电法在金属矿产物探工作中一直占有重要地位,随着找矿工作进一步深入,地表矿石日益减少,在这种情况下,寻找深部的隐伏矿就是今后找矿的主要目标。瞬变电磁法具有探测深度大、横向分辨率高的特点。与常规的电法比较具有探测深度深,能轻易穿透低阻覆盖层,分辨率高及受旁侧地质体影响小的特点。本次采用了大定源回线方法对某矿区中深层矿体进行探测并对得到的数据进行处理以及部分异常解释。
The electric method has always occupied an important position in the geophysical prospecting of metal minerals. With the further deepening of the prospecting work, the surface ore is decreasing day by day. In this case, finding the deep concealed ore is the main objective of prospecting in the future. Transient electromagnetic method has a detection depth, high lateral resolution. Compared with the conventional electrical method, it has the characteristics of deep exploration depth, easy penetration of low resistance overburden, high resolution and little influence from lateral geologic bodies. This time using a large set of source return line method to detect a deep ore body in a mining area and the data processing and some abnormal interpretation.
