Astronomical cycle driving of coal-bearing rock system rotations in the Permian Shihezi Formation at Renlou Coal Mine

Solid Earth Sciences
Marine terrestrial transitional sedimentary rocks of Renlou Coal Mine are developed in coal bearing rock formations, which exhibits obvious cyclicity. These sedimentary cycles have a good correspondence with astronomical cycle signals.

Identification of Milankovitch Cycles and Their Sedimentary Responses in Fine-Grained Depositional Strata on the Southwestern Margin of the Songliao Basin

Applied Sciences
A series of fault depressions developed in the Kailu area on the southwestern margin of the Songliao Basin, where thick lacustrine fine-grained sedimentary rocks were widely deposited during the initial faulting stage in the Early Cretaceous.

Interglacials, Milankovitch Cycles, Solar Activity, and Carbon Dioxide [PDF]

Journal of Climatology, 2014
The existing understanding of interglacial periods is that they are initiated by Milankovitch cycles enhanced by rising atmospheric carbon dioxide concentrations. During interglacials, global temperature is also believed to be primarily controlled by carbon dioxide concentrations, modulated by internal processes such as the Pacific Decadal Oscillation

Astronomical cycle identification and high-frequency sequence stratigraphy of the Middle Permian Lower Wuerhe Formation in the Mahu Sag, Junggar Basin

Frontiers in Earth Science
High-resolution stratigraphic analysis is essential for reconstructing sedimentary processes and constraining reservoir architecture, yet conventional methods commonly lack quantitative time control at fourth- and fifth-order (104–105 yr) scales ...

Milankovitch Cycles in Chalks, Danish North Sea, Detected by Use of Magnetic Susceptibility

, 2001
Subdivision of the Maastrichtian chalk from the Danish North Sea has proven to be difficult because of the homogenous composition and appearance.

Mending Milankovitch's theory: obliquity amplification by surface feedbacks

, 2013
. Milankovitch's theory states that orbitally induced changes in high-latitude summer insolation dictate the waxing and waning of ice sheets. Accordingly, precession should dominate the ice-volume response because it most strongly modulates summer ...

Milankovitch cycles in an equatorial delta from the Miocene of Borneo

Earth and Planetary Science Letters, 2017
The factors controlling sedimentary cyclicity in deltaic systems are a subject of intense debate, and more research, in different deltaic environments and time periods, is needed to better understand the possible mechanisms. Offshore and Pleistocene case studies are more common than proximal and more ancient, greenhouse-climate examples.

The ∼170 kyr astronomical cycle in the Early Permian Lucaogou Formation of the Junggar Basin

Frontiers in Earth Science
According to Milankovitch’s theory, periodic climate change in Earth’s history is controlled by the periodic changes in the Earth’s orbit and axis of rotation. Milankovitch cycle include eccentricity, obliquity, and precession cycles. In addition to them,
