    胶东焦家金矿田"三位一体"找矿预测地质模型与深部找矿示范

    The "trinity" prospecting prediction geological model and demonstration of deep prospecting of Jiaojia gold field in the Jiaodong area

    • 摘要: 焦家金矿田是胶东地区金矿最富集的三大金矿田之一。为开展焦家金矿田深部找矿预测工作, 在焦家金矿田深部调查工作总结的基础上, 运用勘查区找矿预测理论构建了找矿预测地质模型。结果显示, 早白垩世郭家岭型花岗岩是焦家金矿田的金矿成矿地质体; 成矿构造系统为焦家断裂构造系统, 成矿结构面主要包括主断裂面、次级断裂面、裂隙面等; 热液蚀变类型主要有钾长石化、黄铁矿化、绢英岩化、硅化、碳酸盐化等。以勘查区找矿预测地质模型为指导, 开展了深部找矿预测, 圈定了深部找矿靶区2处, 经钻探验证均取得了较好的见矿效果, 开拓了深部找矿空间。

       

      Abstract: The Jiaojia gold field is one of the three most abundant gold fields in the Jiaodong area.In order to carry out deep ore exploration and prediction work in Jiaojia gold field, the geological model of ore prospecting is constructed based on the summary of deep investigation work in Jiaojia gold field using the ore prospecting prediction theory in the exploration area.The results show that the Guojialing-type granite of Early Cretaceous is the metallogenic geological body of Jiaojia gold field.The metallogenic structural system is Jiaojia fault structural system and the metallogenic structure interface is fault structure, which mainly includes main fault surface, secondary fault surface, fissure surface and so on.Hydrothermal alteration mainly includes potash feldspathization, pyritization, quartz-sericitization, silicification and carbonation.Two deep ore prospecting target areas have been delineated, and good prospecting results have been achieved through drilling verification, thus opening up the deep prospecting space.
