I think, however, further proof is required as to its being of the same age as the rock which alters the Carboniferous Limestone near Carlingford: it rather differs in appearance and mineral composition from the Leinster granite, containing other micas, and notably by the occurrence in some places of albiteGoogle Scholar (Haughton, , Quart. Journ. Geol. Soc. vols. xii. and xiv.), though I believe that this feldspar is not so important a constituent as has been supposed.Google Scholar
