The Earth took 30–40 million years to accrete from smaller 'planetesimals'. Many of these
planetesimals had metallic iron cores and during growth of the Earth this metal re …

The detection of strongly magnetized ancient crust on Mars is one of the most surprising
outcomes of recent Mars exploration, and provides important insight about the history and …

We propose a new model of Earth's bulk composition based on enstatite chondrites (E-
chondrites), the only chondrite group isotopically identical to the Earth. This model allows a …

We performed experiments to separate the effects of temperature, pressure and metal
composition on the metal-silicate partitioning of V, Ni, Co, Mn and Si in order to refine the …

The past several years have seen dramatic developments in the study of planetary magnetic
fields, including a wealth of new data, mainly from the Galilean satellites and Mars, together …

The mantles of both Earth and Mars are more oxidized than would be expected based on
low pressure equilibration of molten silicate and alloy during their magma ocean stages …

Chemical composition is a fundamental property of any planetary body. The bulk
composition is determined by starting materials (the compositions of which are set by …

The range in density and compressibility of Mercurian melt compositions was determined to
better understand the products of a possible Mercurian magma ocean and subsequent …

Partitioning of sulphur between liquid Fe-rich metals and silicates (DS met/sil) was
investigated at temperatures from 1800° C to 2400° C, pressures from 2 to 23 GPa and …

Silicon isotopic data from a range of lunar samples are presented to assess the degree of
heterogeneity of the lunar mantle and its similarity to bulk silicate Earth (BSE). Multi-collector …
