Utilizing comprehensive ways of outcrops,core and thin section observation,rock mineral composition, organic geochemistry and industrial analysis,the metallogenic characteristics of the coal and oil shale in the upper coal-bearing strata of the Meihe Formation in the Meihe Basin are deeply analyzed. Research shows that the oil shale has lower volatile and organic carbon content and higher ash content than coal. The oil shale overlying the coal layer has higher organic carbon and volatile content and less ash content than oil shale underlying the coal layer. Generally the organic type of oil shale is type ��-��₂,of which,for oil shale underlying coal layer,it is type��,and for oil shale overlying coal layer,it is type ��₁-��₂. The organic matter type of coal is type ��₂-��. As the upper coal bearing strata of the Meihe Formation was developed in the shrinking stage of Meihe Basin,the coal-and oil shale-bearing layers was mainly developed in a fan-delta front-shallow lacustrine-swamp sedimentary environment. Metallogenic sequence of coal and oil shale was mainly formed in the shallow lacustrine environment,which is closely related to the swamp. The main controlling factors on the origin of oil shale and coal depend on the water level in shallow lacustrine stage and ground water table of the swamp stage.
