摘要
蒙其古尔铀矿床为伊犁盆地大型层间氧化带砂岩型铀矿床之一,其矿体的埋深、空间定位和矿石品位等均与512、511等矿床有较明显的差异。本文以X射线衍射和扫描电子显微镜分析测试结果为基础,重点研究了蒙其古尔铀矿床含矿层岩石的黏土矿物总量、黏土矿物类型及含量分布等特征,并与512、511等典型矿床进行相应的对比,探讨了黏土矿物组成对蒙其古尔铀矿床铀沉淀富集的影响作用。
Mengqiguer uranium deposit is one of large interlayer oxidation zone sandstone hosted uranium deposits in the south of Yili basin, the deposit is quite different to depotit 511 and deposit 512 in the ore buried depth, orebody locating and ore minerals. Based on the study of X-ray diffraction and SEM, clay minerals in Mengqiguer uranium deposit were analyzed in their total content, types and distribution feature and campared with those of clay minerals in deposit 512 and 511. The affection of clay minerals on the precipitation and enrichment of uranium was discussed in the formation of Mengqiguer uranium deposit.
