A re-evaluation of the peak P–T conditions of eclogite-facies metamorphism of the Paleozoic Acatlán Complex (Mexico) reveals deeper subduction [PDF]

Scientific Reports, 2022
Eclogites in the Acatlán Complex, southern Mexico, record the subduction history of the complex. Previous studies indicate that the proto-Acatlán Complex reached

Metamorphic evolution of amphibolite from Proto-Tethys South Altyn orogen and its geological significance [PDF]

Scientific Reports
Medium- to low-grade metamorphic (LP–MP) rocks, though major constituents of collisional orogens, remain less studied than high-to ultrahigh-pressure (HP–UHP) counterparts.

Zircon U–Pb Dating and Lu-Hf Isotope of the Retrograded Eclogite from Chicheng, Northern Hebei Province, China

Shock and Vibration, 2021
We report zircon U–Pb ages and Lu-Hf isotopic data from two sample of the retrograded eclogite in the Chicheng area. Two groups of the metamorphic zircons from the Chicheng retrograded eclogite were identified: group one shows characteristics of ...

Petrology and Tectonic Geophysics of Massive and Foliated Eclogites in the North Qilian Orogenic Belt: Changes in Mineral Composition, Oxygen Fugacity, and Fabric during Exhumation

Adsorption Science & Technology, 2022
The North Qilian orogenic belt is a typical area of “cold” subduction of the early Paleozoic oceanic plate, forming a series of high pressure and low temperature metamorphic rock assemblages. Among them, eclogite is a kind of protolith, which is basaltic

Electrical Conductivity of Eclogitic Omphacite and Garnet at Water-Rich Conditions

Frontiers in Earth Science, 2022
Electrical conductivity of water-rich omphacite and garnet in eclogite was measured at 1 GPa and 200–800°C in a piston cylinder press and by a Solartron-1260 impedance/gain-phase analyzer at 106-1 Hz frequency. The water content of pre-annealed omphacite

Paleo-Tethys subduction and arc-continent collision: Evidence from zircon U-Pb chronology, geochemistry and Sr-Nd-Hf isotopes of eclogites in western Yunnan, bangbing area, southeastern Tibetan Plateau

Frontiers in Earth Science, 2022
The Changning-Menglian suture zone (CMSZ) in the southeastern Tibetan Plateau is a newly discovered HP-UHP metamorphic zone. The eclogites therein are the key evidence constraining the main suture of the Proto- and Paleo-Tethys Ocean in western Yunnan ...

Prograde and retrograde P–T evolution of a Variscan high-temperature eclogite, French Massif Central, Haut-Allier

BSGF - Earth Sciences Bulletin, 2020
The P–T evolution of a mafic eclogite sample from the Haut-Allier was studied in order to constrain the dynamic of the Variscan subduction in the eastern French Massif Central.

Implication of garnet zoning in high pressure- ultrahighpressure eclogite from Changning-Menglian suture zone, Bangbing area, Southeast Tibetan Plateau

Frontiers in Earth Science, 2022
Major and trace element zonation patterns were determined in ultrahigh-pressure eclogite garnets from the Changning-Menglian suture, Bangbing area. Several stages of eclogite metamorphism are recorded by garnet zonation.

Report of a rare, well-preserved lawsonite eclogite (Elekdağ, Central Pontides, Türkiye) [PDF]

European Journal of Mineralogy
Although lawsonite eclogite is predicted from experimental, thermodynamic, and geophysical methods to be common in cold subduction zones, the defining metamorphic assemblage in metabasite (garnet + omphacite + lawsonite) is rare in exhumed subduction ...
