Resumo:

Astronomical calculations reveal the Solar System’s dynamical evolution, including its chaoticity, and represent the backbone of cyclostratigraphy and astrochronology. An absolute, fully calibrated astronomical time scale has hitherto been hampered beyond ~50 million years before the present (Ma) because orbital calculations disagree before that age. Here, we present geologic data and a new astronomical solution (ZB18a) showing exceptional agreement from ~58 to 53 Ma. We provide a new absolute astrochronology up to 58 Ma and a new Paleocene–Eocene boundary age (56.01 ± 0.05 Ma). We show that the Paleocene–Eocene Thermal Maximum (PETM) onset occurred near a 405-thousand-year (kyr) eccentricity maximum, suggesting an orbital trigger. We also provide an independent PETM duration (170 ± 30 kyr) from onset to recovery inflection. Our astronomical solution requires a chaotic resonance transition at ~50 Ma in the Solar System’s fundamental frequencies.

Abstract. Ocean Drilling Program (ODP) Site 982 represents a key location for understanding the evolution of climate in the North Atlantic over the past 12 Ma. However, concerns exist about the validity and robustness of the underlying stratigraphy and astrochronology, which currently limits the adequacy of this site for high-resolution climate studies. To resolve this uncertainty, we verify and extend the early Pliocene to late Miocene shipboard composite splice at Site 982 using high-resolution XRF core scanning data and establish a robust high-resolution benthic foraminiferal stable isotope stratigraphy and astrochronology between 8.0 and 4.5 Ma. Splice revisions and verifications resulted in ∼ 11 m of gaps in the original Site 982 isotope stratigraphy, which were filled with 263 new isotope analyses. This new stratigraphy reveals previously unseen benthic δ18O excursions, particularly prior to 6.65 Ma. The benthic δ18O record displays distinct, asymmetric cycles between 7.7 and 6.65 Ma, confirming that high-latitude climate is a prevalent forcing during this interval. An intensification of the 41 kyr beat in both the benthic δ13C and δ18O is also observed ∼ 6.4 Ma, marking a strengthening in the cryosphere–carbon cycle coupling. A large ∼ 0.7 ‰ double excursion is revealed ∼ 6.4–6.3 Ma, which also marks the onset of an interval of average higher δ18O and large precession and obliquity-dominated δ18O excursions between 6.4 and 5.4 Ma, coincident with the culmination of the late Miocene cooling. The two largest benthic δ18O excursions ∼ 6.4–6.3 Ma and TG20/22 coincide with the coolest alkenone-derived sea surface temperature (SST) estimates from Site 982, suggesting a strong connection between the late Miocene global cooling, and deep-sea cooling and dynamic ice sheet expansion. The splice revisions and revised astrochronology resolve key stratigraphic issues that have hampered correlation between Site 982, the equatorial Atlantic and the Mediterranean. Comparisons of the revised Site 982 stratigraphy to high-resolution astronomically tuned benthic δ18O stratigraphies from ODP Site 926 (equatorial Atlantic) and Ain el Beida (north-western Morocco) show that prior inconsistencies in short-term excursions are now resolved. The identification of key new cycles at Site 982 further highlights the requirement for the current scheme for late Miocene marine isotope stages to be redefined. Our new integrated deep-sea benthic stable isotope stratigraphy and astrochronology from Site 982 will facilitate future high-resolution late Miocene to early Pliocene climate research.

This thesis investigates the early Miocene planktonic foraminifera from two sections Contessa section (Italy) and IODP Site U1406 (Newfoundland, Canada), to contribute to the open question of the Aquitanian/Burdigalian boundary. The Burdigalian stage lacks an official Global Stratotype Section and Point, and its base is provisionally set at 20.43 Ma and approximated by the calcareous nannofossil Helicosphaera ampliaperta FO. Following an integrated biostratigraphic approach, the results obtained from the two sections are reported and discussed in the manuscripts contained in this dissertation. For both sections, a new age model is proposed and their semiquantitative and quantitative analyses are presented for planktonic foraminifera, calcareous nannofossils and magnetostratigraphy. After the recognition of two hiatuses in the second section (Site U1406) other studies were performed, for a paleoecological characterisation of the planktonic foraminifera (with statistical analyses) and then a preliminary cyclostratigraphic study. This final and fourth study will eventually lead to the astronomical tuning of the Site and of the bioevents therein recognised. The successful correlation of the hiatuses to regional megahiatuses allowed us to investigate the early Neogene climate evolution from the perspective of the planktonic foraminifera assemblages. In conclusion, the Contessa section is correlated with other reference sections for the early Miocene. The first correlation was with the Santa Croce di Arcevia Section, which used to be the most complete lower Miocene section in the Mediterranean area (before its closure). The second correlation presented is with the IODP Site U1406 in order to compare the different results obtained from the Mediterranean and the North Atlantic integrated biostratigraphy. A third and final correlation is presented between the two sections here studied and the ODP Hole 926B (in the equatorial Atlantic at Ceara Rise), which is retained a reference section for biostratigraphic and chronostratigraphic schemes. These correlations also permit to enlighten the potentials of the Contessa section as a GSSP candidate for the Burdigalian stage. Concerning the Aquitanian/Burdigalian boundary as defined at the present day by the ICS, the Contessa Section contains such limit at 19.77 m where the calcareous nannofossil Helicosphaera ampliaperta first occurs. The integrated analysis allowed me to document such event in its standard stratigraphic position, within Chron C6Aar1n and occurring coherently with the other biomarkers of both foraminiferal and calcareous nannofossil biostratigraphy.
