| 摘 要： | 含矿含 水层中的碳酸盐对砂岩型铀矿床的地浸开采影响;较大，根据岩矿鉴定结果及化学分析资料，结合野外岩、矿心编录，对738矿岩型铀矿床含矿含水层中的碳酸盐产出特征及成因机制进行了研究。认为含矿含水层中的致密钙质胶结层是成岩阶段的产物；碳酸盐的溶解迁移和沉淀析出是氧化－还原作用引起酸碱平衡破坏的结果。分析了不同存在形式的碳酸盐对地浸工艺的影响。

| Abstract: | The carbonate of host bed aquifer has great influence on sandstone type uranium deposit of in-situ leaching. On the basis of petrological determination in addition rock and mineral logging, the carbonate distribution feature and mechanism of formation is researched in host bed aquifer in No.738 sandstone type uranium deposit. The compact carbonated cementecl sand is thought to be product on diagenetic phase. The dissolving-migration and precipictaion_sparation out result from destraying of acid and ackaline balance caused by redox. The effect of various forms of carbonate on sandstone type uranium deposit of in-situ leaching is analysed. |
