Paleotemperature evolution and its driving mechanism during the formation of limestone-marl alternations in first member of Middle Permian Maokou Formation in Sichuan Basin

Shiyou shiyan dizhi, 2023
From the Late Carboniferous to the end of Middle Permian, the most intense glacial event in history of Phanerozoic occurred and it is also the last transition period from icehouse stage to greenhouse stage in geological history.

Milankovitch cycles and the astronomical time scale of the Zhujiang Formation in the Baiyun Sag, Pearl River Mouth Basin, China

Open Geosciences, 2022
The Zhujiang Formation in the Baiyun Sag, Pearl River Mouth Basin, China, is formed primarily in a deep-water continental slope environment. Its chronostratigraphic framework is based on biostratigraphy and sequence stratigraphy, and its geological ...

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 ...

Sedimentary facies and stacking patterns of fluvio‐deltaic and ‐estuarine deposits from the Palaeoarchean Moodies Group in the Stolzburg Syncline (Barberton Greenstone Belt, South Africa)

The Depositional Record, Volume 12, Issue 4, September 2026.
Drillcore BASE‐5B from the Stolzburg Syncline, Barberton Greenstone Belt, reveals a coarsening‐upward, river‐dominated fluvio‐deltaic succession transitioning upward to a fining‐upward, tide‐dominated‐estuarine succession. Abstract Investigating fluvio‐marine depositional environments from early geological times is of great importance, as they provide ...

Are Species Distribution Models That Use Climate Variables Suitable to Forecast the Changing Distribution of Freshwater Organisms?

Freshwater Biology, Volume 71, Issue 9, September 2026.
ABSTRACT Species distribution models can be used to identify locations with environmental conditions suitable for populations in the past, present and future. However, climate variables commonly applied in species distribution models may be unsuitable for freshwater species because their explanatory power is difficult to assess.

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

Geochemistry, 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.

Cycle [PDF]

, 2023
Cycle, 2023, consists of 28 midfire cups in a gradient of colour from white to pink. Cycle references the loss of a personal cycle (from the removal of a uterus) but a reconnection to a universal cycle—celebrating/mourning the felt changes in the artist’

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

Journal 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

Simulating sub-Milankovitch climate variations associated with vegetation dynamics [PDF]

, 2006
International audienceClimate variability at sub-Milankovitch periods (between 2 and 15 kyr) is studied in a set of transient simulations with a coupled atmosphere/ocean/vegetation model of intermediate complexity (Climber-2).

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

Journal 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).
