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 ...

Enhancing in search of Milankovitch cycles from stratigraphic record using convex optimization algorithm [PDF]

Scientific Reports
Accurately identifying Milankovitch cycles has been a significant challenge in cyclostratigraphic studies, as it is essential for improving geochronology.

When volcanoes record Milankovitch cycles [PDF]

Frontiers in Earth Science
Cyclic 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, controlling erosional vs. aggradational processes, and the pattern of volcanic activity. However, the

Pacing of Paleozoic macroevolutionary rates by Milankovitch grand cycles [PDF]

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance There has been long-standing debate about the relative roles of intrinsic biotic interactions vs. extrinsic environmental factors as drivers of biodiversity change. Here, we show that, relatively early in the history of complex life, Milankovitch “grand cycles” associated with astronomical rhythms explain between 9 and 16%

Utilizing Maximum Entropy Spectral Analysis (MESA) to identify Milankovitch cycles in Lower Member of Miocene Zhujiang Formation in north slope of Baiyun Sag, Pearl River Mouth Basin, South China Sea

Open Geosciences, 2019
Logs in the petroleum boreholes indirectly records the sedimentary cycles in the deep burial formation. In order to extract and understand the periodicity and cyclicity, it is necessary to process the data by digital signal analysis method.

Milankovitch cycles in banded iron formations constrain the Earth–Moon system 2.46 billion years ago [PDF]

Proceedings of the National Academy of Sciences of the United States of America, 2022
The long-term history of the Earth-Moon system as reconstructed from the geological record remains unclear when based on fossil growth bands and tidal laminations. A possibly more robust method is provided by the sedimentary record of Milankovitch cycles

Time-calibrated Milankovitch cycles for the late Permian [PDF]

Nature Communications, 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.

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

Geoscientific 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.

Toward generalized Milankovitch theory (GMT) [PDF]

Climate of the Past
In recent decades, numerous paleoclimate records and results of model simulations have provided strong support for the astronomical theory of Quaternary glacial cycles formulated in its modern form by Milutin Milankovitch.

The Dependence of Earth Milankovitch Cycles on Martian Mass [PDF]

Publications of the Astronomical Society of the Pacific
Abstract The Milankovitch cycles of Earth result from gravitational interactions with other bodies in the solar system. These interactions lead to slow changes in the orbit and angular momentum vector of Earth, and correspondingly influence Earth’s climate evolution. Several studies have shown that Mars may play a
