Interpreting Europium Anomalies in Zircon: The Importance of Source Redox
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

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
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
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
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 ...

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 ...
