Résumé(disponible en anglais seulement)
The mafic-dominated Big Mac, Fishtrap Lake, Highbank Lake, and Oxtoby Lake, the ultramafic-dominated Max, and the mafic-ultramafic Wabassi Main intrusions in the Oxford-Stull and Uchi domains of the Superior Province show significant potential for Fe-Ti-V-(P), Ni-Cu-(PGE), and/or Cr-(PGE) mineralization. The broadly layered Big Mac intrusion appears to have crystallized from an evolved high Fe-Ti basaltic parental magma that was injected from a feeder conduit below the northern part of the intrusion. The Fishtrap Lake and Highbank Lake intrusions represent parts of a large layered mafic-dominated igneous complex that formed from the injection of several pulses of basaltic magma. The genetically associated Max and Wabassi Main intrusions have crystallized from more primitive, basaltic parental magmas that were injected from a feeder conduit below the northwestern part of the Wabassi Main layered intrusion. In this magmatic system, the Max intrusion represents a magmatic conduit. The Oxtoby Lake intrusion appears to have crystallized from a differentiated basaltic parental magma and may represent an isolated intrusion.
