摘要
Eocene sedimentary evolution and its control over development of coal and oil shale in Fushun coalfield were investigated through out-crop measurement,deposit character analysis,facies reconstruction,as well as pollen assemble and geochemistry data comparison.The results indicate that the sedimentary evolution started from fan delta and swamp facies associations of the Guchengzi Formation,then underwent shallow lake and semi-profundal to profundal facies associations of Jijuntun Formation,eventually evoluted into cycle deposit of the Xilutian Formation. Sedimentary environment changes of coal and oil shale cause variation of organic origin and water condition,resulting in “hydrogen-enrichment” and increasing hydrocarbon potential of coal deposit associated with oil shale in Fushun coalfield.
