摘      要：Yttrium(Y)is a critical metallic element that is used widely in modern scientific,technological,and industrial *** in the Zhijin area of Guizhou Province,China,are famous for Y enrichment,but the enrichment characteristics and sources remain *** studies suggested that the sources of rare earth elements(REEs,La-Lu)and Y(REYs,La-Lu+Y)were related to hydrothermal ***,this study presents evidence refuting that hypothesis,with major and trace elemental data collected with quadrupoleinductively coupled plasma-mass spectrometry(Q-ICPMS)*** data show that Y in Zhijin REYscontaining phosphorites has a normal distribution and is particularly enriched relative to other *** Y enrichment degree is different at different∑REY ***,the Y enrichment degree is higher at lower∑REY values and lower at higher∑REY *** REYs-containing phosphorites show features of primary *** REEs and Y have good correlations with P2 O5 in the phosphorites with low REYs contents(total REYs535 ppm),REEs have a good correlation with P2 O5 but Y does *** enrichment processes of REYs are suggestive of complex sources of ***,seafloor hydrothermal fluids were not the direct source of *** seawater mixed with terrestrial sources might have contributed to the origin of Y *** study could lead to improvements in Y mineral resource explorations and the situation involving the global REYs supply crisis.
