Uredelgase in einigen Steinmeteoriten

Abstract

In the two chondrites Kapoeta and Abee outstanding rare gas content have been found. From the amount and isotopic composition it is concluded that primordial rare gases have been included in these meteorites. Kapoeta contains all rare gases in excess, while Abee has mainly the heavier rare gases as primordial component. The Ne 20 /Ne 22 —and A 36 /A 38 —ratios show large deviations from atmospheric Neon and Argon. No such large deviations could be found for Krypton and Xenon.
