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 ...

Amapari Marker Band Metal‐Enrichments: Potential Mechanisms and Implications for Surface and Subsurface Water and Weathering in Gale Crater

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract NASA's Curiosity rover is exploring a 5 km tall sedimentary mound that is hypothesized to record the transition from a warm and wet (phyllosilicate‐rich) to a cold and drier (sulfate‐rich) Mars. Evidence of magnesium sulfate‐bearing rock has shown that Curiosity has crossed through this phyllosilicate‐sulfate transition.

Neighboring Ridgetops With Distinct Weathering Drivers Have Strikingly Similar Saprolite Chemical Weathering

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Chemical weathering, and the subsequent porosity it generates controls soil development, water cycling, and nutrient availability. However, predicting spatial variability in chemical weathering remains challenging due to complex interactions between dominant drivers including climate, topography, water cycling, and vegetation dynamics.

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.

Tracking via Coccolith Assemblages the East Asian Monsoon and Carbonate Production in the South China Sea During Termination II and Marine Isotope Stage 5e

Paleoceanography and Paleoclimatology, Volume 41, Issue 4, April 2026.
Abstract Coccolith assemblages from the last 158 kyr, encompassing Marine Isotope Stage (MIS) 5e (130–116 kyr) and preceding deglaciation (Termination II; T‐II), offer important insights about current and future climate changes. The South China Sea (SCS) represents a perfect area for reconstructing past East Asian Monsoon (EAM) dynamics thanks to its ...

LamelODF: a MATLAB‐based toolbox for orientation distribution analysis and mapping of lamellar minerals for laboratory and synchrotron X‐ray diffractometers

Journal of Applied Crystallography, Volume 59, Issue 2, Page 648-661, April 2026.
LamelODF is a MATLAB‐based toolbox aimed at simplifying the automated extraction of orientation distribution functions from 2D X‐ray diffraction data of lamellar minerals in transmission mode. It accommodates both laboratory and synchrotron data formats, providing an integrated pipeline from raw data to spatially resolved textural maps, enabling robust

Eye makeup in Northwestern Iran at the time of the Assyrian Empire: a new kohl recipe based on manganese and graphite from Kani Koter (Iron Age III)

Archaeometry, Volume 68, Issue S1, Page S7-S21, April 2026.
Abstract Kohl was ubiquitous in ancient Egypt and the Middle East, and routinely included among the toiletries deposited in burials. For Egypt, kohl recipes are increasingly well‐studied and known to use a range of inorganic and organic ingredients. Although these are often lead‐based, manganese‐ and silicon‐rich compounds are also attested.

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 ...

Journal of Food Safety, Volume 46, Issue 2, April 2026.
This study evaluated the antimicrobial activity of 11 natural agents against eight STEC serotypes by determining their MIC and MBC at different pH and temperature conditions. Five agents demonstrating the strongest inhibitory activity in vitro were then tested at various concentrations in beef burgers inoculated with Escherichia coli O157 and stored ...
