Depositional Interplay Between the Ancestral Rocky Mountains and Ouachita–Marathon–Sonora Orogenies: Insights From Provenance Records in the Late Palaeozoic Marfa Basin, West Texas, USA

Basin Research, Volume 38, Issue 2, March–April 2026.
Provenance records from the late Palaeozoic Marfa Basin in West Texas reveal the transition from the Ancestral Rocky Mountains to the Ouachita–Marathon–Sonora orogenies during the early Permian in SW Laurentia. ABSTRACT The Marfa Basin in West Texas is a late Palaeozoic synorogenic depocenter associated with regional deformation linked to the Ancestral

Crustal Structure of Laurentia and Peri‐Gondwanan Terranes Beneath Ireland and Britain and Comparison With Eastern North America

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The Appalachian‐Caledonian orogen was built during the Paleozoic by accretion of peri‐Gondwanan terranes onto Laurentia, culminating in the formation of Pangea. During the Mesozoic, Pangea broke apart, displacing one section of the belt to eastern North America and another to northwestern Europe.

Gondwanan Origin of Bark and Ambrosia Beetles and Their Rapid Worldwide Diversification During the Cretaceous

Journal of Biogeography, Volume 53, Issue 2, February 2026.
ABSTRACT Aim It is not trivial to estimate the relative contributions of dispersal, vicariance, and range contraction in explaining the present‐day distribution of ancient clades. In this study, we aim to infer the historical biogeography of bark and ambrosia beetles using a genus‐level time‐calibrated molecular phylogeny that encompasses 70% of all ...

Freshwater amphibians and squamates from Villeveyrac (lower Campanian; Hérault, France): palaeodiversity, palaeoenvironment and implications for the Late Cretaceous palaeobiogeography of the European herpetofauna

Papers in Palaeontology, Volume 12, Issue 1, January/February 2026.
Abstract The Late Cretaceous witnessed numerous transgression–regression sequences and the onset of a global cooling phase at the start of the Campanian. In the European archipelago, these environmental changes, combined with active plate tectonics, facilitated the formation of ephemeral land bridges that served as dispersal routes for a variety of ...

Provenance Reassessment of Eocene Turbidites, New Caledonia: Inferences for Obduction Models

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract Provenance of pre‐obduction Eocene turbidites from New Caledonia is used to better constrain their geodynamic context and inform debate on subduction polarity. Chemical compositions of detrital clinopyroxenes in arenites are compared against potential sources.

A look at the 1.8-2.2 Ga zircon distribution as a paleogeographic and provenance indicator for peri-Gondwanan terranes

, 2022
The Paleoproterozoic orogenies are among the most significant crustal growth events recorded in Western Gondwana, as depicted by their strong detrital zircon signature into the Gondwanan and peri-Gondwanan sediments. Indeed, the Neoproterozoic–Cambrian sediments of peri-Gondwanan terranes, particularly those in Iberia, Meguma, Avalonia, and Ganderia ...

Crustal Architecture and Low‐Temperature Geochronology of an Apparent Cycladic Tectonic Window (NE Attica, Greece): Insights Into Imbrication in Subduction Settings

Tectonics, Volume 44, Issue 11, November 2025.
Abstract Understanding the timing and configuration of tectonic nappes in collapsed orogens is integral to reconstructing its geodynamic evolution. Northeastern Attica lies between bivergent Miocene detachment systems and has historically been interpreted as a tectonic window exposing the lowest nappe of the Hellenides, the Basal Unit.

Tracing the biogeographic history of the world's most isolated insular floras

Journal of Systematics and Evolution, Volume 63, Issue 4, Page 952-973, July 2025.
We inferred the spatio–temporal colonization histories of seven vascular plant lineages (Acaena magellanica, Austroblechnum penna‐marina, Azorella selago, Colobanthus kerguelensis, Notogrammitis crassior, Polystichum marionense, Pringlea antiscorbutica) using phylogenetic, divergence time estimation, and Bayesian Island Biogeographic analyses.

The tectonic significance of peri-Gondwanan Late Neoproterozoic-Early Palaeozoic felsic peraluminous magmatism

Earth-Science Reviews
[EN] We provide a thorough review of the literature on peraluminous magmatism of Late Neoproterozoic and Early Palaeozoic (mostly Late Cambrian-Middle Ordovician) age cropping out in many places around the world (SW South Africa, NE Patagonia, NW Argentina, Colombia, SE Mexico and Guatemala, the European Variscan Massifs and from Turkey to northern ...
