摘　　要：胶莱盆地及其周边地区近年来已先后发现了众多金矿床,根据产出位置,主要有:盆地边缘接触带金矿床(乳山蓬家夼、西涝口、辽上、土堆、沙旺、东刘家等),盆地内部金矿床(牟平发云夼、史家、次火山岩型五莲七宝山),盆地外围基地老地层中的金矿床(平度大庄子)。对这些类型金矿床的黄铁矿、金矿物的一些标型特征进行研究,从黄铁矿的粒度、形态、主成分、微量元素、含金性以及金矿物的成色、粒度、形态、赋存状态等方面的分析研究,判断了这些矿床的成因和产出深度,对该区找矿标志进行了确定,找矿方向进行了预测。A number of gold deposits were detected in and around Jiaolai basin in recent years,which are sorted according to their occurrence locations to basin margin contact zone gold deposits such as Rushan Pengjiakuang, Xilaokou, Liaoshang, Tudui, Shawang, DongLiujia; interior basin gold deposits such as Mouping Fayunkuang, Shijia, subvolcanic rock type Wulianqibaoshan; and gold deposits of ancient strata in outer basin base such as Pingdu Dazhuangzi. Typomorphic characteristics of pyrites such as their grain size, form, main component, trace elements and gold-containing property, and those of gold minerals such as their grade, grain size, form and state of occurrence are studied together with the metallogenesis and depth of these deposits, which contribute to the determination of prospecting indicators and the orognosis of Drosoecting direction.
