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.

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 ...

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.

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