Characteristics of Rare Earth Elements Associated with Coal in Lvjiatuo Mine
Through sampling and testing the coal seams and their roof and floor of Lvjiatuo Mine,the contents,geochemical parameters and distribution patterns of rare earth elements(REEs)were analyzed comprehensively,and the geochemical characteristics and sources of REEs in coal in the study area were discussed.The results were as follows:the ∑ REE contents in the study area were much higher than that in the world coal and China coal.The distribution pattern of ∑ REE in different coal seams was basically consistent,LREE was relatively enriched and HREE was relatively depleted.∑ REE in Shanxi Formation coal was higher than that in Taiyuan Formation.∑ REE had a good correlation with terrigenous elements.The main source was terrigenous detrital minerals,which had a weak positive correlation with ash and the occurrence was a combination of organic and inorganic states.
