Trace element geochemistry of the Early to Late Cretaceous deposits of the Grajcarek thrust-sheets : a palaeoenvironmental approach (Małe Pieniny Mts., Pieniny Klippen Belt, Poland) [PDF]

open access: yes, 2012
The chemical composition of the Cretaceous deposits of the Grajcarek thrust-sheets (Pieniny Klippen Belt, Poland) has been investigated to provide information on palaeoenvironment and provenance of pelagic and turbiditic particles.

Geology, petrography, geochemistry and petrogenesis of intermediate subvolcanic units in the south of Zahedan, Sistan and Baluchestan province, Iran

open access: yesJournal of Economic Geology, 2022
The study area is located 12 km south of Zahedan city, Sistan and Baluchistan province. Rock units in this area include a series of slightly altered flysch facies units with Eocene age, subvolcanic rocks and basic to intermediate dikes with probably ...

Evidence for Late Triassic crustal suturing of the Central and Southern Pamir

open access: yesJournal of Asian Earth Sciences: X, 2020
The timing of closure of the Paleotethys and Rushan ocean basins and suturing of Gondwanan crustal fragments in the Pamir is not well resolved. Whereas the Central Pamir terrane is generally interpreted to have collided with the Northern Pamir terrane at

Magnetic Structure and its Tectonic Implication Around Longmenshan Fault Zone Revealed by EMAG2v3

open access: yesFrontiers in Earth Science, 2022
The formation of magnetic minerals is bound up with the tectonic evolution history, whereupon the distribution of magnetic anomalies has great meanings for regional tectonics.

Vertical crustal motions across Eastern Tibet revealed by topography-dependent seismic tomography

open access: yesScientific Reports, 2017
Using a topography-dependent tomographic scheme, the seismic velocity structure of the Eastern Tibetan Plateau, including the uplifted Longmenshan (LMS) orogenic belt, is accurately imaged in spite of the extreme topographic relief in the LMS region and ...

Subparallel thrust and normal faulting in Albania and the roles of gravitational potential energy and rheology contrasts in mountain belts [PDF]

open access: yes, 2009
The active tectonics of Albania and surrounding regions, on the eastern margin of the Adriatic Sea, is characterized by subparallel thrust and normal faulting which, we suggest, is likely to be related to gravitational potential energy contrasts between ...

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.

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 ...
