Summary:Radio-element-rich plutons (Barnesmore, Galway) are 'permitted', metalliferous intrusions, with secondary autunite and torbernite in fracture zones traversing the most fractionated facies. Uranium mineralization is described from the radio-element-poor 'forceful' plutons of Donegal and Leinster. In the Main Donegal pluton, primary uraninite mineralization occurs within NE-trending biotite pegmatite zones which may represent annealed shear zones. Extensive U-rich peat deposits occur over the Tullow pluton and are spatially related to transverse fracture zones. They are related either to radio-element-rich adamellite or radioactive, fluorapatite-bearing quartz breccias. [R.E.]
