Seven mudstone/shale core samples were collected from the first member of the Shahejie Formation (E2s1) in this study, which is considered as a potential source rock in the Liaodong Bay subbasin. The biological sources and sedimentary environments of the E2s1 source rocks were studied based on the a...
