Effect of end-Triassic CO2 maximum on carbonate sedimentation and marine mass extinction
@article{Hautmann2004EffectOE, title={Effect of end-Triassic CO2 maximum on carbonate sedimentation and marine mass extinction}, author={Michael Hautmann}, journal={Facies}, year={2004}, volume={50}, pages={257-261} }
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 and calcite and a corresponding suppression of carbonate sedimentation including non-preservation of…
