摘要
随着显微技术的发展和铀矿地质工作的日益深入,显微铀矿物、精细铀矿物学的研究越来越重要。本次研究介绍了5种基于平面物相的显微铀矿物鉴定方法,分别为偏光显微镜鉴定法、放射性照相法、α径迹蚀刻法、扫描电镜+电子探针法、X射线荧光半定量分析法、自动综合矿物分析仪分析法,且这5种方法可以相互连用、相辅相成的鉴定显微铀矿物,从而达到精细、直观的研究显微铀矿物的目的。XRF半定量分析法可帮助鉴定工作者提前了解光薄片中是否含铀矿物,偏光显微镜法鉴定显微铀矿物最基本且必不可少的方法,放射性照相和α径迹蚀刻法能掌握整个光薄片中的铀矿物分布状况、辅助偏光显微镜和扫描电镜鉴定铀矿物,并且为电镜下的原位微区分析提供明确的目标;扫描电镜和电子探针可以做到精细的研究显微铀矿物,与偏光显微镜连用可以直观的研究显微铀矿物;自动综合矿物分析系统结合其他方法可以全面、直观的掌握整个光薄片中的铀矿物。将这五种方法连用、综合应用,可以显著提高显微铀矿物的鉴定效率和水平,并将显微铀矿物的研究推向新的高度。
With the advancement of microscopic technology,the research on microscopic uranium minerals and fine uranium mineralogy has gained increasing importance in uranium geology.This paper introduces five planar phases microscopic uranium mineral identification methods,encompassing polarizing microscope identification,radiography method,αtrack etching,scanning electron microscope+electron probe method,and X-ray fluorescence semi-quantitative analysis,along with the automatic integrated mineral 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 andα-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 minerals,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 comprehensive application of these five methods significantly enhances the efficiency and precision of identifying microscopic uranium minerals,elevates the study of microscopic uranium minerals to a new level,and injects new vitality into the conventional discipline of micromineralogy.
