Plate tectonics and volcanism involve the formation, migration, and interaction of magma and gas. Experiments show that melt inclusions subjected to a thermal gradient migrate through olivine crystals, under the kinetic control of crystal-melt interface mechanisms. Exsolved gas bubbles remain fixed and eventually separate from the melt. Scaled to thermal gradients in Earth's mantle and geological times, our results account for the grain-scale segregation of primitive melts, reinterpret CO2-rich…

Melt Inclusions in Basaltic and Related Volcanic Rocks
Melt inclusions are small parcels of melt trapped in crystals within magmatic systems, and are analogous to fluid inclusions formed by trapping of hydrothermal and other fluids during mineral growth…
The eclogite engine: Chemical geodynamics as a Galileo thermometer
Migrating and incipient ridges and triple junctions sample the heterogeneous mantle created by plate tectonics and crustal stoping. The result is a yo-yo vertical convection mode that fertilizes,…
Melt variability in percolated peridotite: an experimental study applied to reactive migration of tholeiitic basalt in the upper mantle
Melt-rock reaction in the upper mantle is recorded in a variety of ultramafic rocks and is an important process in modifying melt composition on its way from the source region towards the surface.…
Subduction-related fluid occurrence in mantle revealed by residual pressure and isotopic compositions of fluid inclusion
An active convergent plate boundary comprises dynamic material circulation system where materials risen up from descending oceanic plate partly go back to the Earth’s surface. An evaluation of the…
Fluid-magmatic interaction between Glaucophane schist and olivine: Experimental modeling under the conditions of a thermal gradient
The subduction of a lithospheric plate into the mantle in subduction zones is accompanied by increase of temperature and pressure. The occurring mineral reactions of dehydration result in release of…

Intracrystalline melt migration in deformed olivine revealed by trace element compositions and polyphase solid inclusions
Abstract. Melt transport mechanisms have an important impact on the chemical composition of the percolated host rock and the migrating melts. Melt migration is usually assumed to occur at grain…
Timescales of convection in magma chambers below the Mid-Atlantic ridge from melt inclusions investigations
Closed hopper and complex swallowtail morphologies of olivine microcrysts have been described in the past in both mid-oceanic ridge basalts and subaerial tholeitic volcanoes and indicate fluctuations…
Transcrystalline melt migration in clinopyroxene
Glass inclusions in clinopyroxene phenocrysts from La Sommata (Vulcano Island, Aeolian Arc) were reheated and submitted to a sustained thermal gradient. Each remelted inclusion undergoes a transient…
