携带式同位素放射性X—射线荧光分析,是一种非破坏性(对样品)的仪器分析方法。笔者在某地区地质普查中使用重庆地质仪器厂制造的HYX—1型X射线荧光仪,对原生露头、次生晕土壤、中强异常检查、槽探和钻孔岩心等工程中的花岗岩、灰岩、砂岩和矽卡岩等不同岩性进行了室内粉样和现场测锡工作,获得了与化学分析和光谱分析较一致的理想结果。为该地区圈出四个异常范围、发现了新的锡矿化,指导了探矿工程的布置。
Portable isotope radiometric X-ray fluorescence analysis is a non-destructive (sample) instrumental analysis method. The author uses the HYX-1 X-ray fluorescence spectrometer manufactured by Chongqing Geological Instrument Factory in the geological survey of a certain area to study the characteristics of primary outcrop, secondary halo soil, moderate anomaly check, granite and gray Rock, sandstone and skarn and other lithology of indoor powder samples and tin work on the scene, obtained with the chemical analysis and spectral analysis of the ideal results. Four anomalous zones were circled in the area and new tin mineralization was discovered, guiding the layout of prospecting works.
