X-ray fluorescence (XRF) measurements on mumiyo deposit DallSW1830 (profile A) from Dallmann Berge@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.本研究采集了高分辨率线扫描图像，并借助瑞典考克斯分析系统（Cox Analytical Systems）的ITRAX XRF岩心扫描仪开展X射线荧光（X-ray Fluorescence, XRF）分析。本次分析采用铬靶X射线管，工作参数设置为30 kV与55 mA，曝光时长20秒，空间分辨率达500 µm。
