Persistent Magma‐Rich Waves Beneath Mid‐Ocean Ridges Explain Long Periodicity on Ocean Floor Fabric

Geophysical Research Letters, 2022
The ocean floor makes up the majority of the Earth's surface and yet, its geomorphology is not fully understood. Recent debate has focused on whether sea level changes—driven by Milankovitch glacial cycles—generate the abyssal hill fabric of the ocean ...

Comparison of Recently Proposed Causes of Climate Change

Atmosphere, 2023
This paper compares the ideas contained in the main papers published on climate change since World War II to arrive at a suggested consensus of our present knowledge regarding climatic changes and their causes.

Genetic mechanism of multi-scale sedimentary cycles and their impacts on shale-oil distribution in Permian Lucaogou Formation, Jimusar Sag, Junggar Basin

Unconventional Resources, 2023
Complex lithofacies of Lucaogou Formation in Jimusar Sag promote strong heterogeneity of oil distribution in fine grained sedimentary rocks. It is of great significance to define the formation mechanism of fine-grained sedimentary rocks for favorable ...

Development and controlling factors of shale lithofacies cycles in a continental rift basin: A case study of Es4u in the Boxing Subsag of Dongying Sag, Bohai Bay Basin, China

Frontiers in Earth Science, 2023
The shale of the upper Es4 formation (Es4u), deposited during the Eocene in the Boxing Subsag of the Dongying Sag, is a typical set of lime-rich lacustrine shale in a continental rift basin.

GENERALIZED MILANKOVITCH CYCLES AND LONG-TERM CLIMATIC HABITABILITY [PDF]

The Astrophysical Journal, 2010
Although the Earth's orbit is never far from circular, terrestrial planets around other stars might experience substantial changes in eccentricity that could lead to climate changes, including possible "phase transitions" such as the snowball transition (or its opposite).

Milankovitch cycles and carboniferous climate

Geophysical Research Letters, 1993
Cyclical Permo‐Carboniferous sea level fluctuations have long been linked to glacial‐interglacial fluctuations on Gondwanaland. Similar to the Pleistocene, such fluctuations may in turn have been driven by variations in orbital insolation forcing. Herein we report results from climate model simulations that examine the effect of Milankovitch insolation

Exo-Milankovitch Cycles. I. Orbits and Rotation States [PDF]

The Astronomical Journal, 2018
Abstract The obliquity of the Earth, which controls our seasons, varies by only ∼2.°5 over ∼40,000 years, and its eccentricity varies by only ∼0.05 over 100,000 years. Nonetheless, these small variations influence Earth’s ice ages. For exoplanets, however, variations can be significantly larger.

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.
