- This influential paper tests the utility of osmium isotopes for palaeoenvironmental studies and demonstrates that volcanism likely triggered oceanic anoxic events. The work confirms the global distribution of an Os-isotope event recorded in marine sediments 94 million years ago, relates this to large igneous province volcanism, and defines its timing and duration. Interactions between volcanism, weathering, and oceanic anoxia led to black shales deposition in basins world-wide (OAE2). These beds represent 60% of the World's petroleum source rocks. The work forms a basis for subsequent projects studying OAE2 (e.g. Sullivan et al., 2020. Geochim. Cosmochim. Acta).
