土壤天然热释光测量在可地浸砂岩型铀矿找矿中的应用研究

Application research on soil natural thermoluminescence survey in prospecting for in-situ leachable sandstone-type uranium deposit

土壤天然热释光测量是基于土壤矿物晶体能够累积天然辐射场的原理 ,通过取样测量土壤样品热释光强度进行找矿的方法。在扎吉斯坦铀矿床上进行的应用研究结果表明 ,该方法是经济而有效的 ;在可地浸砂岩型铀矿床头部和尾部形成了清晰的土壤热释光高值异常 。

Soil natural thermoluminescence survey is a prospecting method the principle of which is based on the capability of soil mineral and crystal to accumulate natural radiation.By surveying the thermoluminescence intensity of soil samples the location of deep-buried uranium ore-body might be delineated.The application research of the above method in Zajistan uranium deposit shows that the method is both economic and effective.Clear and high value thermoluminescence anomalies appear at the location of the head and the wing of the uranium roll.
