摘要
随着新一轮地质找矿的进行,地表易识别矿越来越少,找矿难度不断增大,寻找隐伏矿床成为地质工作所面临的紧迫课题,充分发挥地球物理方法在地质找矿中的作用将显得越来越重要。激发极化法是一种极其有效的勘查手段,能快速圈定异常,确定找矿靶区,而EH-4是一种快速的电阻率测深方法,能完成剖面和测深双重功能,可以精确地探测矿体的三维形态、规模、产状变化和细部结构。激电和EH-4两者结合应用能充分发挥两者的优点,达到更好的找矿效果。
Along with the gradual exploration of geological mine work, mine on the surface which is easy to identify is fewer and fewer, so it is difficult to prospect the mine. The search of potential mine is an urgent task, therefore, geophysical method plays an important role in prospecting mine. IP is a very effective exploration method, which can quickly locate abnormality and determine the target area, while EH-4 is a quick resistivity sounding method, which can survey the profile and depth. What＇s more, it can accurately detect the three- dimensional shape, scale, occurrence change and structural details. The combination of IP and EH-4 can give full play to their advantages and achieve better prospecting effect.
