放射性伽玛测井在柴达木东北缘查查香卡地区稀有金属和稀土元素研究中的应用

Application of radioactive gamma logging in the study of rare metal elements and rare earth elements in Chachaxiangka area,northeastern margin of Qaidam

随着中国经济的快速发展,对矿产资源的需求量日益增加,特别是稀土元素中的稀有金属是具有战略意义的金属元素。稀有金属广泛地应用于航天、航空、电子、核电等高科技领域。本次勘查主要是对查查香卡地区324铀矿点落实控制,并提交资源量。勘查中发现铀矿床岩石中放射性元素铀(U),钍(Th),钾(K)和密切相关,实验室样品分析结果也显示查查香卡铀矿床中的稀土矿与铀矿的关系密切。根据铀矿勘查结果,铀矿含量达到硬岩铀矿工业品位,同时预测查查香卡地区铀矿伴生稀土原生矿石达到边界品位,并通过FORECAST函数推算出稀土元素(∑REE)的含量。

With the rapid development of China’s economy,the demand for mineral resources is increasing day by day,especially rare metals and strategic metals in rare earth elements. Raremetals widely used in aerospace,aviation,electronics,nuclear power and other high-tech fields. The main purpose of this exploration is to control 324 uranium deposits in Chachaxiangka area and submit the amount of resources.It is found that the radioactive elements U,Th and K in the rocks of the Chachaxiangka uranium deposit are closely related to the rare elements in rare earth elements. The results of laboratory sample analysis also show that the rare earth deposits in Chachaxiangka uranium deposit are closely related to uranium deposits.According to the results of uranium exploration,the content of uranium ore reaches the industrial grade of hard rock uranium ore,and the primary ore of Rare Earth associated with uranium ore in Chachaxiangka area is predicted to reach the boundary grade.The content of rare earth elements( REE) was calculated by FORECAST function.
