Chromitite deposits of Turkey in Tethyan ophiolites

open access: yes, 2019
Some parts of the Tethyan ophiolites of Alpine-Himalayan suture belt are located within Turkey. The Tethyan belt splits into two branches in Turkey. The northern branch follows the İzmir-Ankara-Erzincan Zone, while the southern branch extends along the ...

Transect through the Vardar Mega Suture Zone [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva
In this contribution, we present the field guide that accompanies the post‐meeting excursion FT4 of the 17th EGU Émile Argand Conference on Alpine Geological Studies. Tectonic maps of Serbia are dominated by broad, chiefly NNW–SSE belts of ophiolitic and

The Impact of Double Subduction on Plate Velocity and Euler Pole Shifts: Insights From Spherical Subduction Models

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Same‐dip double subduction (SDDS), in which two parallel slabs dip in the same direction, has been linked to accelerated plate motion in both modern and ancient convergent systems, such as the Late Cretaceous Africa–Eurasia system. Yet a systematic framework for quantifying how SDDS alters plate kinematics in a large‐scale spherical geometry ...

PETROGRAPHY AND MINERALOGY OF RETROGRADE METAPERIDOTITES FROM ALAG KHADNY ACCRETIONARY WEDGE (SW MONGOLIA): FLUID MODIFICATION IN SUPRASUBDUCTION ZONE

open access: yesГеодинамика и тектонофизика, 2017
The Main Mongolian Lineament (MML) separates northern “Caledonian” tectonic province from southern “Hercynian” in SW part of Mongolia of the Central Asian Orogenic Belt (CAOB). The position of Eastern part of MML is widely discussed at recent time, since,

Provenance Constraints on Early India–Asia Collision: Evidence From the Late Cretaceous–Early Cenozoic Sulaiman–Katawaz Basin Fill

open access: yesBasin Research, Volume 38, Issue 5, September‐October 2026.
Integrated detrital zircon U–Pb, Nd–Sr isotopes and thermochronology record western Indian‐margin provenance reorganisation. Late Cretaceous–Palaeocene sediment supply was Indian‐affinity; Asian‐affinity input appeared across the Palaeocene–Eocene transition (~56.5–54.7 Ma), suggesting India–Asia collision was underway, while mixed provenance persisted

The Alpine Corsica ophiolites from the Inzecca Vally and the Pineto Massif

open access: yes, 2004
The Northern Apennines and the Alpine Corsica are characterized by well preserved examples of Jurassic ophiolite sequences and their related sedimentary cover. These ophiolite sequences are considered remnants of the Ligure-Piemontesedomain, i.e. part of

Composition of parental basaltic magma in ophiolites

open access: yes, 1980
In the past it has been assumed that the parental basaltic magma in ophiolites is subalkaline tholeiitic because so many of their lavas are compositionaly similar to midocean- ridge basalts.

Emplacement of Cuban Ophiolites

open access: yesGeologica Acta, 2005
According to their lithological and structural characteristics, three ophiolite bearing structural units are recognized in Cuba: 1) The Northern Ophiolitic Belt, a complex mélange that stretches more than 1000 km along the island; 2) The metamorphic ...

“Hidden” boninitic magmatism in the Zagros ophiolites. A Comparison with the Albanide-Hellenide Ophiolites.

open access: yes, 2014
Ophiolites surfacing along the Main Zagros Thrust Zone (MZTZ) mark the suture zone between the Arabian and Sanandaj-Sirjan continental blocks. They represent a portion of the southern Neo-Tethyan oceanic lithosphere, which originally existed between the ...
