contents Well-log data was acquired in a Late Cretaceous section of the Espírito Santo basin (western South Atlantic). Cyclostratigraphic techniques were used to explore the eventual pacing of orbital cycles in the deposition of sequences. The frequency ratio method was used to interpret the orbital cycles and based on this a long-eccentricity signal was interpreted and extracted to create a floating time-scale. Using a seismic horizon associated Cretaceous-Paleogene transition, a strong shift in the natural gamma-ray data was anchored to an age of 66.0 Ma producing an anchored astronomical time-scale placed between late Albian and early Ypresian.
