Ordovician cyclostratigraphy and astrochronology
Geological Society, London, Special Publications, 2023 Abstract Cyclostratigraphy is an important tool for understanding astronomical climate forcing and for reconstructing geological time in sedimentary sequences, provided that an imprint of insolation variations caused by Earth's orbital eccentricity, obliquity and precession is preserved (Milankovitch forcing).

Climatic changes and astrochronology: an Ordovician perspective [PDF]
, 2020 Review of current progress in Mid to Late Ordovician astrochronological studies exposes some important issues related to cyclostratigraphical studies, including the completeness and correlation of successions, and the connection between inferred astronomical cycles and geological events recorded in the sedimentary record.

The Astronomical JournalThe planets’ gravitational interaction causes rhythmic changes in Earth’s orbital parameters (also called Milanković cycles), which have powerful applications in geology and astrochronology.

Geochemistry, Geophysics, GeosystemsThe pattern of geomagnetic polarity changes during the Early Carboniferous (Mississippian) is not known in detail. This information sparsity is addressed by determining a magnetostratigraphy from the late Asbian (late Visean at ∼333 Ma) in Trowbarrow ...

Mediterranean contributions to cyclostratigraphy and astrochronology
Sedimentology, 2008 AbstractIn 1895, G.K. Gilbert suggested that rhythmical repetition of patterns in the sequences of strata correspond to orbital variations and could provide a chronology for Earth history. This suggestion remained a heuristic hypothesis in need of testing; in this, the Mediterranean region latterly played a crucial role.

Astrochronology of the Mediterranean Langhian between 15.29 and 14.17Ma
Earth and Planetary Science Letters, 2010 An integrated high-resolution magnetobiocyclostratigraphy including radioisotopic dating and astronomical tuning is presented for the interval between 15.29 and 14.17 Ma in the marine La Vedova section in northern Italy. The natural remanent magnetization is carried by the iron sulphide greigite and the resultant magnetostratigraphy can be correlated ...

, 2020 <p>Large uncertainties exist on the numerical ages of the stages in the Early Cretaceous which hamper from an accurate reconstruction of the past climate. Recent radio-astrochronologic data suggest to move the ages of the Tithonian to the Hauterivian stages by 3 to 5 Myr toward younger ages (Lena et al., 2019; Aguirre-Urreta et ...
