Rivista Italiana di Paleontologia e Stratigrafia, 2016 Toarcian sections studied mainly in Europe have revealed the incidence of Milankovitch forcing with a well-developed, highly stable, 405 ky component of eccentricity, a short-term eccentricity of ~100 kyr, the cycle of obliquity ~36 kyr, and the ...

The Astronomical Pulse of Global Extinction Events
The Scientific World Journal, 2006 The linkage between astronomical cycles and the periodicity of mass extinctions is reviewed and discussed. In particular, the apparent 26 million year cycle of global extinctions may be related to the motion of the solar system around the galaxy ...

Downcurrent variation in submarine channel‐fill architecture from the shelf to upper slope
Sedimentology, EarlyView.ABSTRACT The transition between the shelf and the upper slope is often considered an area of sediment bypass, where steeper gradients increase flow velocities and maintain particles in suspension. In addition to transferring sediments into deeper basins, upper‐slope areas can also host channelised submarine deposits.

Temperature response of Mars to Milankovitch cycles [PDF]
Geophysical Research Letters, 2008 On Mars annual mean surface temperature near ±60° latitude varies predominately with precession and is not closely related to annual mean insolation. Based on the last few million years of orbital history, the precession cycle dominates in a narrow latitude range 54°–65°, in which the margins of the two ice‐rich permafrost layers in each hemisphere ...

Frontiers in Earth Science, 2019 A rock magnetic cyclostratigraphy study was conducted on the Carboniferous Mauch Chunk Formation red beds at Pottsville, Pennsylvania to determine if Milankovitch climate forcing could be detected in these terrestrial, fluvial deposits with hematite as ...

Tectonic Re‐Organization and Onset of South Caspian Escape Tectonics at 1.8–2.4 Ma
Basin Research, Volume 38, Issue 6, November‐December 2026.We show that the presently active tectonics of the South Caspian began relatively recently, likely in the range 1.8–2.4 Myr and replacing an older tectonic configuration ending in the Miocene at ~6 Ma. The various short‐lived stages in the destruction of the South Caspian have potential for insight into the late stages of basin closure and the ...

Milankovitch cycles of terrestrial planets in binary star systems [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 The habitability of planets in binary star systems depends not only on the radiation environment created by the two stars, but also on the perturbations to planetary orbits and rotation produced by the gravitational field of the binary and neighbouring planets.

Soil modulation of Quaternary glacial-interglacial cycles
GeodermaSinusoidal Milankovitch orbital variations do not match the sawtooth pattern of descent into glaciation followed by abrupt termination to greenhouse interglacials seen in records of marine shale, speleothems, and ice cores.

High‐ and Low‐Latitude Insolation Forcing Drives the Half‐Precession Cycle in Winter Arctic Sea Ice
Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract The half‐precession cycle is a key climatic signal in global climate system, linking high‐ and low‐latitude climate variability and bridging orbital‐ and millennial‐scale climate changes. While it characterizes tropical insolation, its origin in high‐latitude climate records remains unclear. Based on a transient climate simulation spanning the
