Longevity and Reactivation of Intracontinental Walled Basins: Thermochronologic Evidence From Western Mongolia

open access: yesBasin Research, Volume 38, Issue 4, July–August 2026.
Permian–Jurassic tectonism produced cooling ages preserved in Mesozoic strata of the Dzereg and Dariv basins. Thermal modeling indicates mid‐Cretaceous and late Cenozoic basin inversion and cooling synchronous with bounding‐range exhumation, supporting a long‐lived source‐to‐sink relationship and persistent inherited relief since the Jurassic ...

Thermal and Structural Reconstruction of an Eroded Foreland Basin: Central Appalachian Basin, USA

open access: yesBasin Research, Volume 38, Issue 4, July–August 2026.
New low‐temperature thermochronology and modelling reveal a complex thermal history for the central Appalachian Basin. Results indicate Carboniferous exhumation of the fold‐thrust belt and Mesozoic heating in the foredeep linked to the Rome Trough. Deeply buried Devonian source rocks were consequently pushed past the peak oil and gas windows.

Subduction Initiation and Early Subduction Zone Development: Insights From the P–T–t Path of the Bay of Islands Metamorphic Sole

open access: yesJournal of Metamorphic Geology, Volume 44, Issue 7, Page 510-536, August 2026.
ABSTRACT The processes involved during subduction initiation (SI) remain poorly constrained, in part due to the rarity of geological archives. Ophiolites and their underlying metamorphic soles are thought to form during subduction zone infancy and may thus provide critical constraints. Metamorphic soles are derived from oceanic crust of the lower plate

The Ames impact structure, Oklahoma: New radioisotopic constraints and implications for North American impact chronology

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 8, Page 2103-2139, August 2026.
Abstract The Ames impact structure (Oklahoma) is thought to have formed during the Ordovician Meteor Event, based on conodont biostratigraphy of its crater fill. Here, U–Pb zircon dates from its impact‐melt portion, conducted using secondary ion mass spectrometry and laser ablation–inductively coupled plasma–mass spectrometry (n = 37 spots), yield a ...

Potassium isotopic compositions and exposure ages of evolved and silica‐rich achondrites

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 8, Page 2140-2162, August 2026.
Abstract Some of the oldest igneous rocks in the Solar System include evolved and silica‐rich achondrites that originate from parent bodies less than 1000 km in diameter, referred to as planetesimals. While Earth was initially in a molten state and required continental crust formation and plate tectonics to generate andesite bulk compositions, evolved ...
