花岗岩型铀矿床是我国最重要的铀矿资源产出类型,铀矿体以热液脉的形式赋存在花岗岩体中。华南花岗岩众多,但花岗岩型铀矿床仅集中产出在为数并不多的几个花岗岩体中,这些含铀矿体的花岗岩一般被称为产铀花岗岩。产铀花岗岩往往含有非常高的铀含量(>10×10-6),并且铀浸出率很高,能为后期热液矿化提供铀源。对华南这些具有成矿专属性的产铀花岗岩,其岩石成因以及铀在花岗岩中的富集机制受到人们的关注。寻找同类型的产铀花岗岩对于在华南进一步寻找花岗岩型铀矿床具有 Granite-type uranium deposit is the most important type of uranium resources in China. Uranium ore bodies are deposited in the granite body in the form of hydrothermal veins. There are many granites in South China. However, granite-type uranium deposits are concentrated in only a few granite bodies. These granites containing uranium ore bodies are generally called uranium-bearing granites. Uranium-bearing granites often contain very high levels of uranium (> 10 × 10-6) and have high rates of uranium leaching, providing uranium for later hydrothermal mineralization. In South China, these ore-bearing uranium granites with special metallogenic properties have received much attention due to their rock genesis and enrichment mechanism of uranium in granite.
