Abstract

The dolerites and gabbros of the Tertiary central complex of Slieve Gullion, NE Ireland, represent a suite of tholeiitic magmas (varying from tholeiitic basalt to tholeiitic andesite, Gamble 1979 a ) which crystallized in the root-zone of a shield volcano. The ubiquity of biotite suggests that the magmas were hydrous and, in addition, both silicate (olivine) and oxide (Ti-magnetite) phases show evidence for oxidation at high temperatures.
