Cyclostratigraphy concepts, definitions, and applications [PDF]

open access: yesNewsletters on Stratigraphy, 2007
Cyclostratigraphy is the subdiscipline of stratigraphy that deals with the identification, characterization, correlation, and interpretation of cyclic variations in the stratigraphic record and, in particular, with their application in geochronology by improving the accuracy and resolution of time-stratigraphic frameworks.

Rock Magnetic Cyclostratigraphy of the Carboniferous Mauch Chunk Formation, Pottsville, PA, United States

open access: yesFrontiers in Earth Science, 2019
A rock magnetic cyclostratigraphy study was conducted on the Carboniferous Mauch Chunk Formation red beds at Pottsville, Pennsylvania to determine if Milankovitch climate forcing could be detected in these terrestrial, fluvial deposits with hematite as ...

Astronomical forcing in Lopingian coal-bearing cycles: a case study of Bijie area in northwestern Guizhou

open access: yes矿业科学学报, 2022
To systematically study the sedimentary cycles and their astronomical forcing in the Lopingian coal-bearing series in Bijie area, northwestern Guizhou, the GR logging data from four boreholes in this area were analyzed and tested by using time series ...

Ordovician cyclostratigraphy and astrochronology

open access: yesGeological 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).

Orbital and Millennial‐Scale Cycles Paced Climate Variability During the Late Paleozoic Ice Age in the Southwestern Gondwana

open access: yesGeochemistry, Geophysics, Geosystems, 2020
Orbital cycles are related to variations of Earth's orbit through time and exert profound control on glacial and interglacial climates due to changes in insolation.

The Cyclostratigraphy Intercomparison Project (CIP) [PDF]

open access: yesEarth-Science Reviews, 2019
Cyclostratigraphy is an important tool for understanding astronomical climate forcing and reading geological time in sedimentary sequences, provided that an imprint of insolation variations caused by Earth's orbital eccentricity, obliquity and/or precession is preserved (Milankovitch forcing).
