Abstract
The δ O values of phosphatic microfossils recovered from NW Ireland are used to determine the timing and magnitude of cooling associated with the onset of the Carboniferous glaciation. icrofossil fish δ Oapatite demonstrates a +2.4‰ (V-SMOW) shift, which, once corrected for δ O changes owing to evolving ice volumes, equates to an approximate 4.5 °C reduction in equatorial sea surface temperature between the earliest Asbian and the mid- Brigantian (late Visean). Both conodont and microfossil fish δ O indicate stabilization of an 'icehouse' climate during the Brigantian and into the Serpukhovian. Substantial late Visean cooling identified herein is in good agreement with global glacioeustatic records.
