摘　　要：自20世纪以来,X射线荧光光谱分析在地质、环境、材料和冶金等诸多领域已经得到了广泛运用。随着IODP等大洋钻探计划的实施,能够进行定量、快速、高分辨率分析的船载系列XRF岩心扫描应运而生。XRF岩心扫描法的优势在于快速、无损、连续测试,对样品制备要求低以及扫描结果的分辨率高。详尽介绍了XRF岩心扫描法的基本原理、测试方法及扫描效果影响因素,并分析了部分影响因素的解决方法,同时结合常见的第四纪沉积物,如海洋沉积物、湖泊沉积物、黄土、石笋和珊瑚等,就主要的元素及元素比率指标等所代指的环境意义进行了讨论,揭示了XRF岩心扫描仪在第四纪沉积物研究中的应用与发展前景。X-Ray Fluorescence analysis method has been widely applied in geology, environmental sci- ences, material sciences and metallurgy since last century. The implementation of IODP, that requires quantitative, continuous and high resolution analysis results, has promoted the application of XRF core scanning, which has great advantages in getting fast, non-destructive, continuous and high reso- lution scanning results. This paper introduces the basic theory, scanning method and influence factors of XRF, and also summarizes some resolutions to minimizes the influences. This paper also discusses the environmental significances of some elements and element ratios in Quaternary sediments including marine sediments, lacustrine sediments, loess, stalagmite and coral reefs, representing the application of the XRF core scanner in the future.
