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，有望实现矿点向矿床的转变
The main types of gold deposits in the eastern part of Shandong Rushan are Rushan and Tongling. Among them, the Rushan-type gold deposits are distributed in four steeply inclined NNE left-row right-order compressive-shear fractures in the Kunlun Mountains. Gold mineralization has the obvious feature that it is distributed along the same ore-controlling fault zone Of adjacent gold deposits, the direction of the side of the ore body is the opposite. Based on the study of the localization structure of vein-shaped gold deposits in the area, it is proposed that the Rushan-type gold deposits have the features of NNE-trending and NE-trending, and the ore body localization is controlled by NNE and NE-trending fractures. Based on this, it is pointed out that Duanjia Xishan gold deposit and Matai stone gold deposit are structurally favorable sections of metallogenesis. After preliminary revelation of the project, the two ore deposit sites have shown a good prospecting prospect and are expected to realize ore deposit to deposit Change
