Abstract

The “space problem” in north-west Donegal is analysed; structures of country rocks and granite-quartzite contacts, together with marginal granitization, suggest that two space-forming processes operated together. The inter-relationship of these mechanical and chemical processes in Gweedore and Cloghaneely suggests a dual rhythm within Read's (1949) granite series.
