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 …

Meteorites provide vast amounts of information on the make up and history of the solar
system. Physical properties are a critical component to provide this information. This is a …

In Earth and planetary sciences, the chemical composition of chondritic meteorites provides
an essential reference to constrain the composition and differentiation history of planetary …

We have analyzed the chemically and isotopically well‐characterized insoluble organic
matter (IOM) extracted from 51 unequilibrated chondrites (8 CR, 9 CM, 1 CI, 3 ungrouped C …

The carbonaceous asteroid Ryugu has been explored by the Hayabusa2 spacecraft to
elucidate the actual nature of hydrous asteroids. Laboratory analyses revealed that the …

The mineralogy and bulk compositions of the matrices of the CR chondrites MET 00426 and
QUE 99177 have been studied using a combination of SEM, EPMA, and TEM techniques …

We have examined the spectral reflectance properties and available modal mineralogies of
39 CM carbonaceous chondrites to determine their range of spectral variability and to …

Our knowledge of the internal structure of asteroids is, so far, indirect–relying entirely on
inferences from remote sensing observations of the surface, and theoretical modeling of …

On the microscale, the Winchcombe CM carbonaceous chondrite contains a number of
lithological units with a variety of degrees of aqueous alteration. However, an understanding …

Winchcombe is a CM chondrite that fell in England on February 28, 2021. Its rapid retrieval
was well characterized. Within two polished sections of Winchcombe, terrestrial phases …
