Mechanisms of near‐normal sea water dolomitisation: Mesohaline‐reflux or syn‐depositional?
The Depositional Record, Volume 12, Issue 1, February 2026.This study investigates the dolomitisation of the Eocene Dammam Formation on the Arabian Plate using petrographic, mineralogical, geochemical and isotopic analyses. The findings reveal two distinct dolomite types, formed primarily through normal‐to‐mesohaline sea water dolomitisation, challenging previous models such as sabkha‐meteoric mixing.

The Depositional Record, Volume 12, Issue 1, February 2026.The deep paleo‐lake, characterised by low energy and moderate salinity, facilitated the input of fine‐grained minerals and the development of aquatic organic matter. Under the combined influence of the sedimentary environment and material source, mineral‐bound organic matter was formed, which played a crucial role in the enrichment of organic matter ...

State‐Dependence of Polar Amplification in an Idealized GCM
Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.Abstract Polar amplification (PA) is a robust feature of contemporary climate change, but its state‐dependence across different climate conditions is poorly understood despite potential relevance to paleoclimate records and future projections. Here we examine the state‐dependence of PA across a wide range of climate states in an idealized moist general

Quantitative foraminiferal and palynomorph biostratigraphy of the Paleogene in the southwestern Barents Sea [PDF]
, 2004 The stratigraphic distribution of both foraminifera and dinoflagellate cysts is recorded from the Paleocene to Eocene Torsk Formation in 12 petroleum exploration wells drilled in the southwestern Barents Sea.

Altered Ocean Temperature Gradients Are Key to Miocene South Asian Monsoon Evolution
Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.Abstract Indian Ocean sea surface temperature (SST) gradients influence South Asian summer monsoon (SASM) strength. Middle Miocene proxy records show reversed Arabian Sea zonal gradients (warmer west than east) and reduced Indian Ocean meridional gradients compared to today—patterns coupled models cannot reproduce, hindering accurate SASM simulation ...

Uppermost Jurassic to Lower Cretaceous benthic foraminiferal biostratigraphy at ODP Site 765 on the Argo Abyssal Plain. [PDF]
, 1992 Benthic foraminifers were studied in 99 samples collected from the lower 200 m of Hole 765C. The studied section ranges from the Tithonian to Aptian, and benthic foraminifers can be subdivided into five assemblages on the basis of faunal diversity and ...

Geoscience Data Journal, Volume 13, Issue 1, January 2026.Comparison between observed and predicted landslide areas in log scale. ABSTRACT This study aims to establish a regional model for predicting seismic landslide areas. Using the 2013 Minxian earthquake‐induced landslide database as the research foundation, mathematical statistics and GIS techniques were applied to predict landslide areas through the ...

Geoarchaeology, Volume 41, Issue 1, January/February 2026.ABSTRACT The Pyrenees have been considered a natural barrier for prehistoric populations. However, in recent years, Palaeolithic research has established connections between the two sides through the analysis of cherts. Among others, the presence of Chalosse cherts in sites on the southern slopes of the Pyrenees has proven the mobility of objects and ...
