| 中文摘要: |
| 芨岭矿床位于龙首山中部华北板块阿拉善地块西南缘，其主要铀矿化类型为钠交代花岗岩型。本文介绍 了矿床的主要含矿岩石特征，通过对矿床内钻孔采取的化学分析样品进行铀镭系数的统计及特征研究， 基本了解了该矿床的铀镭平衡系数分布情况、随深度变化关系以及铀镭含量对平衡系数的影响，对区内 伽马测井数据修正及矿体储量计算提供了一定依据。 |
| 英文摘要: |
| The Jiling deposit is located on the southwestern margin of the Alxa block of the North China Platein the central part of Longshou Mountain. Its main type of uranium mineralization is the sodium metasomaticgranite type. This paper introduces the main characteristics of the ore-bearing rocks in the deposit. By conducting statistical analysis and characteristic studies on the uranium-radium coefficients of chemical analysis samples taken from boreholes within the deposit，we have gained a basic understanding of the distribution of uranium-radium equilibrium coefficients，their relationship with depth，and the impact of uranium and radium content on theequilibrium coefficient. This provides a certain basis for the correction of gamma logging data and the calculation ofore reserves in the area. |
