REE/trace element characteristics of sandstone-type uranium deposits in the Ordos Basin [PDF]
Chinese Journal of Geochemistry, 2006 The major elements, trace elements and REEs were analyzed on the samples collected from the sandstone-type uranium deposits in the Ordos Basin to constrain the mechanism of uranium enrichment. The total REE amount ranges from 36.7 to 701.8 μg/g and the REE distribution patterns of the sandstone-type uranium samples are characterized by LREE enrichment ...
