| Abstract | The Circum-Superior large igneous province that extends for over than 2500 km along the margin of the Superior Province hosts two of Canada's most important magmatic Ni-Cu-PGE districts: the Thompson
(northern Manitoba) and the Raglan (Nunavik, northern Quebec) nickel belts. The vast majority of the Ni-Cu-(PGE) mineralization in the Raglan belt occurs within a series of thick (50-200 m) lava channels and channelized sheet flows facies along the
contact between the early Proterozoic Povungnituk and younger Chukotat groups. This geological contact appears to be repeated in the 'Northern Permits' area located north of active mining area, however, although it contains lithologically similar
ultramafic-mafic units, it lacks significant mineralization. The overall metal endowment of these two panels is disparate; this research seeks to understand why the metal endowment is significantly different between these two areas. |
