地球电化学法是一种借外加电场使活动态的金属离子定向迁移到特制的接收装置、分析装置中的电解物,从而发现与隐伏矿床有关的金属离子异常,达到找矿目的的新方法。通过在中国江西省乐安县湖溪某矿区、澳大利亚Four Mile East某矿区开展以地球电化学提取测量为主、土壤离子电导率测量为辅寻找隐伏铀矿的工作,结合相应矿区地质、地球化学特征对该集成技术的应用效果进行了对比研究,提出了地球电化学法寻找隐伏铀矿的理想异常模式。结果表明,地球电化学法不仅适用于厚层覆盖区寻找火山岩型铀矿,对砂岩型铀矿同样可以取得良好的找矿效果。
Earth’s electrochemical method is a new method to find the purpose of ore-prospecting by orienting the movable metal ions to a special receiving device by applying an electric field and analyzing the electrolytes in the device to find the metal ions anomalies related to the hidden deposits. By carrying out the work of earth electrochemical extraction measurement and soil ion conductivity measurement to find concealed uranium deposits in a certain mining area of Lake Creek in Le’an County, Jiangxi Province, China, and in a mining area of Four Mile East in Australia, combining the geological and geochemical characteristics of the corresponding mining areas The application effect of the integrated technology is compared and the ideal anomaly mode of finding the hidden uranium deposit by the earth electrochemical method is proposed. The results show that the electrochemical method is not only suitable for looking for volcanic uranium deposits in thick overburden areas, but also good prospecting results for sandstone-type uranium deposits.
