Abstract:In Changpai uranium exploration area of Guangdong Province, the authors obtained content data of more than ten kinds of elements in soils, such as Cu, Pb, Zn, As and Sr, by means of X-ray fluorescence rapid measurement of the soil samples. According to the resultant diagram based on the measurement results, the indicative function of these elements for the concealed granite-type uranium deposit is discussed is this paper. The results show that the anomaly of the concealed granite-type uranium deposit can be found by using the portable X fluorescence spectrometer for soil sample survey.
