Stratigraphy of a flysch succession: the Ordovician of W Nithsdale, SW Scotland

open access: yes, 1982
A thick Ordovician marine flysch succession including greywackes, conglomer- ates, siltstones and shales occurs in West Nithsdale in the Northern belt of the Southern Uplands.

Provenance of synorogenic deposits of the Upper Cretaceous–Lower Palaeogene Jarmuta–Proč Formation (Pieniny Klippen Belt, Western Carpathians)

open access: yesGeologica Carpathica, 2019
The Pieniny Klippen Belt contains thickening and coarsening upwards synorogenic sedimentary successions witnessing the collision of the Oravic ribbon continent with the Central Carpathian orogenic wedge after the closure of the Vahic Ocean in the Late ...

Long‐Term Increases in Ca2+, Mg2+, and SO42− Concentrations in the Kolyma River (1980–2022) Due To Yedoma Degradation

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 2, February 2026.
Abstract Permafrost degradation under a warming climate has altered hydrological and biogeochemical processes across the Arctic. Although increasing fluxes of weathering‐derived ions (e.g., Ca2+, Mg2+, and SO42−) have been reported in Arctic rivers, the underlying mechanisms and hotspots within basins remain poorly understood due to limited analysis of

Early Cretaceous–Late Miocene Basin–Mountains Pattern in the Northeastern Margin of the Tibetan Plateau, NW China: Evidence From Detrital Zircon Chronology in the Lanzhou Basin

open access: yesGeological Journal, Volume 61, Issue 1, Page 127-145, January 2026.
Using DZmix and DZstats models, we quantified the contributions of potential sources of the Lanzhou basin. Our findings indicate that the Cenozoic cooling and denudation signals primarily originated from Qilian and West Qinling, which were the main sediment sources.

Burial diagenesis, organic maturation and tectonic loading in the French subalpine chains, S.E. France [PDF]

open access: yes, 1992
The French Subalpine Chains of southeastern France lie on the western edge of the Western Alps. The area is the foreland fold/thrust belt to the main orogenic hinterland to the east.

Structure and tectonic significance of deformed medial Ordovician flysch and melange between Albany and Saratoga Lake and in the central Hudson Valley, New York

open access: yes, 1994
The belt of medial Ordovician deformed flysch west of the traditionally defined Taconic boundary thrust was investigated by detailed mapping in the Capital District, from Albany to Saratoga Lake, and large scale compilation of the central Hudson Valley ...

open access: yesGeologija, 2007
Geologic section along the motorway from Kozina to Koper in totality exposed geologic structure of the border belt between Adriatic-Apulian foreland and Dinarides that was formed by subthrusting of Adriatic-Apulian foreland (Istria, Friuli) underneath ...

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

open access: yesGeochemistry, 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.

First Evidence of Hercynian Lower Carboniferous Flyschoid Deep-Water Sediments in the Lycian Nappes, Southwestern Turkey

open access: yesGeologia Croatica, 2010
For the first time. a deep-water Lower Carbon iferous siliciclasticturbidite-olistostrome unit with many lydites (partly distally turbiditic) can be dated in the Incirbeleni Formation of the Tavas Nappe (Lycian nappes) in southwestern Turkey.

Restoring the Missing Late Cretaceous Arc of Iran

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract Persistent arc magmatism archives fluid transport and mantle partial melting in subduction zones. However, arc magmatism often exhibits different magmatic records along the strike, as seen in the Tethyan orogenic belt. During Neo‐Tethys subduction under Iran, there was pulsed arc magmatism with Middle Jurassic and Eocene magmatic flare‐ups ...
