Analysis on the characteristics of radioactive hydrogeology in the Longshoushan metallogenic belt of Gansu Province

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 Ca²⁺ 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.
