The platinum-group minerals (PGM) are a diverse group of minerals that concentrate the
platinum-group elements (PGE; Os, Ir, Ru, Rh, Pt, and Pd). At the time of writing, the …

The CM chondrites are samples of primitive water-rich asteroids formed during the early
solar system. They record significant interaction between liquid water and silicate rock …

Abstract On September 24, 2023, NASA's OSIRIS‐REx mission dropped a capsule to Earth
containing~ 120 g of pristine carbonaceous regolith from Bennu. We describe the delivery …

In Earth and planetary sciences, the chemical composition of chondritic meteorites provides
an essential reference to constrain the composition and differentiation history of planetary …

The delivery of water to the inner Solar System, including Earth, is still a debated topic. A
preferential role for hydrated asteroids in this process is supported by isotopic …

A quantitative understanding of the elemental and isotopic fractionations recorded in the
compositions of the chondritic meteorites would provide fundamental constraints for …

About 435 mineral species have been identified in meteorites including native elements,
metals and metallic alloys, carbides, nitrides and oxynitrides, phosphides, silicides, sulfides …

Stable potassium isotopes are one of the emerging non-traditional isotope systems enabled
in recent years by the advance of Multi-Collector Inductively-Coupled-Plasma Mass …

Evolved interstellar ices observed in dense protostellar molecular clouds may arguably be
considered as part of precometary materials that will later fall on primitive telluric planets …

The Paris meteorite is a weakly altered CM chondrite that has been discovered recently
(Hewins et al., 2014). Its matrix offers the opportunity to search for well-preserved pristine …
