Geochronological Constraints on Diachronous Post‐Collisional Slab Breakoff Along the Paleo‐Tethyan Sutures

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract The slab breakoff model is a preferred geodynamic interpretation for post‐collisional exhumation and associated magmatic flare‐ups. In this study, rutile U–Pb dating of retrograde eclogites revealed distinct stages of exhumation along the Paleo‐Tethyan sutures in southwest China. The studied samples yielded ages of 246.7 ± 8.5 and 239.7 ± 14.0

Chromitite deposits of Ufaley ultramafic massif (South Urals)

open access: yesGeoresursy
Data on the morphology, composition, textural and structural features of chromite deposits of the Ufaley ultramafic massif are presented. The mineralogical and compositional features of the host ultramafic rocks allow us to interpret them as depleted ...

U-Pb zircon ages from the Spontang Ophiolite, Ladakh Himalaya

open access: yes, 2001
The Spontang Ophiolite in the Ladakh Himalaya consist of a thrust sheet of upper mantle and oceanic crustal rocks obducted onto the northern passive continental margin of India during the late Cretaceous. Precise isotopic ages of Himalayan ophiolites are

The tectonic evolution of the Hatay ophiolite of southeast Turkey [PDF]

open access: yes, 2005
A combination of palaeomagnetic and structural analyses have been used to constrain rotations in the Hatay (Kizildag) ophiolite of southeast Turkey in the eastern Mediterranean region and to produce a tectonic model for its evolution.
