Redox state of subducted sediments controls porphyry copper mineralization along the Tethyan belt [PDF]

open access: yesNature Communications
The Tethyan orogenic belt hosts numerous world-class porphyry copper deposits, with most forming during the Cenozoic continental collision and fewer during earlier Mesozoic subduction.

Early Late Triassic retro-foreland basin in response to flat subduction of the Paleo-Tethyan oceanic plate, SE Tibet

open access: yesFrontiers in Earth Science, 2022
Syn-subduction basins bear significant implications to understand tectonic evolution of any fossil subduction zone. The late Paleozoic to early Mesozoic (Paleo-Tethyan) tectonics of the eastern and southeastern Tibetan Plateau (i.e., the Sanjiang ...

Detrital zircon U–Pb geochronology and fluvial basin evolution of the Liuqu Conglomerate within the Yarlung Zangbo Suture Zone: A critical geochronometer for the collision tectonics of the Tibetan-Himalayan Orogenic Belt

open access: yesGeosystems and Geoenvironment, 2023
We present new U-Pb detrital zircon ages, depositional history and tectonic model for the Liuqu Conglomerate (LQC) in southern Tibet that represents a critical geochronometer for the collision history of the Tibetan-Himalayan Orogenic Belt.

Late Cenozoic Evolution and Present Tectonic Setting of the Aegean–Hellenic Arc

open access: yesGeosciences, 2022
The Aegean–Hellenic arc is a deformed sector of a long heterogeneous orogenic system (Tethyan belt), constituted by an inner old metamorphic crystalline core flanked by younger chains of European and African affinity, running from the Anatolian to the ...

Metallogeny in the Bangong–Nujiang belt, central Tibet, China: A review

open access: yesFrontiers in Earth Science, 2023
The Bangong–Nujiang metallogenic belt consists of scattered Tethyan oceanic blocks, mainly distributed underneath the margins of the Qiangtang and Lhasa terranes in central Tibet.

Petrogenesis and Geodynamic Implications of Late Triassic Mogetong Adakitic Pluton in East Kunlun Orogen, Northern Tibet: Constraints from Zircon U–Pb–Hf Isotopes and Whole-Rock Geochemistry

open access: yesFrontiers in Earth Science, 2022
Adakites or adakitic rocks usually show special geochemical signatures and are petrological probes to reveal the tectono–magmatic evolutionary history of paleo–orogenic belts. Here, we present a comprehensive study on the zircon U–Pb geochronology, whole-

The deformation and mechanisms of the Zhangbaling tectonic belt during Indosinian to early Yanshanian: Implications for the relationship with the Tan-Lu Fault Zone

open access: yesSolid Earth Sciences, 2021
The Zhangbaling tectonic belt is located in the middle segment of Dabie-Sulu Orogenic Belt and in the eastern part of the main segment of the Tan-Lu Fault Zone (TLFZ).

Temperature condition, sulfidation state, and gold formation mechanism of the Atash- Anbar polymetallic deposit (south Qazvin) based on mineralization, alteration and chemistry of ore minerals [PDF]

open access: yesپترولوژی, 2022
The NW-trending Urumieh-Dokhtar Magmatic Belt (UDMA) in the central-western Iran is a part of the Eastern Tethyan orogenic belt (Deng et al., 2018) and over past decades, it has become one of the most significant polymetallic (Au-Cu-Fe-Pb-Zn) provinces ...

Natural observations of subduction initiation: Implications for the geodynamic evolution of the Paleo-Asian Ocean

open access: yesGeosystems and Geoenvironment, 2022
Initiation of new subduction zones is an integral part of Earth's plate tectonics regime. It is generally accepted that the negative buoyancy of sufficiently old oceanic lithosphere provides the primary driving force for subduction initiation.

Geochemistry and tectonomagmatism setting of gabbroic bodies in South of Ramsar, West of Mazandaran Province: Evidence for Oceanic Island magmatism [PDF]

open access: yesپترولوژی, 2022
IntroductionIn the study area, in Guilan and Mazandaran provinces and the northern heights of the Alborz mountain range in northern Iran, several gabbroic and ultramafic assemblages of different ages have been reported.
