Abstract
The radiation age of the Norton County aubrite has been redetermined as 107 m.y. by the Ne21 Al26 method-much shorter than the earlier values of 220 m.y. and 500 m.y. obtained by the He3 H3 and Ar38 Ar39 methods. The new value no longer contradicts the notion that radiation ages of stony meteorites are governed by their lifetimes against collisional fragmentation.
