Effect of end Triassic CO2 maximum on carbonate sedimentation and

Correlation of stratigraphic sections from different continents suggests a worldwide interruption of carbonate sedimentation at the Triassic Jurassic boundary which coincided with one of the most catastrophic mass extinctions in the Phanerozoic Both events are linked by a vulcanogenic maximum of carbon dioxide which led to a temporary undersaturation of sea water with respect to aragonite
