    摘要:

    山东省乳山市于家圈金矿床位于胶莱盆地东北缘,牟乳成矿带西侧,矿区内与金矿关系密切的地层、构造和岩浆岩发育,成矿地质条件良好。通过地物化综合找矿方法,在矿区内发现8条金矿化蚀变带,圈定4个金矿化体、1个银矿化体、1个铅矿化体、4个金矿体、1个铅矿体,取得了良好的找矿效果。在分析区域成矿地质背景的基础上,详细阐述了于家圈金矿地质特征,总结了控矿因素和找矿标志,探讨了找矿前景,认为该区找金矿潜力较大。

    Abstract:

    Yujiaquan gold deposit is located in the northeast margin of Jiaolai basin and the west of Mouru metallogenic belt. Development of the strata, structures and magmatic rocks closely related to gold deposits in the mining area and the metallogenic geological conditions are good. In this work, through comprehensive prospecting method of geological, physical and chemical, eight gold mineralization alteration zones have been found in the mining area, and four gold mineralization bodies, one silver mineralization body, one lead mineralization body, four gold deposits and one lead ore body have been delineated. Good prospecting results have been achieved. Based on the analysis of regional metallogenic geological background and geological characteristics of the mining area, geological characteristics of Yujiaquan gold deposit have been introduced in detail, the ore controlling factors and prospecting indicators have been summarized, and prospecting prospects have been studied. It is believed that the potential for gold exploration in this area is great.
