Volatile elements such as hydrogen, carbon, nitrogen and oxygen are essential ingredients
to build habitable worlds like Earth, but their origin and evolution on terrestrial planets …

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 …

A variety of lines of evidence show that water was widely available during the earliest
geological history of the solar system. Water played a significant role in the cosmochemical …

CM chondrites are aqueously altered rocks that contain∼ 9wt% H2O+ (ie, indigenous water)
bound in phyllosilicates; also present are clumps of serpentine-tochilinite intergrowths …

A systematic survey of 57 different paragenetic modes distributed among 5659 mineral
species reveals patterns in the diversity and distribution of minerals related to their evolving …

Astronomical observations have shown that protoplanetary disks are dynamic objects
through which mass is transported and accreted by the central star. This transport causes …

Major advances in deciphering the record of nebula processes in chondrites can be
attributed to analytical improvements that allow coordinated isotopic and mineralogical …

We present detailed electron microprobe analyses and oxygen three-isotope measurements
by high precision secondary ion mass spectrometry on 45 type I (FeO-poor) …

In order to investigate the nature of organics at the time of their accretion into chondrite
parent bodies, as well as their subsequent evolution with aqueous alteration, we have …

CM carbonaceous chondrites are samples of incompletely serpentinized primitive asteroids.
Using position sensitive detector X-ray diffraction (PSD-XRD) and a pattern strip** …
