摘要
矿体的形成，尤其是矿体的赋存和保存与地质构造密切相关。目标勘查矿点构造控矿特征明显，为摸清勘查区内构造特征，圈定不同地质体及可能矿化体，我们使用DDS-3型甚低频电磁仪，结合高精度GPS开展地球物理勘查工作、圈定出一明显甚低频低阻异常，异常宽30～50m，断续分布，控制长200m。实践表明，使用甚低频磁倾角（D）测量法可以有效地揭示出勘查区内矿体及断裂构造的分布特征，为下一步研究及探矿工作提供初步依据。
Formation of orebodies and, especially, preservation of orebodies has close correlation with geological structure. It is obvious that orebodies are controlled by geological structures in the target area. In order to find out character of geological structures, divide different geological bodies, and distinguish possible orebodies, DDS -3 VLF - EM instrument combined with high prices GPS survey is used. One anomaly of possible orebody had been discovered. The anomaly has 30 -50meters wide, and 200 meters long with discontinuous extension. It is indicated that application of VLF - EM is efficient to realize distributed characters of orebodies and fault structures in the investigation area, and also can provide preliminary basis for nest step research and prospecting works.
