Abstract:

This file includes new data on the carbon-isotope composition of bulk organic matter (δ¹³Corg) and organic carbon contents (TOC, wt%) from the core 4523-A (Sedlec), western part of the Bohemian Cretaceous Basin. The interval covers the uppermost Cenomanian through Middle Turonian. Samples were analyzed in the Stable Isotope Laboratory of the Geological Survey, Prague. Inorganic carbon was removed before analysis by acid washing with HCl followed by rinsing with water, drying at 60 °C and homogenisation. Carbon-isotope measurements were performed by flash combustion in Fisons 1108 elemental analyzer coupled with isotope ratio mass spectrometer Delta V Advantage (ThermoFisher, Bremen, Germany) in continuous flow regime. Sample size was adjusted to contain a sufficient amount of carbon. Isotope ratios are reported as delta (δ) values and expressed relative to VPDB. International standards NBS 22 (-30,031‰), IAEA-CH-7 (-32,151‰) and in-house standard Soil (-27,82 ‰) were used to verify proper instrument function, and to conduct a normalization procedure. The long-term reproducibility is better than ±0.15‰.
