Geochemistry, Geophysics, GeosystemsIn convergent high‐pressure settings dominated by dry mafic rocks, strain has been proposed to be predominantly localized in eclogite. However, the processes initiating strain localization, accommodating strain and rheological consequences remain to be ...

Earth and Planetary Science Letters, 1979 Abstract The eclogite fragments of the Tauern Window formed at pressures around 20 kbar and temperatures in the region 600–650°C; these pressures are higher by 10–12 kbar than those experienced by the units now surrounding the eclogite-bearing zone. The eclogites probably formed in a subduction zone prior to the main Austroalpine collision: downward ...

Sound Velocities of Stishovite at Simultaneous High Pressure and High Temperature Suggest an Eclogite‐Rich Layer Beneath the Hawaii Hotspot [PDF]
Geophysical Research LettersCompressional and shear wave velocities of polycrystalline stishovite (SiO2) have been measured at simultaneous high pressures and temperatures up to 14.5 GPa and 800°C. By fitting velocities to the finite strain equations, the elastic moduli and density

O in omphacite of quartz and coesite eclogite from Erzgebirge and Fichtelgebirge, Germany [PDF]
, 2022 Major and trace elements in omphacite, including hydrogen, were determined in eclogites from two Variscan basement complexes in Germany: Erzgebirge (EG) and Fichtelgebirge (FG).

Partial melting of amphibole–clinozoisite eclogite at the pressure maximum (eclogite type locality, Eastern Alps, Austria) [PDF]
, 2023 Pristine amphibole–clinozoisite eclogite from within the eclogite type locality (Hohl, Koralpe) of the Eastern Alps in Austria preserves centimetre-thick, concordant, laterally continuous leucocratic segregations of coarse-grained (up to ∼ 1 cm grain ...

High-pressure veins in eclogite from New Caledonia and their significance for fluid migration in subduction zones [PDF]
, 2015 This paper describes the petrology and geochemistry of high-pressure veins and associated metasomatic selvages that are hosted by eclogite in the Pouébo Eclogite Melange of northern New Caledonia.

Neoproterozoic Eclogite-to Granulite-Facies Transition in the Ubendian Belt, Tanzania, and the Timescale of Continental Collision [PDF]
, 2022 In collision-type orogens, where high-pressure and ultrahigh-pressure (HP-UHP) metamorphism usually occurs, deeply subducted continental slabs with eclogitized mafic rocks often undergo recrystallization/overprinting with various geothermal gradients ...

Zircon inclusion suite analysis of the Ashe Metamorphic Suite, NC: implications for exhumation history of eclogite [PDF]
, 2006 Previous research suggests the Ashe Metamorphic Suite (AMS) in northwestern North Carolina contains individual eclogite blocks which were entrained within an amphibolite-facies accretionary wedge.

Thermal equation of state of the main minerals of eclogite: Constraining the density evolution of eclogite during the delamination process in Tibet [PDF]
Solid Earth, 2022 Tibet, which is characterized by collisional orogens, has undergone the process of delamination or convective removal. The lower crust and mantle lithosphere appear to have been removed through delamination during orogenic development.
