Extensive experimental studies show all major rocky elements (Si, Mg, Fe, Ni, Ca, Al, Na, K) dissolve in steam to a greater or lesser extent. We use these results to compute chemical equilibrium abundances of rocky element-bearing gases in steam atmospheres equilibrated with silicate magma oceans. Rocky elements partition into steam atmospheres as volatile hydroxide gases and via reaction with HF or HCl as volatile halide gases in much larger amounts than expected from their vapor pressures… Expand
Escape of rock-forming volatile elements and noble gases from planetary embryos
Abstract Large planetesimals and planetary embryos ranging from several hundred to a few thousand kilometers can develop magma oceans through mutual collisions, gravitational energy, and the heatingExpand
Evaporation of moderately volatile elements from silicate melts: experiments and theory
Abstract Moderately volatile elements (MVEs) are sensitive tracers of vaporisation in geological and cosmochemical processes owing to their balanced partitioning between vapour and condensed phases.Expand
Volatile element chemistry during accretion of the earth
Abstract We review some issues relevant to volatile element chemistry during accretion of the Earth with an emphasis on historical development of ideas during the past century and on issues we thinkExpand
Loss and Fractionation of Noble Gas Isotopes and Moderately Volatile Elements from Planetary Embryos and Early Venus, Earth and Mars
Here we discuss the current state of knowledge on how atmospheric escape processes can fractionate noble gas isotopes and moderately volatile rock-forming elements that populate primordialExpand
A metasomatic mechanism for the formation of Earth's earliest evolved crust
Abstract Following giant impacts the early Hadean Earth was shrouded in a steam atmosphere for durations on the order of 1 Ma. In order to investigate the potential of this atmosphere to fractionateExpand
Implications of K, Cu and Zn isotopes for the formation of tektites
Abstract Tektites are mm to cm sized glassy objects generated through high-energy meteoroid impacts on the surface of the Earth under high temperature and pressure, and reducing conditions. They areExpand
Tin isotopes indicative of liquid–vapour equilibration and separation in the Moon-forming disk
The depletion in moderately volatile elements in the Moon relative to Earth and comparison of the isotope compositions of the Moon and Earth have placed important constraints on models of lunarExpand
Potassium isotope compositions of carbonaceous and ordinary chondrites: Implications on the origin of volatile depletion in the early solar system
Abstract Among solar system materials there are variable degrees of depletion in moderately volatile elements (MVEs, such as Na, K, Rb, Cu, and Zn) relative to the proto-solar composition. WhetherExpand
Acquisition of terrestrial neon during accretion – A mixture of solar wind and planetary components
Abstract Earth’s mantle contains Ne resembling the solar wind implanted Ne-B component in meteorites (20Ne/22NeNe-B: ∼12.7). The atmosphere, instead, displays a “planetary” signature (20Ne/22NeAtm:Expand
Constraining the early evolution of Venus and Earth through atmospheric Ar, Ne isotope and bulk K/U ratios
Abstract The atmospheric noble gas isotope and elemental bulk ratios on Venus and Earth provide important information on their origin and evolution. If the protoplanets grew to a certain mass (i.e. >Expand
