便携式X射线荧光(field portable X-ray fluorescence,FPXRF)仪具有仪器轻便、分析速度快、成本低的特点,在野外矿产资源勘查中得到了广泛应用。利用FPXRF仪对某成矿区的浅钻岩芯进行现场快速分析,获取了Ti、Mn、Fe、Cu、Zn等元素含量随深度的变化信息,并圈出了一处Cu异常区。应用结果表明,相对于传统化探取样方法而言,该方法大大减少了工作量,提高了工作效率,节约了分析成本,优势较为明显。
The portable X-ray fluorescence (FPXRF) instrument has the characteristics of light weight, fast analysis and low cost. It has been widely used in the field exploration of mineral resources. The FPXRF was used to analyze the shallow core of core in a metallogenic area by on-site analysis. The information about the variation of Ti, Mn, Fe, Cu, Zn and other elements with the depth was obtained and a Cu anomaly area was excavated. The application results show that compared with the traditional geochemical sampling method, the method greatly reduces the workload, improves the work efficiency, saves the analysis cost, and has obvious advantages.
