Revisiting the late Permian coal from the Huayingshan, Sichuan, southwestern China: Enrichment and occurrence modes of minerals and trace elements

The Late Permian coals from the Huayingshan Coalfield of southwestern China are significantly enriched in Zr (695μg/g), Nb (75.9μg/g), Se (6.99μg/g), Hf (10.1μg/g), and rare earth elements and Y (1423μg/g). Previous studies showed that the sediment-source region for these coals was the Kangdian Upla...
