摘　　要：赤铁矿是热液铀矿床中常见的脉石矿物,与铀成矿作用关系密切,对热液铀矿床成因机制研究具有重要意义。国内外已将赤铁矿多手段剖解研究应用于IOCG矿床和华南姚安金矿的矿床成因研究中,并取得良好反馈。通过大量收集国内外赤铁矿和热液铀矿床研究资料,分析目前热液铀矿床成因机制研究中面临的问题,并总结赤铁矿的研究进展,探讨其应用于热液铀矿床成矿机制研究的可能。赤铁矿地球化学特征在成矿时代、成矿温度、氧逸度及成矿流体来源等方面提供了大量的有效成矿信息。基于此,赤铁矿相关研究成果可应用于热液铀矿床成矿机制研究。Hematite is a common gangue mineral in hydrothermal uranium deposits,which is closely related to uranium mineralization and is of great significance to the study of the genesis mechanism of hydrothermal uranium deposits.The multi-means analysis of hematite has been applied to the study of the genesis of IOCG deposits and Yaoan gold mines in South China at home and abroad,and good feedback has been obtained.In this study,by collecting a large number of research data of hematite and hydrothermal uranium deposits at home and abroad,this study analyzes the problems faced in the current research on the genesis mechanism of hydrothermal uranium deposits,summarizes the research progress of hematite,and explores its application to the study of mineralization mechanism of hydrothermal uranium deposits.Hematite geochemical characteristics provide a large amount of effective mineralization information in terms of mineralization age,mineralization temperature,oxygen fugacity,and source of mineralizing fluid.Based on this,the research results on hematite can be applied to the study of the mineralization mechanism of hydrothermal uranium deposits.
