The elemental and isotopic compositions of meteorites are expected to reflect several key
processes that occurred in the early solar system, including the migration of gas and dust …

Carbonaceous chondrites are some of the most primitive meteorites and derive from
planetesimals that formed a few million years after the beginning of the solar system. Here …

Nucleosynthetic isotope signatures in meteorites provide key insights into the structure and
dynamics of the solar protoplanetary disk and the accretion history of the planets. We …

Understanding the formation of our planetary system requires identification of the materials
from which it originated and the accretion processes that produced the planets. The …

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

Renazzo-type carbonaceous (CR) chondrites are distinct from most other chondrites in
having younger chondrule 26 Al-26 Mg ages, but the significance of these ages and whether …

Chondritic meteorites and their components formed in the protoplanetary disk surrounding
the nascent sun. We show here that the two volumetrically dominating components of …

We present here a review of the characteristics of CR carbonaceous chondrite meteorites.
Over the past three decades, our knowledge and understanding of the scientific value of the …

Meteorite magnetizations can provide rare insight into early Solar System evolution. Such
data take on new importance with recognition of the isotopic dichotomy between non …

We report on the petrology, magnesium isotopes and mass-independent 54 Cr/52 Cr
compositions (μ 54 Cr) of 42 chondrules from CV (Vigarano and NWA 3118) and CR (NWA …
