Rapid reequilibration of H2O and oxygen fugacity in olivine-hosted melt inclusions
TL;DR: In this paper, it was shown that, contrary to the widely held view, H 2 O loss or gain in melt inclusions is not limited by redox reactions and significant fluxes of H + through the host olivine are possible on very short time scales.
Journal ArticleDOI
Post-entrapment modification of volatiles and oxygen fugacity in olivine-hosted melt inclusions
TL;DR: In this paper, the authors show that the CO 2 and S concentrations within an included melt decrease with progressive diffusive H 2 O loss, and propose that this occurs due to dehydration-induced changes to the internal pressure of the inclusion.
Journal ArticleDOI
Fractional crystallization of high-K arc magmas: biotite- versus amphibole-dominated fractionation series in the Dariv Igneous Complex, Western Mongolia
TL;DR: The Dariv Igneous complex of Western Mongolia is composed of a moderately hydrous, alkaline fractionation sequence ranging from phlogopite-bearing ultramafic and mafic cumulates to quartz-monzonites to late-stage felsic (63-75 wt% SiO2) dikes as mentioned in this paper.
Journal ArticleDOI
Neoproterozoic to early Phanerozoic rise in island arc redox state due to deep ocean oxygenation and increased marine sulfate levels.
TL;DR: Newly compiled Fe3+/ΣFe and V/Sc ratios presented here indicate that island arc rocks became more oxidized 800–400 Ma, which provides evidence that the oxidized nature of modern island arc magmas is due to an oxidized mantle source and represents a rare example of a change in the surface biogeochemistry influencing the igneous rock record.
Journal ArticleDOI
Fluid flow and Al transport during quartz-kyanite vein formation, Unst, Shetland Islands, Scotland
Claire E. Bucholz,Jay J. Ague +1 more
TL;DR: In this article, the authors investigated the geochemical alteration and mobility of Al associated with channelized metamorphic fluid infiltration during the Caledonian Orogeny, and concluded that the quartz-kyanite veins and their selvages were produced by regional-scale advective mass transfer by means of focused fluid flow along a thrust fault zone.
