| 摘 要： | 蓬家夼金矿是山东乳山地区新发现的金矿类型，受荆山群中的层间滑动角砾岩系控制，沿胶莱盆地边缘莱阳组砾岩与荆山群副变质岩的构造接触带分布。矿体严格受层间滑动构造控制。在横、纵剖面上均呈连续的透镜状，每５０～１５０ｍ出现一次膨缩。矿体厚大部位产于层间滑动断层产状由陡（４５°～５０°）变缓（１５°～２０°）处。在上述认识的基础上，结合物化探方法，我们对蓬家夼金矿Ⅰ号矿体成功进行了预测。

| Abstract: | The Pengjiakuang gold deposit is a new type discovered from Jiaodong, occurring in interstratified glide breccia of the Jinshan Group parametamorphic rock series in the Mesozoic Jiaolai Basin. It is located at the contact between the conglomerates of the Laiyang Formation and the metamorphic complex of the Late Proterozoic Jinshan Group. We have studied the principal geological characteristics and spatial variation of the ore bearing structures, mineralization and occurrence and locating mechanics of ore bodies. With the help of geophysical and geochemical exploration methods, we succeeded in the prognosis of the deeply buried No. I ore body in the Pengjiakuang gold deposit. |
