Evaluation of the astronomical time scale for the Paleocene and earliest Eocene
Earth and Planetary Science Letters, 2010 The astronomical-tuned time scale is rapidly extended into the Paleogene but, due to the existence of an Eocene gap, different tuning options had to be presented for the Paleocene. These options differ both in number and tuning of ~405-kyr eccentricity related cycles and are only partially consistent with recalculated 40Ar/39Ar constraints for the ...

Present status of the astronomical (polarity) time-scale for the Mediterranean Late Neogene
Philosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 1999Sedimentary cycles may reflect orbitally induced climate oscillations and can then be used to construct astronomical time–scales. Following the initial tuning of the Late Pleistocene, the ‘anchored’ astronomical time–scale was extended to the base of the Pliocene, using palaeoclimatic records from Ocean Drilling Project (ODP) sites in the eastern ...

Astronomical time scale for the lower Doushantuo Formation of early Ediacaran, South China
Science Bulletin, 2018Nearly 90% of the Ediacaran Period (635-541 Ma) of the Neoproterozoic is represented by the Doushantuo Formation (DST Fm) in South China. Its lowest Member I is a 3.7 m-thick cap carbonate deposited at the termination of the Cryogenian Marinoan glaciation.

Time-scale and astronomical forcing of Serbian loess–paleosol sequences
Global and Planetary Change, 2014Abstract The loess in Vojvodina region in Northern Serbia is regarded as one of the thickest and most complete paleoclimate archives in Europe. Recent studies showed that loess in Vojvodina spans the last million years. Based on the interprofile correlation between two most important loess–paleosol sequences Stari Slankamen and Titel Loess Plateau a ...

Astronomic calibration of the late Oligocene through early Miocene geomagnetic polarity time scale
Earth and Planetary Science Letters, 2004 At Ocean Drilling Program (ODP) Site 1090 (subantarctic South Atlantic), benthic foraminiferal stable isotope data (from Cibicidoides and Oridorsalis) span the late Oligocene through early Miocene (f24-16 Ma) at a temporal resolution of f5 ky. Over the same interval, a magnetic polarity stratigraphy can be unequivocally correlated to the geomagnetic ...

An astronomical time scale of early Pliocene from the Mediterranean Sea, Egypt
Global and Planetary Change, 2022 Pliocene diachronism and mismatches between planktic foraminifera and nannofossil bioevents are clearly observed in the Mediterranean Sea. Hence, astronomical tuning combined with calcareous nannofossils and plankton foraminiferal biozones constitutes ...
