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 …

[HTML][HTML] Linking asteroids and meteorites to the primordial planetesimal population
RC Greenwood, TH Burbine, IA Franchi - Geochimica et Cosmochimica …, 2020 - Elsevier
Meteorites provide a unique insight into early Solar System processes. However, to fully
interpret this record requires that these meteorites are related back to their source asteroids …

A history of mild shocks experienced by the regolith particles on hydrated asteroid Ryugu
Micrometeorites, a possible major source of Earth's water, are thought to form from explosive
dispersal of hydrated chondritic materials during impact events on their parental asteroids …

Modal abundances of coarse-grained (> 5 μm) components within CI-chondrites and their individual clasts–Mixing of various lithologies on the CI parent body (ies)
For the bulk rocks of CI chondrites, various values are given for the modal abundance of
matrix (95–100 vol%) and the accompanying mineral constituents. Here, we have …

Classification of CM chondrite breccias—Implications for the evaluation of samples from the OSIRIS‐REx and Hayabusa 2 missions
CM chondrites are complex impact (mostly regolith) breccias, in which lithic clasts show
various degrees of aqueous alteration. Here, we investigated the degree of alteration of …

Experimentally induced thermal fatigue on lunar and eucrite meteorites—Influence of the mineralogy on rock breakdown
M Patzek, O Rüsch - Journal of Geophysical Research: Planets, 2022 - Wiley Online Library
Thermal fatigue has been proven to be of fundamental importance for the nature and
evolution of surfaces of airless bodies in the solar system. It is a rock erosive process acting …
