摘　　要：本文以下庄铀矿田330花岗岩型铀矿床和新疆511、512砂岩型铀矿床为例,分析对比了这两种类型铀矿床上土壤天然热释光的发光曲线特征,探讨了铀矿床上热释光强度的分布特点。初步研究的结果表明:在花岗岩型铀矿床正上方热释光法测量结果有高值异常,而在无矿地段测量值小;在砂岩型铀矿床正上方热释光法测量为低值异常,而在矿体的周围出现高值异常。Taking uranium deposits No.511、512 in Yili Basin,Xinjiang Autonomous Region and Xiwang uranium deposit in Xiazhuang Ore-field,Guangdong province as examples for sandstone type and granite type uranium deposits the glowing curve characteristics and the intensity distribution features of soil-natural themoluminescence are analysed,compared and discussed.The results indicate that there is a high value anomaly of soil-natural themoluminscence above the uranium ore deposit and a low value one above the non-ore area at granite type uranium deposit.On the contrary,there appears a low value anomaly of soil-natural thermoluminescence above the uranium ore deposit and a high value anomaly above the non-ore area at sandstone type uranium deposit.
