摘　　要：上庄地区金矿床位于招远-平度断裂带南段,为胶西北重要的金矿密集区,NE向、NW向断裂在此交汇,成矿条件优越。区内已发现Ⅱ、8、9、10号脉4个金矿床,均受NW向次级断裂控制,呈雁列式排列,具有相同的成矿地质背景。近年来在Ⅱ、8号脉矿床深部新发现稳定的金矿体,具有较好的找矿潜力。该文通过地质构造特征总结,结合岩矿测试分析结果,开展了成矿地质背景和成矿规律对比研究,分析了成矿远景,为上庄地区乃至胶西北地区同类型金矿勘查与研究提供了参考。The gold deposit in the Shangzhuang area is located in the southern section of the Zhaoyuan-Pingdu fault zone.It is an important gold intensive area in northwestern Jiaozhou.NE and NW faults meet here,and the metallogenic conditions are superior.Four gold deposits of veinsⅡ,8,9,and 10 have been discovered in the area,all of which are controlled by NW-trending secondary faults,arranged in an echelon pattern,and have the same metallogenic geological background.In recent years,new stable gold ore bodies have been discovered in the depths of veinsⅡand 8,which have good prospecting potential.Based on the summary of geological structure characteristics,combined with the test and analysis results of rock and mineral samples,this paper has carried out a comparative study of the mineralization geological background and metallogenic laws,analyzed the mineralization prospects,and provided a reference for the exploration and research of the same type of gold deposits in the Shangzhuang area and even the northwestern Jiaozhou area.
