Primitive liquid water of the solar system in an aqueous altered carbonaceous chondrite

Abstract

Non-destructive 3D observation of the aqueous altered CM chondrite Sutter’s Mill using scanning- imaging x-ray microscopy (SIXM) showed that some of calcite and enstatite grains contain two-phase inclusion, which is most probably composed of liquid water and bubbles. This water should be primitive water responsible for aqueous alteration in an asteroid in the early solar system.
