Low-temperature aqueous alteration of chondrites
Chondritic meteorites (chondrites) contain evidence for the interaction of liquid water with
the interiors of small bodies early in Solar System history. Here we review the processes …

The isotopic links from planet forming regions to the solar system
Isotopic ratios provide a powerful tool for understanding the origins of materials, including
the volatile and refractory matter within solar system bodies. Recent high sensitivity …

A temporal shift of chondrule generation from the inner to outer Solar System inferred from oxygen isotopes and Al-Mg chronology of chondrules from primitive CM and …
Deciphering the spatial and temporal evolution of chondrules allows for a better
understanding of how asteroidal seeds formed, migrated, and eventually accreted into …

The H2O content of the ureilite parent body
The fate of highly volatile elements (H, C, F, Cl and S) during planetary accretion and
differentiation is debated. Recent analyses of water in non-carbonaceous chondrites (RC …

Antimony isotope fractionation during evaporation from Sb chloride solution
L Chen, S Li, M Zhang, X Liu, Z Zhu - Chemical Geology, 2024 - Elsevier
The evaporation process plays a crucial role in the geochemical transport of volatile
elements, such as antimony (Sb). However, there is limited understanding regarding the …

Volatile-depletion processing of the building blocks of Earth and Mars as recorded by potassium isotopes
The stable potassium isotopic ratios (41 K/39 K) of Earth and Mars have been interpreted to
reflect either nucleosynthetic isotope anomalies or volatility-driven K depletion. Chondrites …

Upper limits of water contents in olivine and orthopyroxene of equilibrated chondrites and several achondrites
Hydroxyl defects in nominally anhydrous minerals (NAMs) were potential carriers of water in
the early Solar System and might have contributed to the accretion of terrestrial water. To …

New evidence for wet accretion of inner solar system planetesimals from meteorites Chelyabinsk and Benenitra
We investigated the hydrogen isotopic compositions and water contents of pyroxenes in two
recent ordinary chondrite falls, namely, Chelyabinsk (2013 fall) and Benenitra (2018 fall) …

The high-temperature origin of hydrogen in enstatite chondrite chondrules and implications for the origin of terrestrial water
Due to their numerous isotopic similarities to terrestrial rocks, enstatite chondrites (ECs) are
commonly proposed as Earth's main building blocks. Although ECs contain sufficient H …

An exploration of whether Earth can be built from chondritic components, not bulk chondrites
CMOD Alexander - Geochimica et Cosmochimica Acta, 2022 - Elsevier
Here, two of a range of possible models are explored that assume that:(i) two of the main
chondritic components (chondrules and refractory inclusions) dominated the Earth's building …
