Abstract:
This dataset includes geochemical and geophysical data obtained from four boreholes in the western part of the Bohemian Cretaceous Basin (central Europe). The study interval covers the latest Cenomanian through lower Middle Turonian (c. 94.5 – 92.5 Myr ago). New data on the carbon-isotope ratios in bulk organic matter (d13Corg) from the cores 4523-A (Sedlec) and 4530-A (Horní Beřkovice) document the major carbon-isotope anomaly of the Oceanic Anoxic Event II and small-scale isotope excursions of the Lower Turonian interval. A greyscale-density profile of the core 4523-A and archive downhole resisitivity logs from two boreholes J-719670 and J-650704 provide high-resolution records of lithological variations of Milankovitch origin; these data were used to develop an astronomical time scale and interpret the phasing of orbital eccentricity in the study interval. A transient record of astronomical cyclicity was identified in major-element ratios (Si/Al) from the core Bch-1.
