| Abstract: | Jiyang depression,one of the most important oil-bearing basins in eastern China,has been studied with the theory and method of molecular stratigraphy.Eocene was the main period of the basin formation.The results suggest that molecular stratigraphy is helpful to determine the source of the amorphous solid organic matter which is widely dispersed in lacustrine source rocks,open out the existence and types of the microbe in paleoenviroment rebuilding,finely distinguish the organic facies,and build and consummate the sequence stratigraphy framework.Molecular stratigraphy provides a new important stratigraphical technique in petroleum geology,which may be especially valuable where methods based on paleontology failed. |
