浅海覆盖区金矿勘查技术方法组合探讨——以胶东三山岛北东浅海区找矿勘查为例

Study on the Combination of Prospecting Techniques and Methods for Gold Deposits in Shallow Sea Covered Area——Taking Prospecting and Exploration in the Northeast Shallow Sea Area of Sanshandao in Jiaodong Area as an Example

摘要:

在浅海覆盖区，常规的地质找矿工作开展难度较大，并缺少有效的技术方法，限制了浅海区找矿勘查工作。本文以三山岛北东浅海地区找矿勘查为例，采用重力测量+高精度磁法剖面测量+地震剖面测量+浅钻取样化探剖面测量+钻探的勘查技术方法组合，解译并控制了浅海覆盖区控矿构造，发现了金矿体。结果表明该技术方法在浅海覆盖区找矿勘查的有效性，对浅海覆盖区找矿勘查具有一定的参考价值。

Abstract:

It is difficult to carry out the conventional geological prospecting in the shallow sea covered area. The lack of effective technical methods restricts the prospecting and exploration. Taking the prospecting and exploration in the northeastern shallow sea area of Sanshandao as an example, by using the combination of exploration technologies and methods, such as gravity measurement, high precision magnetic profile measurement, seismic profile measurement, shallow drilling sampling geochemical profile measurement and drilling, the orecontrolling structures in the shallow sea covered area has been interpreted and controlled, and gold ore bodies have been discovered. As showed by the results, the combination of methods is effective in prospecting in shallow sea covered area. It can provide some references for prospecting and exploration in shallow sea covered area.
