Research Abstract |
A primitive carbonaceous chondrite was treated by hydrochloric acid and hydro fluoric acid and a carbonaceous residue was obtained. The residue was separated with an ultra-high centrifugation system and two fractions were obtained. Noble gas isotopic measurement was conducted for the fractions and extremely high concentrations of noble gases were detected for the heavier fraction.
