摘要
The portable X-ray fluorescence analyzer was used to investigate the concealed ore body over the shallow Quaternary cover- age area of the Shuitou fluorite ore district in Linxi County, Chifeng City. Based on an analysis of the data collected and a comparison with the known ore body, the authors have drawn the conclusion that the portable X-ray fluorescence analyzer is serviceable and can provide evidence for the prospecting of concealed fluorite ore deposits.
