Abstract

The Lujing uranium ore field is one of the four major uranium ore fields in the Zhuguangshan rock mass. The tectonic position of Lujing uranium ore field is located in the South China multiphase composite Orogenic belt formed by the combination of the Huaxia plate and the Yangtze plate, which belongs to the Wugong-Zhuguang fault uplift area of the Cathaysian plate. The article explores the occurrence characteristics of uranium minerals and the genesis of uranium ore in the deposit by collecting samples from the Lujing uranium ore field, observing and identifying them under an electron microscope, and analyzing and testing them with an electron probe. The uranium minerals in the Lujing uranium deposit are mainly uranite, pitchblende and uranium thorite, all in the form of independent uranium minerals. In addition, a small amount of uranium exists in the form of isomorphism in thorite, Rutile, zircon, Xenotime and other accessory minerals. Uranium ore and pitchblende are the main uranium bearing minerals in the study area. The uranium ore mineral assemblage is mainly composed of four types: uranium ore metal sulfide, uranium ore fluorite, pitchblende uranium ore Pyrite, and uranium ore quartz. The characteristics of the paragenetic assemblage of uranium ore and other minerals reflect that the temperature of uranium mineralization is at the middle low temperature mineralization stage. Uranium ore is mostly formed and reduced in the environment, and the formation age of uranium ore is generally later than that of Pyrite. The main genesis of uranium ore is the transformation of primary uranium ore into pitchblende, which is then converted into uranium ore again through a reducing environment. Uranium in uranium bearing minerals is reactivated to form uranium ore.
