摘要:
纳岭沟铀矿床是我国近年发现的可地浸砂岩型铀矿床之一，其铀矿体产于中侏罗统直罗组下段辫状河砂体中，受古层间氧化带控制，呈板状。本文通过对纳岭沟铀矿床所取的样品进行镜下分析，对其岩性特征进行镜下阐述，分析矿石的镜下特征，这对以后的找矿有着一定的指示意义。
Nalinggou uranium deposit is one of the in-situ leachable sandstone-type uranium deposits dis-covered recently in China, whose ore bodies are located in the braided river sand of lower segment in Middle Jurassic Zhiluo formation. It is influenced by interlayer oxidation zone and presents plate form. In this paper, the samples from Nalinggou uranium deposit are analyzed under microscope, and the microscopic analysis shows lithologic characteristics, which gives the certain instruction significance of further prospecting.
