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).

Rock Magnetic Cyclostratigraphy of Permian Loess in Eastern Equatorial Pangea (Salagou Formation, South-Central France)

open access: yesFrontiers in Earth Science, 2020
We present the findings from analysis and modeling of a stratigraphic series of magnetic susceptibility (MS) data measured with a portable MS meter from the Permian Salagou Formation loessite (south-central France).

Cyclostratigraphy of Lower Permian alkaline lacustrine deposits in the Mahu Sag, Junggar basin and its stratigraphic implication

open access: yesFrontiers in Earth Science, 2023
The Lower Permian Fengcheng Formation of the Mahu Sag is one of the most potentially petroliferous sequences in China, and its unique alkaline lacustrine deposits provide important information on the paleoclimate and paleoenvironment of the early Permian.

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.

Comparison of variations in sediment accumulation rates of the upper part of Zakeen Formation through cyclostratigraphic study in 2SK-1 and 2SKD-1 wells in Salman gas field [PDF]

open access: yesJournal of Stratigraphy and Sedimentology Researches, 2020
The Zakeen Formation is one of the possible gas reservoirs in the Zagros sedimentary basin. In this paper, the cyclostratigraphic study of the upper part of the Zakeen Formation was performed by using evolutionary spectral analysis methods.

Cyclostratigraphy of the Miocene Nakayama Formation on Sado Island in central Japan and paleoceanographic implications

open access: yesProgress in Earth and Planetary Science
Although siliceous sediments have the potential to reveal an enigmatic Miocene climate evolution, problems with age model construction are tough to beat. Cyclostratigraphy is a useful tool for the construction of a high-resolution age model. In the Japan

Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement

open access: yesGeophysical Monograph Series, Page 27-82., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

A hundred years of Milutin Milankovic's climate change theory-geological implications [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva, 2020
Milanković’s cycles theory published hundred years ago is the most important theory in climate science and had great influence on Earth disciplines. Nevertheless, his work waited for more than fifty years for confirmation.

Effects of astronomical orbital cycle and volcanic activity on organic carbon accumulation during Late Ordovician–Early Silurian in the Upper Yangtze area, South China

open access: yesPetroleum Exploration and Development, 2021
Based on field outcrop data, the effects of cyclic change of astronomical orbit and volcanic activity on organic carbon accumulation during the Late Ordovician – Early Silurian in the Upper Yangtze area were studied using cyclostratigraphic and ...
