Abstract The deep-water fine-grained deposits can be not only the source rock,but also the reservoir of unconventional oil and gas. Combined with high-precision centimeter-scale core observation,thin section identification,X-ray diffraction whole rock analysis,trace element test and scanning electron microscopy(SEM)analysis,the laminae characteristics and the genesis mechanism of semi-deep to deep lake fine-grained sedimentary rocks in the Member 2 of the Funing Formation are investigated in the Gaoyou and Jinhu sags of the Subei Basin. The results show that the semi-deep and deep lake fine-grained sedimentary rocks of the Member 2 of the Funing Formation in the Gaoyou and Jinhu sags are complex in lithology,and the laminae with different colors are formed by the mixture and superposition of various material components. The horizontal bedding developed in the fine-grained sedimentary rocks can be further divided into thin-laminated and thick-laminated sedimentary structures,whose macroscopic,microscopic characteristics and the composition are different. The complex forming mechanism of laminae includes two aspects: Formation process and preservation process. The generation(or the input)and the precipitation of each component have seasonal significance during the formation of laminae,whereas the preservation of the laminae could be mainly related to the water depth in the study area.
