Objectif TO STUDY THE ISOTOPE CHARACTERISTICS OF A VARIETY OF MINERAL DEPOSITS AND TO EXAMINE WAYS IN WHICH THE RESULTS CAN BE APPLIED DURING TARGET SELECTION AND PLANNING IN EXPLORATION THIS PROJECT WILL STUDY AT LEAST THREE MINERALISED AREAS IN THE CALEDONIDE BASEMENT OF IRELAND. BASEMENT TARGETS HAVE BEEN CHOSEN WITH THE AIM OF STUDYING A DIVERSIFIED SUITE OF METALS AND DEPOSITS, AND BECAUSE IT IS CONSIDERED THAT THE CHANCES OF UTILISING THE RESULTS IN A PREDICTIVE MANNER ARE MUCH HIGHER HERE THAN IN THE COVER SEDIMENTS. THE TARGETS CHOSEN ARE ALL CURRENTLY BEING EVALUATED BY EXPLORATION COMPANIES: 1. SOUTHEAST IRELAND: TUNGSTEN-BEARING MICROGRANITES AND LITHIUM-BEARING PEGMATITES WILL BE THE PRIME TARGETS HERE, ALTHOUGH BASE METAL MINERALISATION IN SEDIMENTS AND VOLCANICS MAY ALSO BE EXAMINED. 2. LONGFORD-DOWN MASSIF: THIS AREA CONTAINS A SERIES OF VEIN-TYPE GOLD-BASE METALS - BARYTE DEPOSITS. 3. CONNEMARA: DALDRADIAN-HOSTED TUNGSTEN AND BASE METAL DEPOSITS FROM AN EXTENSIVE AREA WILL BE STUDIED. 4. CHARLESTOWN: THIS IS A VOLCANOGENIC COPPER DEPOSITS IN THE WEST OF IRELAND; IT HAS THE LOWEST PRIORITY AND WILL BE ATTEMPTED ONLY IF CIRCRUMSTANCES PERMIT. UMSTANCES PERMIT. THE GEOLOGICAL FRAMEWORK OF ALL TARGETS WILL BE FULLY STUDIED. AND ALL APPROPRIATE GEOLOGICAL RESEARCH WILL BE COMPLETED. A STUDY OF THE ORE TEXTURAL DEVELOPMENT OF EACH DEPOSIT, TO INCLUDE THE TEXTURAL CHARACTERISTICS FO ALL MINEAL PHASES, WILL BE AN INTEGRAL PART OF THE WORK. A VARIETY OF ISOTOPE STUDIES WILL BE PERFORMED, WHICH MAY INCLUDE SULPHUR, LEAD, OXYGEN, STRONTIUM, HYDROGEN AND CARBON. IN THE CASE OF LONGFORD-DOWN, ATTENTION WILL BE FOCUSSED ON THE APPLICABILITY OF LEAD ISOTOPES. ANCILLARY STUDIES WILL BE UNDERTAKEN WHEREVER NECESSARY TO PROPERLY UNDERSTAND TEXTURAL DEVELOPMENT OR INTERPRET THE ISOTOPE RESULTS.
