The primordial gases of eight unequilibrated ordinary chondrites are strongly fractionated with respect to" cosmic" proportions. The absolute amounts are roughly proportional to the degree of disequilibration. Apparently, ordinary chondrites originally contained considerably larger amounts of primordial rare gases.
