Abstract

Based on petrographic research, organic geochemistry and elemental geochemistry are applied to analyze the sedimentary environment of the Ordovician Wulalike Formation in the Ordos Basin, and explore its impact on organic matter enrichment. The research results indicate that the shale of the Wulalike Formation is mainly composed of quartz and clay minerals, and there is a certain degree of positive correlation between the accumulation of organic matter and the content of quartz and clay minerals. The content of quartz and clay minerals has a positive promoting effect on the accumulation of organic matter in the Wulalike Formation. The sedimentary environment is a reducing environment with weak water stratification, and during the sedimentation period, the water is relatively deep and stable. There is a certain positive correlation between organic matter accumulation and redox conditions in the study area, but a poor correlation with ancient water depth and climate indicators, indicating that the reducing environment may be the influencing factor of organic matter accumulation. In contrast, the warm and humid climate has little effect on improving the paleo-productivity of the Wulalike Formation.
