Deep-sea hiatus record reveals orbital pacing by 2.4 Myr eccentricity grand cycles [PDF]

open access: yesNature Communications
Astronomical forcing of Earth’s climate is embedded in the rhythms of stratigraphic records, most famously as short-period (104–105 year) Milankovitch cycles.

The Impact of Pleistocene Glacial Cycles on the Evolutionary Diversification of the Arctic-Alpine Silene acaulis Species Complex. [PDF]

open access: yesMol Ecol
ABSTRACT 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.

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.

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.

Low-latitude climate variability in the Heinrich frequency band of the Late Cretaceous greenhouse world [PDF]

open access: yesClimate 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 ...

Disentangling the Evidence of Milankovitch Forcing From Tree-Ring and Sedimentary Records

open access: yesFrontiers in Earth Science, 2022
Tree-ring records constitute excellent high-resolution data and provide valuable information for climate science and paleoclimatology. Tree-ring reconstructions of past temperature variations agree to show evidence for annual-to-centennial anomalies in ...

Earth Orbit v2.1: a 3-D visualization and analysis model of Earth's orbit, Milankovitch cycles and insolation [PDF]

open access: yesGeoscientific Model Development, 2014
Milankovitch theory postulates that periodic variability of Earth's orbital elements is a major climate forcing mechanism, causing, for example, the contemporary glacial–interglacial cycles.

Enhanced climate variability in the tropics: a 200 000 yr annual record of monsoon variability from Pangea's equator [PDF]

open access: yesClimate of the Past, 2011
A continuous series of 209 000 evaporite varves from the equator of arid western Pangea (age = −255 ma), as a proxy for surface temperature, has a complete suite of Milankovitch cycles and harmonics as expected for a rectified reaction to precession ...

Linking the Variation of Sediment Accumulation Rate to Short Term Sea-Level Change Using Cyclostratigraphy: Case Study of the Lower Berriasian Hemipelagic Sediments in Central Tunisia (Southern Tethys)

open access: yesFrontiers in Earth Science, 2021
High-resolution magnetic susceptibility and % CaCO3 records (5 to 10 cm sampling interval) are used to track astronomical cycles from a Lower Berriasian record from central Tunisia.
