The Cyclostratigraphy Intercomparison Project (CIP) [PDF]

Earth-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).

Temperature‐Driven Silicate Weathering Feedbacks Terminated the Middle Eocene Climatic Optimum

Geophysical Research Letters
Continental hydroclimate dynamics and its responses during the Middle Eocene Climatic Optimum (MECO, ∼40 Ma) remain largely unexplored. Here, we present high‐resolution multi‐proxy records from four East Asian lake basins that demonstrate precipitation ...

Cyclostratigraphy and astrochronology: Case studies from China [PDF]

Palaeogeography, Palaeoclimatology, Palaeoecology, 2020
A high-precision geologic time scale is the essential key for understanding the Earth's evolutionary history and geologic processes. Astronomical tuning of orbitally forced stratigraphic records to construct high-resolution Astronomical Time Scales (ATS) has led to a progressive refinement of the geologic time scale over the past two decades.

Aligning and synchronization of MIS5 proxy records from Lake Ohrid (FYROM) with independently dated Mediterranean archives: implications for DEEP core chronology [PDF]

Biogeosciences, 2016
The DEEP site sediment sequence obtained during the ICDP SCOPSCO project at Lake Ohrid was dated using tephrostratigraphic information, cyclostratigraphy, and orbital tuning through the marine isotope stages (MIS) 15-1. Although this approach is suitable

On the peritidal cycles and their diagenetic evolution in the Lower Jurassic carbonates of the Calcare Massiccio Formation (Central Apennines)

Geologica Carpathica, 2015
This paper shows the environmental changes and high-frequency cyclicity recorded by Lower Jurassic shallow-water carbonates known as the Calcare Massiccio Formation which crop out in the central Apennines of Italy.

Nonmarine time-stratigraphy in a rift setting: An example from the Mid-Permian lower Quanzijie low-order cycle Bogda Mountains, NW China

Journal of Palaeogeography, 2015
Sedimentological and stratigraphic studies of seven stratigraphic sections of Permian Hongyanchi (HYC) and Quanzijie (QZJ) low-order cycles (LCs) in the Tarlong-Taodonggou half graben and Dalongkou area in Bogda Mountains, NW China, demonstrate effective

Toward a Robust Plio‐Pleistocene Chronostratigraphy for ODP Site 762

Geophysical Research Letters, 2020
The advent of rapidly acquired proxy records provides paleoceanographers and paleoclimatologists with a wealth of high‐resolution data. These data are a boon for the community, as they enable millennial or even submillennial scale interpretation of past ...

Astronomically forced lake-level fluctuations with impact on sand-body distribution of the oligocene Huagang Formation in the Xihu Depression, east China sea shelf basin

Frontiers in Earth Science
The Late Oligocene Huagang Formation in the Xihu Depression, East China Sea Shelf Basin, records typical braided river delta deposits. However, the influence of astronomical forcing on sand-body distribution remains unclear.
