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

open access: yesTectonics, 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.

Toposequences of Forest Soil Properties Between Differently Elevated Igneous and Sedimentary Mountain Ranges

open access: yesEuropean Journal of Soil Science, Volume 76, Issue 6, November–December 2025.
ABSTRACT Soil properties are significantly, but unevenly, conditioned by the landscape relief and/or bedrock. Here, we compare forest soil properties along toposequences between differently elevated areas of denuded Variscan mountain ranges and the alpine‐fold Carpathians in the Czech Republic (Central Europe). Correlating soil properties were selected

The Uplift of Armorica and the Bretonian Movements of the Variscan Orogeny‐New Insights From Detrital Zircons in the Early Carboniferous Terrigenous Rocks of the Laval Basin (Armorican Massif, France)

open access: yesGeochemistry, Geophysics, Geosystems
In the French Armorican Massif, the Bretonian phase of the Variscan orogeny has been defined by the Late Devonian (Famennian‐Frasnian) erosion gap, and the Early Carboniferous (Tournaisian) syntectonic terrigenous deposits of the l’Huisserie formation in

The Upper Palaeozoic pebbly mudstone facies of peninsular Thailand and western Malaysia - Continental margin deposits of Palaeoeurasia [PDF]

open access: yes, 1986
Die devonische bis unterpermlsche Phuket Group in Thailand und deren Äquivalent in Malaysia, die Singha Formation, gehören zum SE-asiatischen "pebbly mudstone Gürtel", welcher sich vom südlichen Tibet bis Sumatra erstreckt. Diese ca.

Precambrian Greenstone Belts of North Baffin Island, Canadian Arctic: Geochronological Constraints on Magmatism and Stratigraphy in the Rae Craton

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.
Abstract Supracrustal greenstone belts of the Rae craton of north Baffin Island have been historically attributed to the Mary River Group (MRG), a key tectonostratigraphic unit of economic significance. Best‐preserved exposures of supracrustal rocks occur within the Eqe Bay Greenstone Belt.

Arc Splitting and Back‐Arc Spreading Evolution: The Control of Slab Dehydration and Melting Processes

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.
Abstract Subduction zones are integral to Earth's deep water cycle, influencing magmatism, lithosphere dynamics and seismicity. They often exhibit development of extensional processes in the upper plate, which may lead to volcanic arc splitting and backarc basin opening.

Receiver function study of the Hellenic subduction zone: imaging crustal thickness variations and the oceanic Moho of the descending African lithosphere [PDF]

open access: yes, 2017
We use data from recently installed broad-band seismographs on the islands of Crete, Gavdos, Santorini, Naxos and Samos in the Hellenic subduction zone to construct receiver function images of the crust and upper mantle from south of Crete into the ...

Triassic Intracontinental Crustal Reworking of the Eastern Tianshan: New Insights From Late Triassic Adakitic and Low‐Sr/Y Granitoids in the Bogda Range

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.
Abstract Continental intraplate magmatism remains a fundamental challenge in Plate Tectonics. Triassic magmatism represents a critical phase in the evolution of the Central Asian Orogenic Belt and continues to provoke debate about its tectonic setting.
