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 …

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

Direct links between carbonaceous chondrites and their parent bodies in the solar system
are rare. The Winchcombe meteorite is the most accurately recorded carbonaceous …

INTRODUCTION Carbonaceous asteroids formed early in Solar System history and
experienced varying degrees of aqueous (water-rock) and thermal alteration. Most models …

Samples from asteroid Ryugu returned by the Hayabusa2 mission contain evidence of
extensive alteration by aqueous fluids and appear related to the CI chondrites. To …

Carbonatites (sensu lato) are distinguished on a mineralogical-genetic basis as primary,
high-temperature magmatic rocks as opposed to low-temperature, carbothermal, deuteric …

We report new mineralogical, petrographic and noble gas analyses of the carbonaceous
chondrite meteorites Y-82162 (C1/2 ung), Y-980115 (CI1), Y-86029 (CI1), Y-86720 (C2 …

The Paris meteorite is a weakly altered CM chondrite that has been discovered recently
(Hewins et al., 2014). Its matrix offers the opportunity to search for well-preserved pristine …

The Winchcombe meteorite is a CM chondrite breccia composed of eight distinct lithological
units plus a cataclastic matrix. The degree of aqueous alteration varies between intensely …

We report a systematic oxygen isotopic survey of Ca-carbonates in nine different CM
chondrites characterized by different degrees of alteration, from the least altered known to …
