摘　　要：大地气态水是大地土壤的重要组分,借助于地球碳循环向上迁移的铀离子流积聚于大地土壤层,在松散的大地土壤空气中形成地球化学异常。铀离子流与下伏赋存的矿体相呼应,因此设法采集近大地土壤空气中离子流转化为新形成的固定相之前的组分并分析测试之,从而发现隐伏的深埋铀矿体。该方法已在内蒙某地浸砂岩铀矿床上进行的两年初步试验工作(包括剖面性测量与面积性测量),结果表明,异常幅度明显高于常规铀金属量测量方法,地球化学异常衬度也大大好于常规铀金属量测量方法。该项技术在油气矿藏的勘查及其他金属矿产资源的勘查中也有重要的应用潜力。Earth gaseous state water is a important component of ground soil. The uranium ions gathered at soil layer with the aid of earth carbon circulation and upward migration, forming geochemical abnormity in loosened ground soil air. These uranium ions with ground ore-body contract finely with each other. So We are trying to find a method to collected ions flow in near soil air which the component before it is new forming fix phases , then be analysis these uranium ions, thereby, and find out the hidden uranium ore-body. This technique has been preliminary testing in the Neimengu a certain ISL-sandstone type uranium deposit （include section survey and area survey）, the results show , the width of abnormity of earth gaseous state water uranium survey is larger than conventional uranium metal content survey, the contrast of abnormity of earth gaseous state water uranium survey is larger than conventional uranium metal content survey too. this technique for oil and gas resources exploration and for other metal minerals resources exploration has an important application potentiality.
