However, there is still considerable deb<strong>at</strong>e regardingthe origin of the mineraliz<strong>at</strong>ion in those deposits and more recent work hasshown th<strong>at</strong> PGE mineraliz<strong>at</strong>ion occurs in a very wide range of other geologicalsettings. There have been substantial improvements in our understandingof the magm<strong>at</strong>ic, magm<strong>at</strong>ic-hydrothermal, hydrothermal, and tectonometamorphicprocesses th<strong>at</strong> may mobilize and concentr<strong>at</strong>e PGEs, as well assignificant improvements in analytical techniques. These improvements nowallow us to accur<strong>at</strong>ely measure the abundance of virtually every elementth<strong>at</strong> is relevant to the petrogenesis of the PGE mineraliz<strong>at</strong>ion <strong>at</strong> parts perbillion to parts per trillion levels. Significant opportunities exist to increaseour understanding of the petrogenesis, metallogenesis, and prospectivity ofmafic-ultramafic intrusions.This project represents Phase 2 of a joint Ontario Ministry of NorthernDevelopment and Mines (MNDM) / Mineral Explor<strong>at</strong>ion Research Centre(MERC) / Geological Survey of Canada (GSC) study focusing on the petrogenesis,metallogenesis, and prospectivity of mafic-ultramafic intrusions inOntario. This phase will involve detailed petrographic studies, mineral chemicalanalysis, and whole-rock geochemical analyses for a broad range of traceand ultr<strong>at</strong>race elements relevant to the petrogenesis of the intrusions and the
