The H2O solubility of alkali basaltic melts: an experimental study
Experiments were conducted to determine the water solubility of alkali basalts from Etna, Stromboli and Vesuvius volcanoes, Italy. The basaltic melts were equilibrated at 1,200°C with pure water, under oxidized conditions, and at pressures ranging from 163 to 3,842 bars. Our results show that at pressures above 1 kbar, alkali basalts dissolve more water than typical mid-ocean ridge basalts (MOR...
متن کاملContinuous Gradations among Primary Carbonatitic, Kimberlitic, Melilititic, Basaltic, Picritic, and Komatiitic Melts in Equilibrium with Garnet Lherzolite at 3–8GPa
Multianvil melting experiments in the system CaO–MgO–Al2O3– SiO2–CO2 (CMAS–CO2) at 3–8 GPa, 1340–1800 C, involving the garnet lherzolite phase assemblage in equilibrium with CO2-bearing melts, yield continuous gradations in melt composition between carbonatite, kimberlite, melilitite, komatiite, picrite, and basalt melts. The phase relations encompass a divariant surface in P–T space. Compariso...
متن کاملEffects of F, B20 a and P205 on the solubility of water in haplogranite melts compared to natural silicate melts
The effects of F, B203 and P205 on the H 2 0 solubility in a haplogranite liquid (36wt .% SiO2, 39 wt. % NaA1Si3Os, 25 wt. % KAISi3Os) have been determined at 0.5, 1, 2, and 3 kb and 800, 850, and 900 ~ The H20 solubility increases with increasing F and B content of the melt. The H 2 0 solubility increase is more important at high pressure (2 and 3 kb) than at low pressure (0.5 kb). At 2 kb and...
متن کاملCo2 Solubility in Martian Basalts and Applications to Atmospheric Evolution
Introduction: A strong early Martian greenhouse atmosphere is required to account for evidence of liquid water on the surface of Mars [e.g. 1]. Many models of Mars’ atmospheric evolution incorporate magmatic outgassing fluxes of CO2 based on analogy to terrestrial magmas [2-5]. Here we investigate the solubility of carbon dioxide in Martian analogue basaltic melts at 2.0 GPa to constrain this i...
متن کاملDispelling some myths about the CO2 solubility in ionic liquids.
Ionic liquids have been objects of extensive research for physical sorption of CO2 and a number of myths have been perpetuated in the literature, for lack of a critical analysis, concerning their potential for CO2 capture. This study carries a critical analysis of a number of widely accepted ideas and others not so well accepted that have been repeatedly expressed in the literature concerning t...
