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

open access: yesUnconventional 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 ...

Regional Variations in Sea Ice and Primary Productivity in the Bering Sea During Marine Isotope Stage 11

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Marine Isotope Stage (MIS) 11 (424–374 ka) has long been an analog for Holocene climate because it is the most recent interglacial period with similar orbital conditions. However, there is global and regional variability in the climate response to MIS 11 warmth.

Temperature response of Mars to Milankovitch cycles [PDF]

open access: yesGeophysical 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 ...

Seeing Through the Noise: Implications for Signal Preservation in Sediment Flux Time Series From Erosional Systems

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 7, July 2026.
Abstract Allogenic forcing of sediment production generates sedimentary signals that we use to understand the past. These signals may be buffered or shredded by autogenic processes as they travel through sediment routing systems from source to sink. Studies on signal propagation tend to focus on either signal buffering by deterministic fluvial networks

Milankovitch cycles of terrestrial planets in binary star systems [PDF]

open access: yesMonthly 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.

Probabilistic Assessment of Variable Slip Rates of Offshore Buried Thrusts in the Central Adriatic Sea (Italy) Since the Pliocene Time

open access: yesTectonics, Volume 45, Issue 7, July 2026.
Abstract Understanding the recent tectonic activity of buried faults represents a challenge for scientists. In the offshore portion of the Northern and Central Apennines foredeep basin in the Central Adriatic Sea, Italy, high sedimentation rates, exceeding tectonic uplift since the Pliocene, and the offshore location are hampering the detection of ...

A Spreading‐Rate Dependence for Periodic Signals Embedded in Otherwise Aperiodic Abyssal Hills

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract I present evidence, through an empirical pre‐whitening analysis, that periodic signals are embedded in otherwise aperiodic abyssal hills across paleo‐spreading rates ranging from 1 to 9 cm/yr (half rate). Data are comprised of archival trackline and multibeam bathymetry profiles in north and south Atlantic Oceans, Pacific‐Antarctic Ridge ...

Milankovitch-driven cycles in the Precambrian of China: The Wumishan Formation

open access: yesJournal of Palaeogeography, 2013
Carbonate strata of the Mesoproterozoic Wumishan Formation in the Jixian area near Tianjin are ~3300 m thick and were deposited over some 100 million years (from ~1310±20 Ma to ~1207±10 Ma).

Loess Studies in Aotearoa New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Loess in Aotearoa New Zealand (ANZ) has been studied since its first documented recognition (on Banks Peninsula) in 1878 by Julius von Haast. A decade later, John Hardcastle revealed that southern ANZ loess was both glacial in origin and contained signals of past climates.

Terrestrial Analogs to Titan for Geophysical Research

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...
