Separation of carrier phase of primordial noble gas component trapped in primitive chondrites with ultra-high centrifugal force

用盐酸和氢氟酸对原始碳质球粒陨石进行处理，得到碳质残渣。用超高离心机对残渣进行分离，得到两个馏分。对馏分进行了稀有气体同位素测量，对于较重的馏分检测到了极高浓度的稀有气体。

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.
