Research Interests

• Igneous stratigraphy, petrology and PGE mineralization in the River Valley Intrusion, central Ontario; in collaboration with M. Easton, O.G.S. and J. Hrominchuk, M.Sc. candidate (LU).
• Character and genesis of PGE-Cu-Ni mineralization and their host rocks in the paleoproterozic EBLI-type layered intrusions in central Ontario; in collaboration with M.Lesher and R.Keays (LU), D.Peck (MEM).
• Metamorphic, tectonic and geochronologic history of paleoproterozoic intrusions and associated supracrustal rocks in the Grenville Front Tectonic Zone, central Ontario; in collaboration with M.Easton and F. Corfu (OGS) and E.Murphy (recently completed M.Sc. candiate, LU).
• Metamorphism of banded iron formations and paragenesis of associated Au-pyrrhotite-Arsenopyrite mineralization; in collaboration with A.Armitage (Comaplex Minerals/LU M.Sc.), G.Deschutter (Falconbridge/LU M.Sc), A. McDonald (LU), S.Goff (DIAND, Yellowknife).
