Melting relations in the chloride–carbonate–silicate systems at high-pressure and the model for formation of alkalic diamond–forming liquids in the upper mantle
The experiments in the model system CaMgSi2O6–(Na2CO3 ,C aCO3)–KCl are performed at 5 GPa and 1400–1600 °C in order to study the phase relations, including liquid immiscibility, in the… Expand

Crystal-melt equilibria involving potassium-bearing clinopyroxene as indicator of mantle-derived ultrahigh-potassic liquids: an analytical review
Abstract Crystal–liquid equilibria, including phase relationships of minerals with silicate and/or carbonate melts, are reviewed in order to understand the occurrence of clinopyroxene with up to 2… Expand

Interaction of Biotite–Amphibole Gneiss with H2O–CO2–(K, Na)Cl Fluids at 550 MPa and 750 and 800°С: Experimental Study and Applications to Dehydration and Partial Melting in the Middle Crust
To constrain effects of chloride-bearing H2O^CO2 fluids on complex natural assemblages during high-grade metamorphism and anatexis, we report the results of experiments on the interaction of biotite^… Expand

Experimental model for alkalic chloride-rich liquids in the upper mantle
Abstract In order to expand an applicability of a model for evolution of the alkalic chloride-rich liquids in the upper mantle additional runs in chloride–carbonate–silicate systems involving model… Expand

Links between Carbonatite and Kimberlite Melts in Chloride–Carbonate–Silicate Systems: Experiments and Application to Natural Assemblages
Recent data suggest an active role for chloride-bearing alkali carbonatitic melts in the formation and evolution of kimberlites, whereas experiments indicate that chlorides could be responsible for… Expand

Precambrian ultra-hot orogenic factory: Making and reworking of continental crust
Abstract Mechanisms of Precambrian orogeny and their contribution to the origin of ultrahigh temperature granulites, granite-greenstone terranes and net crustal growth remain debatable. Here, we use… Expand

Halogens in High-Grade Metamorphism
This chapter reviews factors, which control the distribution of the two major halogens, F and Cl, in high-grade metamorphic rocks; their compositional correlations and partitioning between minerals;… Expand

Origin of Cl-bearing silica-rich melt inclusions in diamonds: Experimental evidence for an eclogite connection
Melting phase relations of a model chloride- and carbonate-bearing eclogite have been studied at 7.0–10.5 GPa and 1200–1675 °C. The mineral assemblage coexisting with partial melts is garnet,… Expand
