摘要
随着现场X荧光元素分析技术的发展,便携式X荧光元素分析仪在野外矿产勘查工作中崭露头角。以内蒙古乌力吉敖包浅覆盖区的萤石矿为基础,开展现场X荧光勘查验证工作,通过元素异常分析和矿区实际情况对比得出以下结论:(1)便携式X荧光元素分析仪在浅层覆盖区勘查中具有较高的效率与精度;(2)连续的Ca元素异常对萤石矿脉具有良好的指示作用;(3)化探方法存在一定多解现象,但根据矿床类型并结合其他勘查方法可排除多解区域。
With the development of field X fluorescence analyzing technology,portable X-ray fluorescence analyzer performed well in field prospecting.In this paper,the fluorite mine in the coverage area of Wuliji'aobao in Inner Mongolia is taken as an example to carry out X-ray fluorescence survey.The following conclusions are drawn through the analysis of diagram element anomaly and comparing the actual situation of ore area.(1)Portable X-ray fluorescence analyzer has high efficiency and accuracy in exploration of shallow coverage area.(2)Continuous anomalies of Ca element have good indications for fluorite veins.(3)Geochemical exploration methods have multiple solutions,but multiple solutions can be ruled out according to the type of ore deposits and other exploration methods.
