Abstract
Samples of the Bjurbole chondrite were artifically shocked at 70, 200 and 400 kbar. Analyses of Xe released in stepwise heating show progressively greater alteration of the I-Xe system with increasing shock intensity; it was no longer possible to infer an age or trapped Xe composition for the 400 kbar sample. Interpretations of the I-Xe and 40Ar/39Ar systems for the naturally shocked chondrites Kota-Kota, McKinney and Arapahoe are presented. The data for Arapahoe do not confirm the reported age and trapped Xe composition. -B.M.
