Abstract

The evidence forin situ produced fission xenon from244Pu in rock 14321 is presented. The inferred abundance ratio244Pu/238U is found to be consistent with values observed in a meteorite. Data from a stepwise release of the xenon permits a characterization of the trapped component, which can be shown to be distinct from solar xenon. We discuss the evidence for the presence of fission gases and of uncorrelated radiogenic argon in this and in other Apollo 14 rocks and some implications regarding their origin.
