摘要
This paper reports data of yttrium and rare earth(REY,or REE if Y is considered)in a Ge-poor(the average value of Ge is 0.57 μg/g)coal from the Wulantuga ore deposit,middle Inner Mongolia,northern China.The contents of yttrium and rare earth in six coal samples of the Wulantuga ore deposit were detected by inductively coupled plasma mass spectrometry.The content of yttrium and rare earth in the study area varies from 5.88 to 119.19 μg/g,with an average of 61.85 μg/g,similar to the average value for world coals.The light-REY and heavy-REY enrichments are the two major REY-enrichment types of the Ge-poor coal from the Wulantuga ore deposit,and the top and bottom parts of the coal seam have a higher content of REY than the middle part.The sources of yttrium and rare earth in the Ge-poor coal of Wulantuga may be mainly associated with terrigenous materials and natural waters enriched in yttrium and rare earth.
