Proterozoic Milankovitch Cycles and the History of the Solar System [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2018 Significance Periodic variations in Earth’s orbit and rotation axis occur over tens of thousands of years, producing rhythmic climate changes known as Milankovitch cycles. The geologic record of these climate cycles is a powerful tool for reconstructing geologic time, for understanding ancient climate change, and for evaluating the ...

Orbital eccentricity and internal feedbacks drove the Triassic megamonsoon variability [PDF]
Scientific ReportsThe evolution of the Triassic megamonsoon was closely linked to Earth’s orbital variations. Despite recognizing secular orbital cycles as a fundamental pacemaker of the megamonsoon, the driving mechanisms remain unclear. Here, we use data-model synthesis

Application of porosity logs for cyclostratigraphic analysis in the absence of gamma ray logs [PDF]
Scientific ReportsHigh-resolution cyclostratigraphic and sequence stratigraphic analyses are often compromised and lead to incorrect interpretations due to the unavailability or critical, proven errors in the reference Gamma-Ray (GR) and Density (RHOB) logs in hydrocarbon

Deep-sea hiatus record reveals orbital pacing by 2.4 Myr eccentricity grand cycles [PDF]
Nature CommunicationsAstronomical forcing of Earth’s climate is embedded in the rhythms of stratigraphic records, most famously as short-period (104–105 year) Milankovitch cycles.

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]
Journal 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.

Low-latitude climate variability in the Heinrich frequency band of the Late Cretaceous greenhouse world [PDF]
Climate of the Past, 2014 Deep marine successions of early Campanian age from DSDP (Deep Sea Drilling Project) site 516F drilled at low paleolatitudes in the South Atlantic reveal distinct sub-Milankovitch variability in addition to precession, obliquity and eccentricity-related ...
