Abstract: Chloroform bitumen A has been extracted from coal and coal gangue in southeastern margin of Ordos basin. The trace elements and rare earth elements in it are tested and analyzed, which provide some geochemical information for revealing the geochemical characteristics of coal in this area. The study suggests that the original materials for forming coal in southeastern margin of Ordos basin are most likely from the upper crust.

Key words: Ordos basin, coal, bitumen, trace element, rare earth element
