| 摘 要： | 对胶莱盆地蓬家夼与宋家沟两金矿的矿区地质特征，含矿岩系的岩石学，成矿元素，主量元素，微量元素，稀土元素以及碳、氧，硫稳定同位素等地质地球化学特征进行研究。结果表明；两矿床中金矿体的形成和分布受莱阳群及其中的断裂控制，莱阳群既是含矿层，又是矿源层，含矿岩系主要为陆源碎屑岩类，其沉积环境为河、湖相，讨论了含矿岩系的成岩及成矿作用机理。

| Abstract: | The aulhors investigate geological features and ore - bearing rock series in term of its petrology, ore - forming e1ements, main and trace el-ements, REE, carbon, oxygen and sulfur isotope at Pengjiakuang and Songjiagou gold deposit. The results show that the Laiyang group and related faultscontrol the distribution of gold orebodies. The Laiyaang group is ore - bearing and source beds. The ore - bearing rock series are mainly detrital rock andit's sedimentary environment is river and lake. The mechanism for diagenetic and ore - forming process of ore - bearing rock series are discussed. |

| Keywords: | stratabound gold deposit ore- bearing rock series diagenetic and ore - forming process Jiaolai basin |
