摘要
龙首山成矿带是我国著名的铀成矿带,在充分收集前人资料的基础上,开展水文地质调查,依据研究区水文地质特征,研究龙首山成矿带水文地质分区和放射性水化学特征,重点对水中各类离子、放射性元素含量及其相互关系,以及放射性水异常点的分布规律进行分析研究。以芨岭钠交代型铀矿床为例,分析放射性水文地质特征与铀矿化之间的关系,发现了地下水中Na^+和Ca^(2+)含量所呈的负相关关系与铀成矿过程中的去硅去钙富钠作用相一致,串珠状分布的地表水点与深部构造的走向一致,串珠状分布的放射性水异常点与深部控矿构造和铀矿化的走向一致的特点。将放射性水文地质特征与热液铀成矿理论相结合,对深部铀矿地质找矿工作具有一定的指导和帮助。
The Longshoushan area is famous uranium metallogenic belt in China.Based on previous data and characteristics of hydrogeology,the relation between various ions and content of radioactive elements and the distribution law of radiohydrological anomalous was analyzed.Taking Jilin uranium deposite for example,the relationship between radioactive hydrogeology and uranium mineralization is analyzed.It is found that the negative correlation between Na+and Ca 2+was consistent with the low-Si,-Ca and rich in sodium,the moniliform distribution of surface water points was consistent with the strike of deep structures and the moniliform distribution of radiohydrological anomalous was consistent with the strike of controlling structures and uranium mineralization.Finally,the combination of characteristics of radioactive hydrogeology and hydrothermal metallogenic theory of uranium could have guidance significance for deep-prospecting of uranium deposit.
