  • 研究目的

    随着黔西南戈塘地区豹子洞等浅表红土型金矿开采资源的逐渐枯竭,寻找深部接替资源的任务已经十分迫切。从区域成矿规律、物化探异常、典型矿床特征等成矿预测要素出发,戈塘地区海马谷控矿断层北西侧下盘深部二叠纪茅口组、龙潭组之间的碳酸盐岩与碎屑岩Si/Ca界面上具有较大地寻找“层控型”金矿床的找矿前景。

    研究方法

    引入了宽频大地电磁法查明了海马谷断裂西南段0~2 km深部的电性结构特征,从电阻率反演断面图中的低阻带异常特征推断海马谷断裂具有多期活动特征,早期(中二叠世前)表现为张性正断层性质,倾向北东;后期(早三叠世后)表现为压性逆断层性质,倾向南东,倾角70°~80°。从电阻率反演断面图中的高低阻等值线梯度带推断茅口组与龙潭组存在古岩溶地貌特征,在深部存在相对“隆起”和“凹陷”变化。

    研究结果

    综合本区典型矿床的成矿模式、找矿标志和区域物化探异常特征,认为处于“空白”状态的海马谷断裂北西盘深部值得部署探索性钻探工程,揭示其深部的资源潜力。

    结论

    浅深结合的勘查技术方法(组合元素化探异常+宽频大地电磁探测技术)能够为靶区优选提供证据支撑,邻近海马谷断裂的P2/P3、Si/Ca界面相对“隆起”位置是开展钻探验证工作的有利位置。
