ABSTRACT: Stone coal is a special resource, because it is associated with a variety of rare
metal elements. The elemental geochemical characteristics of stone coal can
provide useful information for the study of its formation and evolution history.
The content of rare earth elements in stone coal has been the focus of
attention. Stone coal is widely distributed in southern Shaanxi province of
China. In order to study the content and distribution of rare earth elements
in stone coal, and provide a plan for the comprehensive development and utilization
of stone coal, this study tested the rare earth elements content of
stone coal, parting and coal ash samples, respectively, compared the content
of rare earth elements in stone coal, parting, coal ash with the mean value of
China coal, the mean value of world coal and the abundance value of upper
crust, and discussed the features of rare earth elements content in different
types of samples in southern Shaanxi province of China. The average contents
of rare earth elements in the samples of stone coal, parting and coal ash were
calculated, and the enrichment coefficients of the samples with the mean value
of China coal, the mean value of world coal and the abundance value of
upper crust were listed. The distribution rules and characteristics of the contents
of rare earth elements in different types of samples in southern Shaanxi
province of China were summarized.
