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 …

A number of distinct methodologies are available for determining the oxygen isotope
composition of minerals and rocks, these include laser-assisted fluorination, secondary ion …

Meteorites provide a unique insight into early Solar System processes. However, to fully
interpret this record requires that these meteorites are related back to their source asteroids …

How much of Earth's compositional variation dates to processes that occurred during planet
formation remains an unanswered question. High-precision tungsten isotopic data from …

The samarium-146 (146Sm)–neodymium-142 (142Nd) short-lived decay system (half-life of
103 million years) is a powerful tracer of the early mantle-crust evolution of planetary bodies …

Highly evolved lithology distributes across the Moon sparsely but serves as a critical record
of the extensive differentiation processes of lunar magmas. In contrast to the Apollo-returned …

Hotspot volcanic rocks are formed under conditions that differ from conventional plate
tectonic boundary magmatic processes and are compositionally distinct from mid-oceanic …

Angrites are medium-to coarse-grained (up to 2–3mm), unbrecciated and substantially
unshocked igneous rocks of roughly basaltic composition. They are the most alkali-depleted …

Whole rock Δ 17 O and nucleosynthetic isotopic variations for chromium, titanium, nickel,
and molybdenum in meteorites define two isotopically distinct populations: carbonaceous …

Unlike the other terrestrial planets, Earth has a substantial silica-rich continental crust with a
bulk andesitic composition. A small number of meteorites with andesitic bulk compositions …
