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

Oxygen is the dominant element in our planetary system. It is therefore remarkable that it
shows substantial isotopic diversity both in mass-dependent fractionation, because it is a …

The age of iron meteorites implies that accretion of protoplanets began during the first
millions of years of the solar system. Due to the heat generated by 26Al decay, many early …

The fate of highly volatile elements (H, C, F, Cl and S) during planetary accretion and
differentiation is debated. Recent analyses of water in non-carbonaceous chondrites (RC …

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 …

Erg Chech (EC) 002 is a meteorite with andesitic composition, potentially recording the lava
crystallization and crust formation of its parent body. Nucleosynthetic Cr isotope composition …

After accretion of meteorite parent bodies, larger and smaller collisions have led to
significant modifications of these bodies. Involved processes include excavation of material …

We present the results of melting experiments on a suite of carbonaceous and ordinary
chondritic compositions (CV, CM, CI, H and LL) performed at low pressure (0.1–13.1 MPa) …

The ranges in chemical composition of ancient achondrite meteorites are key to
understanding the diversity and geochemical evolution of planetary building blocks. These …
