d(13)C chemostratigraphy in the Lower-Middle Ordovician succession of Oland (Sweden) and the global significance of the MDICE
Based on the Tingskullen drillcore, we present the first continuous carbon isotope stratigraphy from the Lower-Middle Ordovician orthoceratite limestone of oland, Sweden. The extremely condensed Tremadocian and Floian stages include large gaps as well as the Ceratopyge Regressive Event and the widespread Evae transgression accompanied by prominent shifts in the C-13 record. The Dapingian and Darri
