Influence of C–O–H–Cl-Fluids on Melting Phase Relations of the System Peridotite-Basalt: Experiments at 4.0 GPa

Part of the Springer Mineralogy book series (MINERAL)


The article presents the results of experiments at pressure 4.0 GPa and temperature 1400 °C on the influence of fluids (H2O, H2O + CO2, H2O + HCl) on the composition of restite and magma formed during the melting of the peridotite-basalt-(K, Na)2CO3 system as a model analogue of the mantle reservoir contaminated with protoliths of subducted oceanic crust. The composition of the fluid has a significant impact on the phase relations. In “dry” conditions and with H2O fluid alkaline melts of phonolite type are formed, at H2O + CO2 fluid composition—trachiandezybasalts, with H2O + HCl fluid—riodacite melts. The alkaline melts coexist with an olivine-free restite pyroxene-phlogopite composition. Critical relations between fluid and silicate melt are observed in the water-bearing system. Interaction of supercritical fluid melts with peridotite restite leads to the formation of clinopyroxene, K-amphibole, phlogopite, carbonate, quenching silicate globules. Newly formed clinopyroxene and K-amphibole are in reactionary relations with olivine, orthopyroxene and clinopyroxene of peridotite restite. The revealed effects testify to instability of olivine at melting of peridotite-basalt mixture in the presence of fluid, effective influence of fluid composition on phase composition and critical ratios.
