The concentration and distribution of water in the Earth has influenced its evolution
throughout its history. Even at the trace levels contained in the planet's deep interior (mantle …

The highly siderophile elements (HSE: Os, Ir, Ru, Rh, Pt, Pd, Re, Au) are key tracers of
planetary accretion and differentiation processes due to their affinity for metal relative to …

The platinum-group elements (PGEs; Os, Ir, Ru, Rh, Pt, Pd), along with rhenium and gold,
are grouped together as the highly siderophile elements (HSEs), defined by their extreme …

We re-examine the conditions at which core formation in the Moon may have occurred by
linking the observed lunar mantle depletions of 15 siderophile elements, including volatile …

Hydrogen (H) and carbon (C) have probably been delivered to the Earth mainly during
accretion processes at High Temperature (HT) and High Pressure (HP) and at variable …

Phase equilibrium experiments were conducted on a synthetic rock composition matching
that of the northern volcanic plains of Mercury as measured by the MErcury Surface, Space …

Earth's core contains∼ 10% of a light element that may be a combination of Si, S, C, O or H,
with Si potentially being the major light element. Metal-silicate partitioning of siderophile …

Gallium concentration (normalized to CI chondrites) in the mantle is at the same level as that
of lithophile elements with similar volatility, implying that there must be little to no gallium in …

The existence of resolvable 182 W/184 W deficits in modern ocean island basalts (OIB)
relative to the bulk silicate Earth has raised questions about the relationship of these rocks to …

The formation and evolution of our solar system started approximately 4.6 billion years ago
through the gravitational collapse of a small part of a giant molecular cloud, ie the pre-solar …
