N2  - Abstract
The chief metamorphic minerals are described and, in addition to those reported by Lamplugh, cordierite (at scattered localities along the structural axis) and staurolite (at Glion Darragh, Archal-lagan) are found to occur. The distribution of metamorphic minerals recorded by Lamplugh is confirmed. The age relation of the new minerals to the movements is deduced from microscopic evidence. This is: early folding and development of biotite; relaxation of stress and development of cordierite; shearing and recrystallization of biotite along planes of fracture-cleavage; high grade metamorphism at Archallagan which outlasted the fracture-cleavage movements.

It is concluded that the postulate of a buried granite beneath the axial belt most readily accounts for the distribution of the metamorphism
