Abstract
The whole-rock delta(18)O of mudrocks, as well as the delta(18)O of th e clay-sized silicate fraction, does not change in any systematic mann er over Paleozoic and late Proterozoic time. Therefore, the delta(18)O of the ocean has not changed (except a per mil or so as the result of glaciation/deglaciation) over the last billion years of Earth history .
