Time-calibrated Milankovitch cycles for the late Permian. [PDF]
Nat Commun, 2013 AbstractAn important innovation in the geosciences is the astronomical time scale. The astronomical time scale is based on the Milankovitch-forced stratigraphy that has been calibrated to astronomical models of paleoclimate forcing; it is defined for much of Cenozoic–Mesozoic.

Enhancing in search of Milankovitch cycles from stratigraphic record using convex optimization algorithm [PDF]
Scientific ReportsAccurately identifying Milankovitch cycles has been a significant challenge in cyclostratigraphic studies, as it is essential for improving geochronology.

Proterozoic Milankovitch cycles and the history of the solar system. [PDF]
Proc Natl Acad Sci U S A, 2018 SignificancePeriodic 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 history of our solar ...

When volcanoes record Milankovitch cycles
Frontiers in Earth ScienceCyclic fluctuations in the frequency and intensity of volcanic activity are recorded during periods of global climate change. Volcano-sedimentary successions (e.g., in near-coastal environments) may reveal the interplay of glacio-eustatic fluctuations ...

A dynamical systems perspective on the Mid-Pleistocene Transition. [PDF]
J R Soc N ZABSTRACT Long‐term cooling of Earth's climate led to repeated glaciations that from the Pliocene (5.3–2.6 Ma) into the Pleistocene (2.6 Ma–11.7 ka) became increasingly cold and asymmetric. Whether this progressive change in global climate was forced by external drivers, or arose entirely from internal feedbacks, is debated.

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

The Impact of Pleistocene Glacial Cycles on the Evolutionary Diversification of the Arctic-Alpine Silene acaulis Species Complex. [PDF]
Mol EcolABSTRACT Arctic‐alpine species are highly sensitive to long‐term temperature changes and associated glacial cycles due to their occurrence in cold environments to which they are adapted and spatially restricted. Unravelling their evolutionary responses to past climatic fluctuations can provide new insights into their diversification.

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.

Geophysical Monograph Series, Page 263-304., 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.
