摘要
土壤离子电导率测量是隐伏金属矿床、贵金属矿床普查找矿的重要技术方法,本研究应用该方法对隐伏可地浸砂岩铀矿进行普查找矿实验研究。实验表明,本区土壤离子电导率背景值为22.91μs/cm,异常平均值为513.96μs/cm,最高异常值达1349.30μs/cm。它可以圈定舌状蚀变砂岩体与未蚀变砂岩的接触边界,从而可以圈定隐伏砂岩铀矿的产出位置,是隐伏可地浸砂岩铀矿普查找矿的既经济又有效的方法。
Soil ionic conductivity survey is an important method prospecting for the concealed metallic and precious deposit. This method has been used to study and prospect for a concealed leachable sandstone uranium deposit in this paper. The result about the soil ionic conductivity in studied area shows that the background, average and highest anomalous values are 22.91, 513.96 and 1349.30μs/cm respectively. According to the result, the contact boundary between lingulate altered and unaltered sandstones can be contoured, thus, the occurring position of a concealed sandstone uranium deposit can be blocked out. Consequently, this method is economical and effective to prospect for concealed leachable sandstone uranium deposits.
