摘　　要：文章介绍了活化金属离子法元素垂向迁移机理、异常形成机制、偏提取分析方法及成功实例。该方法认为地下深部矿体释放出活化金属离子并垂向穿过覆盖物而到达地表,使用某种强配位体提取液可以提取这些金属活化离子,其反映的异常较准确地位于矿体垂直上方,并且穿透深度大、信噪比好,已取得了多个成功实例。It is introduced that processes for the vertical migration of elements, the formation of geochemical soil anomalies, lig- and - based soil extract technique and case study. The metal ions which come from mineralized bodies travel upward to unconsolidated surface materials, and can be able to measure using ligand -based soil extractions and ultra sensitive instrumentation. The MMI anom- alies tend to occur directly above buried primary mineralization, deeply buried mineralisation is detectable and background values are low. The MMI technology has already made numerous successes.
