Interpreting Europium Anomalies in Zircon: The Importance of Source Redox

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.
Abstract The sources of granitoids are variably oxidized due to the diversity of environments in which they form. This environmental and consequent chemical variability leads to differences in mineral assemblages, proportions, and compositions of ferric and ferrous iron‐bearing phases in these sources and in the resultant granitoids. Accessory minerals

Classification and origin of pore–throat systems in tight sandstone reservoirs: a case study of the Xujiahe Formation in the Northeastern Sichuan Basin, China

open access: yesFrontiers in Earth Science
IntroductionThe reservoirs of the Xujiahe Formation in the northeastern Sichuan Basin have complex rock components, strong pore–throat inhomogeneity, and large differences in the production capacity between wells, and the mechanism of high-quality pore ...

Constraints on Magma Pressure Distribution During Long Range Lateral Propagation of Giant Radial Dyke Swarms

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract Giant dyke swarms are important but enigmatic components of magma transport in the Earth and terrestrial planets. Although widely documented on Earth, Venus, and Mars as extending laterally for 100–1,000 s of kilometers from their magma sources, the reasons for this extraordinary lateral propagation are not known.

The evolution of reproduction in Ediacaran–Cambrian metazoans

open access: yesBiological Reviews, Volume 100, Issue 5, Page 2084-2098, October 2025.
ABSTRACT The evolution of reproductive style is a fundamental aspect of metazoan life history but has not been explored holistically through the Ediacaran–Cambrian rise of metazoans. Recent molecular clock analyses based on only unequivocal metazoan fossil calibrations suggest that Porifera were present by at least 590 million years ago (Ma), all major

Plastics in dermatology: A review and solutions

open access: yesJournal of the European Academy of Dermatology and Venereology, Volume 39, Issue 10, Page 1715-1724, October 2025.
This review explores the environmental and health impacts of plastics, particularly microplastics in dermatological products. It discusses the plastic life cycle, routes of exposure, health risks and provides science‐based recommendations to reduce plastic use in dermatology.

A Paleotectonic Atlas of the African Plate: Permian to Recent

open access: yesJournal of Petroleum Geology, Volume 48, Issue 4, Page 231-279, October 2025.
ABSTRACT The fragmentary release of petroleum data defining the deep structure and stratigraphy of African basins has been integrated with existing literature to compile 19 tectonic maps over key geological intervals from Permian to Recent times. African plate margins range in their age of opening from Late Triassic (off Lebanon), through Early/Middle ...

Resolving allogenic forcings on shallow‐marine sedimentary archives of the Taiwan Western Foreland Basin

open access: yesSedimentology, Volume 72, Issue 6, Page 1755-1785, October 2025.
ABSTRACT An investigation of allogenic forcings on shallow‐marine strata of the Miocene–Pliocene Kueichulin Formation, Taiwan Western Foreland Basin, reveals that shifts in palaeoenvironments were strongly controlled by: (1) orogenesis and basin subsidence, (2) precession‐driven hydroclimate and (3) obliquity‐driven atmospheric and ocean circulation ...
