摘要
湘西震旦—寒武系页岩与沉积改造型铀矿床有关。页岩中的粘土矿物主要为水云母,次为高岭石、多水高岭石、蒙脱石,少量水铝英石。层状变质矿物为绢云母、绿泥石、斜绿泥石、滑石。采用多种方法对这些矿物作了分析,认为水云母是赋铀的重要载体矿物。
The reformated-sedimentary type uranium deposit is related to Sinian-Cambrian shale in western Hunan. The clay minerals in shale are mainly hydromica, next to it is kaolinite, halloysite, montomorillonite and little allophane. The phyllo-metamorphic minerals are sericite,chlorite,clinochlore and talc. Many methods are adopted to analyse above minerals, and hydromica is considered to be the important uranium-bearing mineral.
