能,是金沉淀富集的良好地球化学屏障。The lamprophyre in the Jiaodong area bears a relationship in time,space and genesis with gold oresrespectively.It has been confirmed that a part of the metallogentic materials was provided by the iam-prophyrc.Having a large reducing capacity,the lamprophyre is the best geochemical barrier for thedeposition and concentration of gold.
