In this study we present the first Mg isotope data that record fate of during mineralisation atmospheric CO2 in ultramafic mine tailings. At Woodsreef Asbestos Mine, New South Wales, Australia, weathering waste sequesters significant amounts hydromagnesite [Mg5(CO3)4(OH)2·4H2O]. Mineralisation above-ground, sub-aerially stored tailings is driven by infiltration rainwater dissolving from bedrock...

Low-grade metamorphic hydrous minerals and carbonates occur in various settings on Mars Martian meteorites. We present constraints the stability of prehnite, zeolites, serpentine, by modeling influence H2O-CO2 fluids during low-grade metamorphism crust using compositions a basalt an ultramafic cumulate. In basaltic with 5 wt% fluid, our models predict prehnite less oxidized, CO2-poor conditions...

The petrology and geochemistry of serpentinized harzburgites within the Feather River Ophiolite in northern California were investigated to constrain the origin of serpentinization. Trace-element systematics indicate that serpentinization was associated almost solely with relatively low temperature hydrothermal addition of seawater and not with the addition of metamorphic fluids associated with...
