Search for aqueous fluid inclusions in a carbonaceous chondrite using X-ray micro-tomography combined with FIB micro-sampling.

Abstract

Search for aqueous fluid inclusions from carbonate and sulfide mineral grains in a carbonaceous chondrite has been made using X-ray CT combined with FIB. We observed a large number of fluid inclusion candidates including one (∼2 μm) in calcite that seems to have a bubble and a tiny solid daughter crystal inside.
