X-ray fluorescence (XRF) measurements on mumiyo deposit PRM10 (profile B) from Petermann Range@en

High-resolution line-scan images were recorded and XRF analysis was carried out with an ITRAX XRF core scanner (Cox Analytical Systems, Sweden). XRF analyses were conducted with a chromium X-ray tube (settings 30 kV and 55 mA), an exposure time of 20 seconds, and a resolution of 500 µm.本研究采集并存储了高分辨率线扫图像，并借助瑞典考克斯分析系统（Cox Analytical Systems）生产的ITRAX型X射线荧光光谱（X-ray Fluorescence，XRF）岩心扫描仪开展XRF分析。本次分析采用铬靶X射线管，设置参数为管电压30 kV、管电流55 mA，曝光时长20秒，分辨率达500微米。
