Experimentally based water budgets for dehydrating slabs and consequences for arc magma generation
Phase diagrams of hydrous mid-ocean ridge (MOR) basalts to 330 km depth and of hydrous peridotites to 250 km depth are compiled for conditions characteristic for subduction zones. A synthesis of ourExpand

Experimentally Determined Phase Relations in Hydrous Peridotites to 6·5 GPa and their Consequences on the Dynamics of Subduction Zones
Fluid-saturated subsolidus experiments from 2 0 to 6 5 GPa, and from 680 to 800 C have been performed on three model peridotites in the system Na2O–CaO–FeO–MgO–Al2O3–SiO2– H2O (NCFMASH). AmphiboleExpand

H2O transport and release in subduction zones : experimental constraints on basaltic and andesitic systems
Phase relationships in natural andesitic and synthetic basaltic systems were experimentally investigated from 2.2 to 7.7 GPa, and 550°C to 950°C, in the presence of an aqueous fluid, in order toExpand

Carbonate stability and fluid composition in subducted oceanic crust: an experimental study on H2O–CO2-bearing basalts
Carbonates and hydrates are common products of the alteration of the upper basaltic crust in modern oceans. However, phase relationships and devolatilization reactions in altered CO2-bearingExpand

The transport of carbon and hydrogen in subducted oceanic crust: An experimental study to 5 GPa
Abstract Carbon and hydrogen residence time in the Earth's interior is controlled by complex phase equilibria attained in the subduction zone environment. Carbonic fluid/melts are highly mobile,Expand

Alkali in phlogopite and amphibole and their effects on phase relations in metasomatized peridotites: a high-pressure study
Subsolidus phase relations for a K-doped lherzolite are investigated in the model system K2O–Na2O–CaO–FeO–MgO–Al2O3–SiO2–H2O at 1.5–6.0 GPa and 680–1,000°C. Phlogopite is ubiquitous and coexists withExpand
