摘　　要：山东乳山中东部地区金矿类型主要为乳山式和铜岭式。其中乳山式金矿产在昆仑山岩体中，分布于４条陡倾的ＮＮＥ向左行右阶式压扭性断裂带上，金矿化有一明显的特点：就是沿同一控矿断裂带上分布的相邻金矿床，其矿体侧伏方向是相反的。通过对区内脉状金矿的定位构造研究，提出乳山式金矿具有ＮＮＥ向成带、ＮＥ向成行的特点，矿体定位受ＮＮＥ及ＮＥ向断裂的联合控制。并据此指出段家西山金矿点、马台石金矿点为成矿的构造有利地段，经过工程初步揭露，这两处矿点已显示出良好的找矿前景。The Rushan-type and Tongling-type gold deposits are typical gold de posits in the central and east part of Rushan, Shandong. The Rushan gold deposit is hos ted within Kunyushan granite and located at four sinistral steep compresso-shear faults. For the adjacent deposits located at the same ore-controlling fault, th eir orebodies take each other in the opposite direction. Study on the positionin g structures indicates that in the Rushan gold deposit, the allocation of orebod ies is characterized by NNE-trending belt and NE-trending row. The location of o rebodies is controlled by NNE-trending and NE-trending faults in company. It poi nt ts out that the Duanjiaxishan and Mataishi gold prospects represent sections str ucturally favourable for mineralization. It has been confirmed by engineering wo rks that these two gold occurrences have good economic prospect.
