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 …

Fine-grained rims (FGRs) are ubiquitous in chondrites. They consist of unequilibrated
mineral assemblages that surround chondrules and refractory inclusions. As such, they carry …

We present here a review of the characteristics of CR carbonaceous chondrite meteorites.
Over the past three decades, our knowledge and understanding of the scientific value of the …

Recent observations made by the authors revealed the activation of stress induced
amorphization and sliding at grain boundary in olivine [1], a mechanism which is expected to …

Micrometeorites (MMs) recovered from surface snow near the Dome Fuji Station, Antarctica
are almost free from terrestrial weathering and contain very primitive materials, and are …

The morphology, molecular composition, and distribution of organic matter (OM) were
investigated in a suite of CR chondrites to better constrain its hydrothermal evolution …

The rheological properties of amorphous olivine thin films deposited by pulsed laser
deposition have been studied based on ambient temperature nanoindentation under …

In order to understand the nature of the dust that accreted onto chondrules in the nebula and
to unravel the conditions of formation of fine grained rims (FGRs), we studied three of the …

We review the mineralogy, petrology, and abundance of petrological type 1 extraterrestrial
material. Such material has been completely altered by aqueous processing on its parent …

For the first time, the influence of glass composition on the vapor hydration kinetics of the
French AVM nuclear waste glass simulants was investigated. Three complex borosilicate …
