The study of lithofacies identification and its distribution characterizations of shales is essential for the geological evaluation of shale oil exploration and development. In this study, core descri
The paleoenvironment determines OM enrichment and preservation, and thus contributes to the different TOC contents of the three facies ( Rivera et al., 2018; Li et al., 2020; Zhang et al., 2020). Fig.
Shale oil exploration and development have made significant breakthroughs in Paleozoic marine shales and Mesozoic–Cenozoic lacustrine shales. However, the shale oil potential of older Precambrian sedi
