摘要
招平断裂带是胶西北重要的控矿构造带之一,其南段是下一步重点找矿地区。本文描述了南段已发现的金矿床地质特征,研究了其成矿规律。结果认为,"S"形构造控制矿床产出,不同构造性质决定了矿床类型。根据地层、构造、岩浆岩,各类异常、矿化信息,建立了区域勘查模型和矿床勘查模型,其中构造要素和蚀变矿化标志是重要的成矿要素。进一步指出在萌山-黄同段、张家庄-山旺段应加强勘探工作,已知矿床深部和外围有较大的找矿潜力。
The Zhaoping fauh zone is one of the important ore controlling structures in northwestern Shandong Province,and its southern section is the focus of the next step prospecting . This paper presents the geological features of the found gold deposits, and analyzes their metallogenic laws. It is noted that the S-shaped structure controls the occurrence of the deposit, and deposit types are determined by different structural properties. Based on data of stra- ta,structure,magmatic rocks,all kinds of anomalies and mineralization information,a regional exploration model and deposit prospecting model are estab- lished. It suggests structural elements and alteration mineralization marks are important factors of mineralization. It is further pointed out that the Mengs- han-Huangtong section and Zhangiiazhuang-Shanwang section should be receive strengthened exploration work. The deep subsurface and periphery of known ore deposits have a great potential of searching for more ores.
