Abstract
Non-thermal escape of oxygen by recombination of exospheric O_2^+ combined with diffusive separation of gases at lower altitude provides a mechanism through which the Martian atmosphere may be enriched in ^(18)O relative to ^(16)O. Measurement of the abundance of ^(18)O relative to ^(16)O together with a determination of the turbopause may be used to develop important constraints on the history of Martian volatiles. Models for the interpretation of these data are developed and discussed in light of present information.
