With the advancement of microscopic technology,the research on microscopic uranium miner-als and fine uranium mineralogy has gained increasing importance in uranium geology.This paper intro-duces five planar phases microscopic uranium mineral identification methods,encompassing polarizing mi-croscope identification,radiography method,α track etching,scanning electron microscope+electron probe method,and X-ray fluorescence semi-quantitative analysis,along with the automatic integrated min-eral analyzer analysis.For a detailed and insightful study of microscopic uranium minerals,these five methods can be employed simultaneously,interactively,or individually in the identification and analysis of microscopic uranium minerals.Polarizing microscopy stands out as the most basic and essential method for identifying microscopic uranium minerals.XRF semi-quantitative analysis aids researchers in determining whether uranium minerals are present in optical slices.Radiography and a-track etching enable the mastery of the distribution of uranium minerals in the entire optical slices and serve as auxiliary tools for polarizing microscopy and scanning electron microscopy in identifying uranium minerals.Additionally,they provide a clear target for in-situ micro-analysis under the electron microscope.Scanning electron microscope(SEM)and electron probe microanalysis(EPMA)contribute to an elaborate study of microscopic uranium miner-als,and their integration with polarizing microscopy allows for a direct examination of these minerals.The automatic integrated mineral analysis system,when combined with other methods,offers a comprehensive and intuitive understanding of uranium minerals across the entire optical sheet.The synergistic and com-prehensive application of these five methods significantly enhances the efficiency and precision of identif-ying microscopic uranium minerals,elevates the study of microscopic uranium minerals to a new level,and injects new vitality into the conventional discipline of micromineralogy.
