Low-temperature aqueous alteration of chondrites

MR Lee, CMOD Alexander, A Bischoff… - Space Science …, 2025 - Springer
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

The H2O content of the ureilite parent body

LD Peterson, ME Newcombe, CMOD Alexander… - … et Cosmochimica Acta, 2023 - Elsevier
The fate of highly volatile elements (H, C, F, Cl and S) during planetary accretion and

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

Y Hu, F Moynier, X Yang - Earth and Planetary Science Letters, 2023 - Elsevier
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

D Harries, X Zhao, I Franchi - Meteoritics & Planetary Science, 2023 - Wiley Online Library
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 …

The high-temperature origin of hydrogen in enstatite chondrite chondrules and implications for the origin of terrestrial water

D Thomassin, L Piani, J Villeneuve, MC Caumon… - Earth and Planetary …, 2023 - Elsevier
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
