摘要：

In this article, 15 coal samples from South China have been systematically analyzed. Combining the geological features of coal seam and wall rocks,especially the distribution of hydrothermal veins and thermally metamorphosed minerals, the rare earth element distribution patterns of unmetamorphosed, low-grade-metamorphosed, regional-metamorphosed,thermal-contact metamorphosed and hyd rothermally-metamorphosed coals tell us that REE in the regional-metamorphosed, thermal-contact metamorphosed and hydrothermally-metamorphosed coals have been mobilized and fractionated to varying degrees. All these reseaches will become judging evidences for coal geochemistry.
