| 摘 要： | EH4成像技术是以电磁原理的地球物理测深手段，该方法对地下地质结构的解析度高，有效探测深度适中，能够较为精确探测矿体的规模、产状、埋深等信息。通过对广西某矿山外围深部矿体勘探的实际应用，发现该区外围深部存在明显的地球物理异常，展示了外围具有良好的成矿前景。实践证明EH4技术在老矿山外围深部寻找隐伏矿体取得了良好效果。

| Abstract: | EH4 geophysical system belongs to electromagnetic survey method. EH4 system is the most effective electromagnetic method for metalliferous mineral explorations with high detecting resolution and appropriate depths of penetration. It is frequently effective to investigate the spatial variations, sizes of orebodies, depths of orebodies in mineralized/alteration zones. The method was used to some mineral which occurrences in Guangxi, and the surveying results of EH4 system measurement show that there is a clear geophysical anomaly in depth of periphery of the deposit. It is indicated that the periphery of deposit has a good metallogenic prospects. The surveying results also indicate that EH4 system was applied in combination in a case study at known deposit in order to find out an extension of ore bodies, which finally turned out an ideal and expected results. |
