Abstract: Stone coal is a special resource, because it is associated with a variety of raremetal elements. The elemental geochemical characteristics of stone coal canprovide useful information for the study of its formation and evolution history.The content of rare earth elements in stone coal has been the focus ofattention. Stone coal is widely distributed in southern Shaanxi province ofChina. In order to study the content and distribution of rare earth elementsin stone coal, and provide a plan for the comprehensive development and utilizationof stone coal, this study tested the rare earth elements content ofstone coal, parting and coal ash samples, respectively, compared the contentof rare earth elements in stone coal, parting, coal ash with the mean value ofChina coal, the mean value of world coal and the abundance value of uppercrust, and discussed the features of rare earth elements content in differenttypes of samples in southern Shaanxi province of China. The average contentsof rare earth elements in the samples of stone coal, parting and coal ash werecalculated, and the enrichment coefficients of the samples with the mean valueof China coal, the mean value of world coal and the abundance value ofupper crust were listed. The distribution rules and characteristics of the contentsof rare earth elements in different types of samples in southern Shaanxiprovince of China were summarized.
