摘　　要：灵山沟金矿床位于招掖成矿带中部,是一个兼具“玲珑式”“焦家式”双重矿化特征的典型矿床.该矿床的成矿演化过程大致可划分为4个矿化阶段:I.微量金一黄铁矿一石英阶段;Ⅱ.金一石英一黄铁矿阶段;Ⅲ.金一石英一多金属硫化物阶段;Ⅳ.少量金一黄铁矿一石英一碳酸盐阶段.不同阶段具有不同的矿化特征和成矿意义.Ⅱ、Ⅲ矿化阶段为主成矿阶段.上述认识在整个胶东金矿化集中区具普遍性意义.Lingshangou gold deposit is laocated at the middle portion of the famous Zhaoye gold belt. It has both 'Linglong-type' and 'Jiaojia-type 'dual minerogenetic characteristics. The evolution of the ore deposit formation is characterized by multiple stages, which can be classified into four ore-forming stages, viz. Ⅰ Au(trace)-Py-Q, Ⅱ. Au-Q-Py, in. Au-Q-Polymetallic-sulphides, W .Au(minor)-Py-Q-Carbonates. Each stage has different mineralization feature and metallization significance, among them, stage H and M are the major ones. This understanding mentioned above is of universal significance to the whole gold ore field in the Eastern Shandong.
