AbstractThe Neoproterozoic oxygenation event (NOE) likely began earlier than 800 Ma, raising oxygen levels in the Earth's atmosphere-ocean system and, thus, setting the stage for the emergence and diversification of animals. However, the redox history of the oceans during the following Cryogenian Period (similar to 720-635 Ma) remains poorly constrained. Here, we present a biogeochemical study based on Mo-isotope (this study) and Fe, C, Mo abundance data (previously reported data) for black shales of the similar to 660-Ma Datangpo Formation in the Minle section of the Nanhua Basin, South China. Iron speciation data indicate that the study samples were most likely deposited under euxinic conditions. The studied samples yield two clusters of delta Mo-98 data: +0.98 parts per thousand to +1.14 parts per thousand [+1.06 +/- 0.06 (SD) parts per thousand] and -0.13 parts per thousand to +0.68 parts per thousand ( + 0.65 +/- 0.31 parts per thousand), respectively, with the higher values found mostly in the lowermost black shales. The variably lower delta Mo-98 values probably do not reflect contemporaneous open-ocean seawater composition owing to lower aqueous H2S concentrations caused by substantial watermass restriction (as evidenced by Mo-TOC covariation patterns), whereas the high delta Mo-98 values may record contemporaneous Cryogenian seawater values. The seawater 898Mo values from our study at similar to 660 Ma are similar to previously reported seawater delta Mo-98 values at similar to 750 Ma (+1.11 parts per thousand) and similar to 640Ma (+1.15 parts per thousand), implying the existence of widespread oceanic anoxia throughout the Cryogenian. Because the subsequent Ediacaran Period shows evidence of greater oceanic oxygenation based on multiple geochemical proxies, our findings suggest that the process of oceanic oxygenation proceeded slowly during the Cryogenian Period. This may have been an important factor in delaying the first appearance of metazoans until the late Cryogenian and their diversification until the Ediacaran.\
