三山岛北部海域金矿床位于胶东西北部三山岛成矿带北段,是一个严格受断裂控制的超大型破碎蚀变岩型金矿床,矿体全部赋存于滨海海域之下。海域金矿在哪找,怎么找,是困扰海上找矿取得突破的重要难题。在综合分析研究海域金矿成矿规律及矿体空间分布、富集规律与预测找矿潜力的基础上,开展了一次系统的由预查开始直接进入详查的勘查活动。在勘查过程中,采用拼装式插桩海上钻探平台进行海上大规模钻探施工,该钻探平台具有安全稳固、可操作性强、周期短、可施工深孔及质量可靠等优点。海域金矿勘查工作历时2年半,先后取得如下重要成果:(1)提交了目前国内最大规模金矿床和最大金单矿体;(2)首开我国浅海海域金矿勘查的先河,解决了海上金矿勘查的关键技术难题,克服了海域金矿海上勘查难度大的问题;(3)丰富了胶东金矿成矿规律研究内容,有效应用新型找矿方法,对我国今后海底固体矿产勘查具有一定的借鉴意义和勘查示范作用。

Gold deposit is an extending part of metallogenic belt in Sanshandao northern sea area.Where and how to find the gold deposit have been an important problem that troubled marine prospecting for achieve breakthrough.To carry out a systematic exploration activity from the reconnaissance to general exploration directly based on the comprehensive analysis of the metallogenic regularity,orebody spatial distribution,enrichment regularities and forecasting prospecting potential.The assembling pitching of pile offshore drilling platforms are used in the exploration characterized with safe and stable,strong operability,short cycle,construction of deep hole and good quality.After two and a half years of exploration,the largest gold deposit and the largest gold ore body in China are presented.It is the pioneer in the gold exploration in shallow sea area,solving the technical problems in the gold exploration in the sea,creating a precedent for the gold exploration in the sea,overcoming the problem of the exploration difficulties in the sea area,broadening the research on the metallogenic regularity of Jiaodong gold deposit and the application of the new method for prospecting.It has certain reference significance and exploration demonstration effect to the solid mineral exploration in the future in our country.
