Silurian post-orogenic volcanic rocks of the South Kunlun Belt, NW China: links to the Proto- to Paleo-Tethyan tectonic transition

International Geology Review, 2021
Newly discovered early Palaeozoic intraplate volcanic rocks within the southern Kunlun Orogen provide an opportunity to examine the middle to late Silurian tectonic setting of this area. This study presents new whole-rock geochemical and zircon U–Pb geochronological and Lu–Hf isotope data for the Silurian volcanic rocks of the Wanbaogou area, South ...

RHAETIAN FORAMINIFERS FROM THE WESTERN BLACK SEA SHELF: NEW EVIDENCE FOR HETEROZOAN CARBONATE FACTORIES IN THE PALAEOTETHYS

Rivista Italiana di Paleontologia e Stratigrafia, 2021
The North Dobrogean Orogen (NDO) is a NW-SE trending fold-and-thrust belt in the eastern foreland of the Alpine Carpathian Orogen, palaeogeographically representing the westernmost segment of the Palaeotethys-issued Cimmeride Orogenic System.

Geochemistry and tectonic setting of extrusive rocks in the southeast of Maimeh, northwest of Isfahan

Journal of Economic Geology, 2021
Introduction The studied area is situated 15 km away from the southwest of Maimeh at the western part of Urumieh-Dokhtar magmatic arc. This zone is a part of the Zagros orogenic belt formed due to the subduction of the Neo-Tethyan oceanic crust under ...

Saheb Granitoid Batholith, North of Kurdistan: An Evidence of Cretaceous- Paleocene Magmatism in the Sanandaj-Sirjan Zone

Journal of Economic Geology, 2020
Introduction The Iranian plateau is part of the Alpine-Himalayan orogenic belt, which consists of several continental fragments separated from each other by major boundary faults and/or ophiolitic suture zones (Gansser, 1981).

Provenance of Middle Triassic sediments in the Southern Youjiang Basin: Insights from detrital zircon geochronology and tourmaline geochemistry

The Depositional Record, Volume 12, Issue 4, September 2026.
Middle Triassic turbidites in the Youjiang Basin were chiefly derived from a Late Palaeozoic continental arc along the southeastern South China Block, as revealed by detrital zircon U–Pb geochronology and tourmaline geochemistry, supporting a tectonic model driven by Paleo‐Pacific subduction rather than Paleo‐Tethyan closure.

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

Geochemistry, 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
