Kinematics of Burial Remagnetizations in Fold‐and‐Thrust Belts: A Case Study From the South Pyrenean Foreland Basin (NE Spain)

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract This study investigates two burial‐related remagnetizations in the Jaca–Pamplona foreland basin (Southern Pyrenees): one with dual polarity and a positive reversals test, and another with only reverse polarity. These components, labeled C3 and C4 based on their mean unblocking temperatures, were identified from a paleomagnetic analysis of 142 ...

Site 1217

, 2002
Site 1217 (16°52.02´N, 138°06.00´W; 5342 meters below sea level [mbsl]; Fig. F1) is one of seven sites drilled to target upper Paleocene crust along a latitudinal transect during Leg 199 and will be used to investigate paleoceanographic processes in the ...

Channel Evolution During Drawdown of Iron Gate and Copco I Reservoirs, Klamath River, CA

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract This study used the world's largest dam removal on the Klamath River to investigate channel evolution in unconsolidated silt and clay sediment during reservoir drawdown. Timelapse imagery revealed retrogressing rotational slides and flowslides as key sources of sediment to the re‐emerging channels.

Modeling Large Dust Aerosols in the Community Earth System Model Version 2 (CESM2)

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 4, April 2026.
Abstract Dust aerosols have a wide size distribution from less than 0.1 to over 100 μm and dominate Earth's atmospheric aerosol mass. However, most Earth system models (ESMs) inadequately represent dust aerosols larger than 10 μm in diameter, limiting the accuracy of the simulated dust cycle and climate impacts.

Geochemistry of Ni in the Cretaceous-Tertiary succession Fiskeler (Fish Clay) at Stevns Klint (Denmark): cheto-smectite of the black marl [PDF]

Journal of the Serbian Chemical Society, 2006
The Cretaceus-Tertiary (KT) boundary at Stevns Klint (the Højerup succession), Fiskeler, consists of a thin red clay layer overlain by a thick one of black marl. These two layers are made up mainly from cheto-smectite and biogenic calcite. The black marl

Soil texture prevails over vegetation change in determining soil organic carbon storage in an African savanna

Journal of Ecology, Volume 114, Issue 4, April 2026.
We compared soil organic carbon (SOC) across six savanna–forest boundaries in South Africa. Surprisingly, savanna and forest soils contained comparable SOC stocks. While vegetation change shifted the carbon source from C4‐grasses to C3‐trees, total carbon storage was driven by local soil texture (clay/silt), proving that increasing tree cover does not ...

Do PCEs Adsorb Preferentially on OPC or Calcined Clay?

Journal of the American Ceramic Society, Volume 109, Issue 4, April 2026.
ABSTRACT In multi‐component binders, admixtures such as polycarboxylates (PCEs) may exhibit preferential adsorption onto one component. Hence, for the first time PCE adsorption on ordinary Portland cement (OPC) and calcined clay (CC) in an OPC/CC blend was quantified by separating the OPC and CC particles from the hydrated cement employing a ...
