Volcanism, CO2 and Palaeoclimate: A Late Jurassic-Early Cretaceous Carbon and Oxygen Isotope Record
Weissert, Helmut, Erba, Elisabetta, Journal of the Geological Society
Abstract:
A composite Tethyan Late Jurassic-Harly Cretaceous carbon and oxygen isotope curve is presented. C-isotope data provide information on the evolution and perturbation of the global carbon cycle. O-isotope data are used as a palaeotemperature proxy in combination with palaeontological information. The resulting trends in climate and in palaeoecanography are compared with biocalcification trends and oceanographic conditions favouring or inhibiting biocalcification. Positive C-isotope anomalies in the Valanginian and Aptian correlate with episodes of increased volcanic activity regarded as a source of excess atmospheric carbon dioxide. A major warming pulse accompanies the …
