REE geochemical characteristics of high-alumina partings,from Taiyuan Formation of Carboniferous in Jungar Coalfield,were studied by using ICP-MS.The results show that the REE contents range from 2.63 to 345.56μg / g,and the average 61.83μg / g.The ratios of LREE / HREE range from 0.56 to 25.64,and the average 5.56.These characteristics show that LREE are much richer than HREE.REE distribution patterns of samples are characterized by obvious negative Eu anomaly.REE is not obviously effected by diagenesis of the high-alumina partings according to the bad relativity between δCe and δEu,( Dy / Sm) N,ΣREE,respectively.According to the characteristics of δCe and Ce_anomvalues,it can be concluded that the sedimentary environment of high-alumina partings is mainly continental oxidized water conditions.The characteristics of REE show that the material source of high-alumina partings are from Yinshan ancient continent,and its provenance are mainly Caledonian-Hercynian granites,such as plagioclase granites,adamellites,moyites and aplitic granites,and bauxite deposits from Benxi Formation.
