About 435 mineral species have been identified in meteorites including native elements,
metals and metallic alloys, carbides, nitrides and oxynitrides, phosphides, silicides, sulfides …

Here we show that bulk H, C and N elemental and isotopic analyses can be used to classify
CM and CR chondrites. These meteorites in both groups form well-defined trends in plots of …

The relative differences in the degree of hydration should be reflected in any classification
scheme for aqueously altered meteorites. Here we report the bulk mineralogies and degree …

Carbonaceous chondrites are meteoritic fragments of asteroids that avoided the geological
reprocessing of larger planets and allow laboratory probing of early solar-nebula materials …

We report the bulk C abundances, and C and O isotopic compositions of carbonates in 64
CM chondrites, 14 CR chondrites, 2 CI chondrites, LEW 85332 (C2), Kaba (CV 3), and …

Carbonaceous chondrites record processes of aqueous alteration in the presence of
hydrated and hydroxylated minerals, which could have provided a source of water in the …

In this work, infrared transmission spectra (2–25 μm range, 5000–400 cm− 1) of 40
carbonaceous chondrites were analyzed (21 CMs, 5 CVs, 6 CRs, 3 CKs, 3 C2s and 2 CIs) …

Determining compositional trends among individual minerals is key to understanding the
thermodynamic conditions under which they formed and altered, and is also essential to …

Meteorites are fascinating cosmic visitors. Using accessible language, this book documents
the history of mineralogy and meteorite research, summarizes the mineralogical …

The CR chondrites carry one of the most pristine records of the solar nebula materials that
accreted to form planetesimals. They have experienced very variable degrees of aqueous …
