Presented here are the observations and interpretations from a comprehensive analysis of
16 representative particles returned from the C-type asteroid Ryugu by the Hayabusa2 …

Little is known about the origin of the spectral diversity of asteroids and what it says about
conditions in the protoplanetary disk. Here, we show that samples returned from Cb-type …

Chondrites are meteorites from undifferentiated parent bodies that provide fundamental
information about early Solar System evolution and planet formation. The element Cr is …

Among primitive meteorites, CR chondrites have peculiar isotopic compositions, the origin of
which is uncertain and may have involved contributions from primordial molecular cloud …

Fluids in subduction zones significantly influence element mobility, isotope fractionation, and
mass transfer. However, unraveling the source, composition, and redox state of fluids in …

Nucleosynthetic Fe isotopic anomalies in meteorites may be used to learn about the early
evolution of the solar system and to identify the origin and nature of the material that built the …

Enstatite achondrites (including aubrites) are the only differentiated meteorites that have
similar isotope compositions to the Earth-Moon system for most of the elements. However …

We report the first Ni and Cr stable isotope data for ureilite meteorites that are the mantle
residue of a carbon‐rich differentiated planet. Ureilites have similar Ni stable isotope …

Chromium (Cr) isotopes represent a powerful tool for tracing the redox conditions during
planetary magmatic evolution. However, so far, the systematic investigation of Cr isotope …

The diverse isotopic anomalies of meteorites demonstrate that the protoplanetary disc was
composed of components from different stellar sources, which mixed in the disc and formed …
