A displaced and metamorphosed peralkaline granite related to the late Proterozoic Labrador and Gardar suites: the Doolough Granite of County Mayo, northwest Ireland
The chemically and lithologically distinct Doolough Granite from the Annagh Division in northwest County Mayo, Ireland, includes part of the northwesternmost exposures of Precambrian basement in Europe. The Doolough Granite is similar to Precambrian granitic intrusions found in Labrador and southwes...
