Earthquakes and the Metamorphic Sole of the Tinos Ophiolite, Cyclades, Greece

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract We analyze deformation fabrics, compositions of melts, metamorphic temperatures, and paleopiezometric data beneath the Tsiknias Thrust, Tinos, Greece, which formed part of the plate boundary that, in Late‐Cretaceous time, absorbed convergence between Africa and Europe associated with final closure of the Vardar Ocean.

Patterns and Mechanisms of Melt Distribution in Partially Molten Harzburgite under Hydrostatic Pressure [PDF]

, 2017
Geophysical and geochemical properties of partially molten regions of the Earth’s upper mantle are strongly affected by the distribution of melt. I investigated the mechanisms affecting the 3-dimensional (3D) melt distribution of partially molten ...

Deciphering metasomatic events beneath Mindszentkálla (Bakony-Balaton Highland Volcanic Field, western Pannonian Basin) revealed by single-lithology and composite upper mantle xenoliths

Frontiers in Earth Science, 2022
Single-lithology and composite xenoliths from Mindszentkálla (Bakony-Balaton Highland Volcanic Field) in the Carpathian-Pannonian region record geochemical evolution of the subcontinental lithospheric mantle.

Multistage Evolution and Inheritance in a Magma‐Poor Conjugate Margin: Insights From Serpentinized Peridotites of the Newfoundland Margin (ODP Hole 1277A)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract The nature of mantle sections exhumed at magma‐poor rifted margins remains poorly constrained, largely because direct sampling of mantle in modern passive margins is exceptionally rare. The Iberia–Newfoundland system is unique in providing drilled mantle rocks on both conjugate margins, offering an unprecedented glimpse into mantle ...

Geochemistry and petrogenesis of mantle peridotites from the Nehbandan Ophiolitic complex, Eastern Iran

, 2009
Ophiolitic exposures from the East and Northeast of Nehbandan. Eastern Iran, are remnants of a Cretaceous oceanic basin between Lui and Afghan continental blocks. Based on petrographic studies, they contain harzburgite.

Geophysical Hunt for Chromite in Ophiolite [PDF]

International Journal of Economic and Environment Geology, 2013
Ophiolite of Oman are famous world over, and are favorite for exploring chromite, which is a source of chromium that is used widely in steel, nichrome, and plating and painting industries.

Perovskite, reaction product of a harzburgite with Jurassic– Cretaceous accretionary wedge fluids (Western Carpathians, Slovakia): evidence from the whole-rock and mineral trace element data

Geologica Carpathica, 2016
Perovskite (Prv) was discovered in an abyssal harzburgite from a “mélange” type blueschist-bearing accretionary wedge of the Western Carpathians (Meliata Unit, Slovakia). Perovskite-1 formation in serpentinized orthopyroxene may be simplified by the mass-

Full Waveform Modeling of Bridgmanite Fabric‐Induced Seismic Discontinuities in the Mid‐Mantle: Implications for Double Underside Reflections Beneath Subduction Zones

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Mid‐mantle (660–2,000 km) seismic observations are commonly attributed to thermo‐chemical heterogeneities or phase transitions, yet many observed features remain difficult to reconcile with these mechanisms alone. It has been shown that the depth‐dependent behavior of bridgmanite deformation generates a strain‐induced seismic discontinuity ...

Pervasively Thin Anatolian Lithosphere With Elevated Upper Mantle Temperatures in the East: Insights From Bayesian Thermo‐Compositional Inversion

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract Uplift and widespread Late Miocene‐present magmatism in Anatolia are commonly attributed to lithospheric thinning, possibly facilitated by the arrival of hot mantle plume material. There are various lines of evidence for thin present‐day lithosphere, but the spatial extent and degree of lithospheric thinning and the underlying mantle ...
