The knowledge of regional chronostratigraphy and paleoenvironment enables the prediction of the stratigraphic and geographic distribution of black shales with precision, as well as the understanding of local heterogeneity in regional- or global-scale oceanographic changes, such as oceanic anoxic events. Through sample re-analyses, this study provides a high-resolution Mesozoic chronostratigraphic and paleoenvironmental…
