Meteorites are a remarkable resource. They capture the imagination of people worldwide
with their spectacular entry through Earth's atmosphere as fireballs, and their exotic …

Inductively coupled plasma mass spectrometry (ICP-MS) is a new technique for elemental
and isotopic analysis which combines the remarkable characteristics of the ICP for atomizing …

Studies of material returned from Cb asteroid Ryugu have revealed considerable
mineralogical and chemical heterogeneity, stemming primarily from brecciation and …

The Hayabusa2 spacecraft explored asteroid Ryugu and brought its surface materials to
Earth. Ryugu samples resemble Ivuna-type (CI) chondrites—the most chemically primitive …

The isotopic compositions of samples returned from Cb-type asteroid Ryugu and Ivuna-type
(CI) chondrites are distinct from other carbonaceous chondrites, which has led to the …

The origin of volatile elements in Mars and whether these elements derive from the inner or
outer solar system is unclear. Here we show that Mars exhibits nucleosynthetic zinc (Zn) …

Elements with differing siderophile affinities provide insights into various stages of planetary
accretion. The isotopic anomalies they exhibit offer a deeper understanding of the materials …

Volatile elements are key to understanding the accretion and differentiation processes that
formed the terrestrial planets. Relative to the solar photosphere or carbonaceous Ivuna-type …

Samples returned from the carbonaceous asteroid (162173) Ryugu by the Hayabusa2
mission revealed that Ryugu is composed of materials consistent with CI chondrites and …

Nucleosynthetic isotope anomalies of planetary materials provide insight into their genetic
ties, informing our understanding of early Solar System isotopic architecture and evolution …
