乳山金矿床是胶东近年来探明的一个赋存在花岗岩中的石英脉型金矿床。矿区出露的煌斑岩金含量较低，不可能是金矿化的重要物源者；成矿流体的成分与大气降水热液成分相类似，其氢、氧同位素值也很好地反映了大气降水经不同温度和Ｗ／Ｒ比值条件下水岩交换后的分布特征；锶同位素研究则表明，成矿物质主要来自昆嵛山花岗岩体。
Rushan gold deposit is a quartz vein type gold deposit in Jiaodong proven in recent years. The gold content of lamprophyre exposed in the mining area is low and it can not be an important source of gold mineralization. The composition of ore-forming fluid is similar to that of hydrothermal components of the atmospheric precipitation, and its hydrogen and oxygen isotope values also reflect well The distribution of atmospheric precipitation after the exchange of water and rock under different temperature and W / R ratios shows that the metallogenic material mainly comes from the Kunyu Mountain granite.
