Major,rare earth and trace elements and mineral composition of the oil shale and the oil shale residue from the Huadian area,Jilin Province were determined by XRD,XFS and ICP-MS methods.The results show that the REE contents in the oil shale is poorer than the average of North Americia shales(NASC).The chondrite-normalized REE patterns show a negative gradient and the average(La/Yb)_N ration of the oil shale is highter than 1,reflecting higher LREE contents.The REE curve normalized by NASC is horizontal and the average(La/Yb)_S ration of the oil shale is close to 1.REE fractionation is not clear.Normalized by chondrites and NASC,remarkable positive Eu anomalies are found.The average contents of trace elements in the oil shale samples,when compared with those in NASC and the average of the earth's crust,are richer in Sb,Nb,Cs,Zn,Bi and W. The contents of both REE and trace elements in the oil shale residue are higher than those in oil shale.
