Abstract
Initial investigations designed to test the potential for gold in a series of lithologies associated with tourmalinites and coticules in the neighbourhood of the Caledonian Leinster Granite of southeast Ireland are reported. The results of geological mapping, geochemical analyses and panning of stream sediments indicate that significant levels of gold are associated with some tourmalinite zones. The possible exploration implication of this work is that tourmalinites have potential as target indicators, although secondary controls on mineralization are also important.
