Oceanic Anoxic Event 2 (OAE2), spanning the Cenomanian-Turonian boundary (CTB), represents one of the largest perturbations in the global carbon cycle in the last 100 Myr. The d13Ccarb, d13Corg, and d18O chemostratigraphy of a black shale-bearing CTB succession in the Vocontian Basin of France is described and correlated at high resolution to the European CTB reference section at Eastbourne, England, and to successions in Germany, the equatorial and midlatitude proto-North Atlantic, and the U.S. Western Interior Seaway (WIS). Delta13C (offset between d13Ccarb and d13Corg) is shown to be a good pCO2 proxy that is consistent with pCO2 records obtained using biomarker d13C data from Atlantic black shales and leaf stomata data from WIS sections. Boreal chalk d18O records show sea surface temperature (SST) changes that closely follow the Delta13C pCO2 proxy and confirm TEX86 results from deep ocean sites. Rising pCO2 and SST during the Late Cenomanian is attributed to volcanic degassing; pCO2 and SST maxima ... : SECTION, heigh [m] gives the measured stratigraphic height above base of measured section. ...
