Palaeotemperatures, polar ice-volume, and isotope stratigraphy (Mg/Ca, delta 18O, delta 13C, 87Sr/86Sr) : the Early Cretaceous (Berriasian, Valanginian, Hauterivian)

, 2007
Temporal trends through Early Cretaceous time of δ13C, δ18O, Mg/Ca, and 87Sr/86Sr in calcite, and δ18O in seawater, are discussed using belemnites from SE France and SE Spain.

A High‐Resolution Belemnite Geochemical Analysis of Early Cretaceous (Valanginian‐Hauterivian) Environmental and Climatic Perturbations

Geochemistry, Geophysics, Geosystems, 2018
The Early Cretaceous Weissert event, characterized by a positive carbon isotope excursion and coincident with the Paraná‐Etendeka volcanism, saw a biogeochemical chain of events that ultimately led to an increase in carbon burial.
