Abundances of the elements: Meteoritic and solar
New abundance tables have been compiled for Cl chondrites and the solar photosphere and corona, based on a critical review of the literature to mid-1988. The meteorite data are generally accurate to
Interstellar grains in meteorites: I. Isolation of SiC, graphite and diamond; size distributions of SiC and graphite
A procedure has been developed for isolating three types of interstellar grains from primitive meteorites, in >90% purity and yields of generally ≥70%, and is here applied to the Murchison C2M
Solar-system abundances of the elements
Abstract A new abundance table has been compiled, based on a critical review of all C1 chondrite analyses up to mid-1982. Where C1 data were inaccurate or lacking, data for other meteorite classes
Origin, age, and composition of meteorites
This paper attempts to bring together and evaluate all significant evidence on the origin of meteorites.The iron meteorites seem to have formed at low pressures. Laboratory evidence shows that the

About 20 g cm−2 intact organic carbon may have accumulated in the few hundred million years between the last cataclysmic impact and the beginning of life, which may have included some biologically important compounds that did not form by abiotic synthesis on Earth.

Review of available data shows only a few gross trends for the inner planets: FeO decreases with heliocentric distance, whereas volatiles are depleted and refractories are enriched in the smaller planets.
Interstellar diamonds in meteorites
Primitive meteorites contain up to 400 p.p.m. of a very fine-grained type of carbon, noncommittally called Cδ1. It apparently conies from outside the Solar System, as it carries isotopically
Evidence for interstellar SiC in the Murray carbonaceous meteorite
Silicon carbide has been observed in the interstellar medium and in circumstellar shells. Although it might be expected to occur in primitive meteorites that contain other kinds of pre-solar
Samarium-146 in the Early Solar System: Evidence from Neodymium in the Allende Meteorite
A carbon-chromite fraction from the Allende C3V chondrite shows strikingly large isotopic enrichments of neodymium-142 and neodynium- 143, providing an improved estimate of the original abundance of extinct samarium-146 in the early solar system.
Distribution of gold and rhenium between nickel-iron and silicate melts: implications for the abundance of siderophile elements on the Earth and Moon
Abstract The distribution equilibrium of Au and Re between nickel-iron and basaltic melts was studied at 1400–1600°C, using radioactive tracers. Metal/silicate distribution coefficients were 1–3
