The Composition–Structure Relationship and the Formation of Fly Ash Skeletal-Dendritic Ferrospheres

Molecules
Ferrospheres (FSs) are a microspherical component of fly ash from pulverized coal combustion. The wide variations in chemical and phase composition, morphology, and the spherical design of FSs suggest their use as functional materials capable of ...

Climate conditions on the South‐Iberian Palaeomargin during the latest Pliensbachian to early Toarcian: A mineralogical and geochemical study from hemipelagic deposits

Sedimentology, EarlyView.
ABSTRACT The integrated analysis of lithofacies, mineralogy and geochemistry of the hemipelagic marine succession exposed in La Cerradura section (South‐Iberian Palaeomargin) provides new information to characterise the palaeoenvironmental conditions during the latest Pliensbachian to early Toarcian, including the Jenkyns Event.

Comprehensive Investigations on the Effects of Heat on “Illite–Zeolites–Geo-Polymers–Sand” Composites: Evolutions of Crystalline Structures, Elemental Distributions and Si/Al Environments

Ceramics
This research constitutes a novel experimental approach to valorizing an industrial by-product: the ‘brick’. Studies put emphasis on the importance of detailed structural characterization of brickminerals and their chemical evolution upon heating ...

Loess Studies in Aotearoa New Zealand

New 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.

Nutrition Status of Trees on Spoil Heaps After Coal Mining Can Be Inferred From Seasonal Dynamics of Foliar Nutrient Concentrations

Land Degradation &Development, Volume 37, Issue 7, Page 2583-2596, 30 April 2026.
ABSTRACT A stable vegetation cover on given habitat conditions can be one of the possible requirements for post‐mining sites, as it can prevent erosion and dustiness of these anthropogenic surfaces and bring several practical future benefits, such as biomass production and microclimate improvement.

ENSO‐Mediated Linkage Between the East Asian Summer Monsoon and Cordilleran Ice Sheet Discharge During MIS 3

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Understanding the mechanisms linking low‐latitude monsoon variability and high‐latitude ice‐sheet discharge is critical for elucidating past atmospheric teleconnections, yet direct evidence for such linkages during the last glacial period remains limited. Here we present a high‐resolution terrigenous input record from the South China Sea (SCS)

Constraining the Relative Chronology of Repeated Large Earthquakes in the Longmen Shan Thrust Belt, Eastern Tibetan Plateau

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The Yingxiu–Beichuan Fault Zone (YBFZ), located in the Longmen Shan Thrust Belt (LSTB) on the eastern Tibetan Plateau, is highly seismically active. However, direct evidence of large earthquakes at depth is scarce. Here, we present rock magnetic, microstructural, and geochemical analyses of four fault zones from the Wenchuan Earthquake Fault ...

Mg isotope fractionation during microbial dolomite formation in the Khor Al‐Adaid sabkha, Qatar

The Depositional Record, Volume 12, Issue 2, April 2026.
Modern sabkha sediments from southern Qatar show ca. 1‰ Ca isotope fractionation between pore water, organic matter and dolomite, supporting microbial mediation. In contrast, minimal Mg isotope fractionation and inorganic‐like dolomite δ26Mg indicate that microbial influence is indirect, expressed through subtle pore water shifts driven by Mg ...

Mott–Schottky Analysis of Archaeological Etruscan Pottery

Electroanalysis, Volume 38, Issue 4, April 2026.
Mott–Schottky plots of the inverse of the square of capacitance versus applied potential is used to study archaeological pottery from the Etruscan site of Pyrgi in Santa Severa (Rome, Italy). The application of Mott–Schottky (MS) analysis to electrochemical impedance data recorded for microparticulate deposits of archaeological ceramic materials is ...
