Construction of a precise early Eocene orbital cyclostratigraphy for DSDP Site 80-550 from the Goban Spur, North Atlantic
We constructed a precise early Eocene orbital cyclostratigraphy for DSDP Site 550 (Leg 80, Goban Spur, North Atlantic) utilizing precession related cycles as represented in a high resolution X-Ray Fluorescence based Barium core log. Based on counting of those cycles, we constrain the exact timing of...

We constructed a precise early Eocene orbital cyclostratigraphy for DSDP Site 550 (Leg 80, Goban Spur, North Atlantic) utilizing precession related cycles as represented in a high resolution X-Ray Fluorescence based Barium core log. Based on counting of those cycles, we constrain the exact timing of two volcanic ash layers in Site 550 which correlate to ashes +19 and -17 of the Fur Formation in Denmark. The ashes, relative to the onset of the Paleocene/Eocene Thermal Maximum (PETM), are offset by 862 kyr and 672 kyr, respectively.
