摘　　要：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。The geo-electrochemical method is a new technology in search for deep concealed deposits.With an electrical field,active metal ions move into special receivers.Electrolyte in the receiver is analyzed.Metal ion anomalies which may be related to concealed ore deposits can guide prospecting.Geo-electrochemical extraction method,soil ionic conductivity method and soil heat-released mercury method were applied to the prospecting for uranium deposits,which are located in the Huxi ore district in Jiangxi Province of China and the Four Mile East mine in Australia.Combined with different geological backgrounds and geo-chemical features,the authors studied practical application effect of the integrated technology,and put forward an ideal geo-electrochemical anomaly pattern of the hydrothermal uranium ore vein.The result shows that the application range of the method is suitable not only for volcanic type uranium deposits but also for sandstone-type uranium deposits.The prospecting result is satisfactory.
