Xenon in the Inclusions of Canyon Diablo and Toluca Iron Meteorites
The concentration and isotopic composition of xenon is reported in two samples of Canyon Diablo graphite and in three coexisting mineral phases from a silicate inclusion of Toluca. The existence of large 129rXe anomalies in iron meteorites is confirmed. Formation intervals of about 200 m.y. after an initial 129I/127I = 3 × 10-3 are calculated. Within the limits of experimental error the xenon appears to be a mixture of atmospheric and average-carbonaceous-chondrite-type xenon. No fissiogenic xenon could be identified.
