Origin of Isotopic Diversity among Carbonaceous Chondrites [PDF]
The Astrophysical Journal Letters, 2023 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.

Abundance, major element composition and size of components and matrix in CV, CO and Acfer 094 chondrites [PDF]
, 2023 The relative abundances and chemical compositions of the macroscopic components or “inclusions” (chondrules and refractory inclusions) and fine-grained mineral matrix in chondritic meteorites provide constraints on astrophysical theories of inclusion ...

Thermal alteration of CM carbonaceous chondrites: Mineralogical changes and metamorphic temperatures [PDF]
, 2021 The CM carbonaceous chondrite meteorites provide a record of low temperature aqueous reactions in the early solar system. A number of CM chondrites also experienced short-lived, post-hydration thermal metamorphism at temperatures of 200C to over 750C ...

The aqueous alteration of CM chondrites, a review
Geochimica et Cosmochimica Acta, 2021 The CM chondrites are samples of primitive water-rich asteroids formed during the early solar system. They record significant interaction between liquid water and silicate rock, resulting in a mineralogy dominated by hydrated secondary phases.

The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Geophysical Monograph Series, Page 229-246., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Geochimica et Cosmochimica Acta, 2021 A close relationship between CM and CO chondrites has been suggested by previous petrologic and isotopic studies, leading to the suggestion that they may originate from similar precursor materials or even a common parent body.

Polar Science, 2020 CM chondrites (CMs) are the most abundant group of carbonaceous chondrites. CMs experienced varying degrees of secondary aqueous alteration and heating that modified or destroyed their primitive features. We have studied three chondrites, Asuka (A) 12085,
