Paleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.Abstract The Cretaceous–Paleogene boundary (∼66 million years ago) represents the most recent mass extinction event when an estimated 75% of all species became extinct, including all non‐avian dinosaurs. Here we focus on the stable carbon isotope (δ13C) analysis of coal and coaly sediments across the terrestrial K/Pg boundary from 10 sites, between 42 ...

Tectonics, Volume 45, Issue 7, July 2026.Abstract The accretion of allochthonous provinces, derived from oceanic plates, has traditionally been considered an important contributor to continental growth. However, increasing evidence shows that some oceanic terranes (e.g., island arcs) are not “exotic,” as suggested by the presence of continental‐derived sedimentary provenance.

In Situ U–Pb Geochronology of Hydrothermal Xenotime and Monazite to Date Gold Mineralization in the Northern Capricorn Orogen, Western Australia [PDF]
, 2018 In situ SHRIMP U-Pb geochronology of xenotime and monazite is a powerful method for dating hydrothermal gold mineralization. This method has been applied to the northern Capricorn Orogen of Western Australia, providing a new geological framework that ...

Tectonics, Volume 45, Issue 7, July 2026.Abstract Transverse zones (TZs) in fold‐and‐thrust belts typically comprise strike‐slip to transpressional faults and related folds, oriented sub‐parallel to the regional shortening direction. These zones are typically associated with inherited faults or lateral stratigraphic changes, which promote strain partitioning, stress rotation, and kinematic ...

The Origin of Carbonate Magmas Predating and Accompanying Main‐Phase LIPs Eruptions
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.Abstract Some large igneous provinces (LIPs) are associated with precursory carbonatite eruptions. Models for precursory carbonatites invoking partial melting of a carbonate metasomatized lithosphere appear implausible, given the long time needed for heat conduction from the plume head.

Late Holocene moisture variability in Arctic Alaska from chitin δ18O
Boreas, Volume 55, Issue 3, Page 751-767, July 2026.Amplified warming in the Arctic has resulted in reduced sea‐ice extent, which can impact regional climate dynamics. Elucidating past moisture variability in response to changing temperatures and sea‐ice conditions can offer insight into how anthropogenic climate change may impact Arctic areas such as the Alaskan North Slope in the future. We contribute

Boreas, Volume 55, Issue 3, Page 835-845, July 2026.Loess–palaeosol sequences (LPS) represent one of the most important continental archives of late Quaternary environmental change in Europe. Establishing reliable chronologies is essential for reconstructing dust dynamics and for correlating regional loess stratigraphies. In this study, we present the first systematically derived mass accumulation rate (

, 2009 A compelling new model for caldera evolution challenges the standard depiction of large-scale volcanism. Here, I test these competing models by establishing the temporal and chemical relationship between ignimbrite and potential cogenetic plutons related
