New geochemical identification fingerprints of volcanism during the Ordovician-Silurian transition and its implications for biological and environmental evolution
S Yang, W Hu, J Fan, Y Deng - Earth-Science Reviews, 2022 - Elsevier
Volcanism had been an important factor in several geological events, usually recorded by
volcanic ash layers (bentonites). However, most volcanic eruption materials were dispersed …
