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 …

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 …

Coupled information about the time-dependent production and temperature-dependent
diffusion of radiogenic argon in feldspars can be used to constrain the thermal evolution …

Abstract New petrography and 40Ar‐39Ar ages have been obtained for 1–3 mm sized rock
fragments from Apollo 16 Station 13 soil 63503 (North Ray crater ejecta) and chips from …

A detailed oxygen isotope study of the acapulcoites, lodranites, winonaites, brachinites and
various related achondrites has been undertaken to investigate the nature of their precursor …

Ordinary chondrites contain two phosphate minerals, merrillite and chlorapatite, both of
which are secondary minerals that developed in response to metamorphism on the …

Many igneous rocks contain mineral assemblages that are not appropriate for application of
common mineral equilibria or oxybarometers to estimate oxygen fugacity. Spinel-structured …

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) …

New major-and trace-element abundances, highly siderophile element (HSE: Os, Ir, Ru, Pt,
Pd, Re) abundances, and oxygen and rhenium–osmium isotope data are reported for …
