Abstract

The long (700 m) Hauterivian to Albian Adriatic Platform section mainly from Mljet Island, Croatia underwent little post-Mesozoic burial or little later diagenesis. Consequently its smoothed δ13C and δ18O record from calcite lime mudstone matrix provides one of the most continuous stable-isotope curves from an Early Cretaceous platform. This record captures the carbon isotope excursions (CIEs) and oceanic anoxic events (OAE1a, b, c) evident in published hemipelagic sections, with the added advantage of providing information on the shallow platform response to the OAEs. The platform facies appear to have been little affected by the OAEs, except for OAE1a when deposition of organic-rich laminated limestones occurred in local downwarps.
