| 摘 要： | The studies uranium deposit occurs in a geothermally abnormal area. It has the following four features: 1. Uranium mineralization is observed in a certain temperature zone. 2. The uranium deposit occurs in an area characterized by relatively low but highly varying radioactivity in a regionally high radioactive field. 3. Uranium closely coexists with cubic pyrite of hot water origin. 4. Pitchblende is characteristic of hot water origin. This paper focuses on the relationship between ground hot waters and uranium mineralization. Uranium in the deposit is considered to have come from the host rocks, The possible explanation of the formation of this uranium deposit is that uranium was first leached out of the host rocks by ground hot waters and then transported to where uranium enrichment and deposition were favoured, forming uranium deposit under certain conditions. Based on this explanation, this uranium deposit is believed to be the product of hot water activity in the regionally geothermal abnormal zone.
