The three Cretaceous oceanic large igneous provinces of Kerguelen, Ontong Java, and Caribbean have been widely regarded as the triggers of the two Cretaceous global oceanic anoxic events. Synchronicity is the premise for ascribing a causal relationship between an oceanic large igneous province and an oceanic anoxic event. However, owing to the detrimental effect of seawater alteration on commonly used dating materials in oceanic basalts, the ages that have been published for oceanic large igneous provinces are not all robust. In this study, we compiled all published dating results for oceanic large igneous provinces and assessed the robustness of each age data. Results show that although the quality-filtered robust ages of the oceanic large igneous provinces can provide evidence of the existence of contemporaneous eruptions with the oceanic anoxic events, the eruptive duration and tempo of the oceanic large igneous provinces remain unclear. More age data are required to constrain the possible causal relationship between the three oceanic large igneous provinces and the two Cretaceous global oceanic anoxic events.
