Si- versus Mg-metasomatism at the crust–mantle interface: insights from experiments, natural observations and geochemical modeling
The slab–mantle interface in subduction zones is one of the geological boundaries with the most significant chemical potential gradients, which leads...

Metasomatism at a metapelite–ultramafic rock contact at the subduction interface: Insights into mass transfer and fluid flow at the mantle wedge corner
Metasomatism of the subducting slab and mantle wedge influences the rheological and chemical properties of rocks at the subduction zone interface. We...

A geochemical perspective on the genesis of Cenozoic basic volcanism in northeastern Turkey: an overview of metasomatism and heterogeneity of the sub-continental lithospheric mantle in a post-collisional setting
The post-collisional Cenozoic basic volcanic rocks in NE Turkey show temporal variations in whole-rock lithophile element and highly siderophile...

Meta-Ultramafic Rocks of the Maksyutov Complex, Southern Urals: High-Pressure Si–Al Metasomatism and Carbonatization at the Crust–Mantle Interface in the Subduction Zone
Abstract —The Maksyutov eclogite–blueschist Complex is characterized by a complicated fold-and-thrust structure that has been formed during the Late...

COH-fluid induced metasomatism of peridotites in the forearc mantle
Devolatilization of subducting lithologies liberates COH-fluids. These may become partially sequestered in peridotites in the slab and the overlying...
-
Arc volcano activity driven by small-scale metasomatism of the magma source
Arc volcanism arises from the release of fluids from the descending slab, which enables melting in the mantle wedge by lowering the solidus...

Evidence and timing of metasomatism of the lithospheric mantle before large-scale Deccan magmatism: Insights from the phlogopite–spinel–wehrlite xenoliths from Sarnu–Dandali alkaline igneous complex, Rajasthan, northwestern India
Wehrlite xenoliths recovered from lamprophyre dykes from Sarnu–Dandali alkaline igneous complex record three distinct events of modification in the...

Experimental constraints on the nature of multiphase solid inclusions and their bearing on mantle wedge metasomatism, Bohemian Massif
This study tests experimentally the hypothesis that calculated bulk compositions of multiphase solid inclusions present in minerals of ultrahigh...

Multistage Mantle Metasomatism during the Generation of Kimberlite Melts: Evidence from Mantle Xenoliths and Megacrysts of the Grib Kimberlite, Arkhangelsk, Russia
Major and trace element compositions of garnet, clinopyroxene, orthopyroxene, phlogopite, and ilmenite from garnet peridotite, ilmenite-bearing...

Geochemical insights into mantle metasomatism from cogenetic plutonic xenoliths in pyroclastic deposits of Gölcük volcano and their alkaline host rocks (Isparta, SW Turkey)
Lower Pliocene–Quaternary Gölcük volcano in SW Turkey, represented by potassic to ultrapotassic alkaline volcanics, is a well-preserved example with...

Multistage mantle metasomatism deciphered by Mg−Sr−Nd−Pb isotopes in the Leucite Hills lamproites
Cratonic lamproites bear extreme Sr−Nd−Pb isotopic compositions widely known as enriched mantle I (EMI), yet the origin of the EMI reservoir remains...

Experimental Study of Reactions Forming Phlogopite and Potassic Titanates as Mineral Indicators of Metasomatism in the Upper Mantle
Abstract—The paper summarizes authors' earlier and newly obtained experimental data on the formation of phlogopite and chromium-bearing potassium...

Progressive carbonation and Ca-metasomatism of serpentinized ultramafic rocks: insights from natural occurrences and hydrothermal experiments
Hydration, carbonation, and related metasomatism of mantle peridotite play a significant role in the global geochemical cycle. In this study, we...
