AbstractThe McFaulds Lake greenstone belt (MLGB) is an extensive (>200 km long), arcuate-shaped, Meso- to Neoarchean, greenstone belt located in the central part of the Oxford-Stull domain of northern Ontario. The MLGB records a history of episodic volcanism, sedimentation, ultramafic-felsic intrusive activity and tectonism spanning from at least 2.83 to 2.66 Ga. Supracrustal rocks are tentatively subdivided into 7 tectonostratigraphic assemblages based on mapping, U-Pb geochronology, and geophysical interpretation. Mafic and ultramafic intrusive rocks comprise at least two distinct suites: a mafic-dominated, large layered intrusive suite represented by the Highbank-Fishtrap intrusive complex that was emplaced at ca. 2810 Ma, and an ultramafic to mafic intrusive suite termed the Ring of Fire intrusive suite. The latter comprises an ultramafic-dominated subsuite with significant Cr-Ni-Cu-PGE mineralization, and a mafic-dominated subsuite that contains significant Fe-Ti-V-(P) mineralization that was emplaced at ca. 2734 Ma.
Summary(Plain Language Summary, not published)
The Targeted Geoscience Initiative (TGI-4) is a collaborative federal geoscience program that provides industry with the next generation of geoscience knowledge and innovative techniques to better detect buried mineral deposits, thereby reducing some of the risks of exploration. This volume summarizes 22 research activities completed under the TGI-4 Ni-Cu-PGE-Cr ore systems project that focused on revised and new geologic models for Ni-Cu-PGE, PGE-Cu and Cr deposits, innovative techniques for determining potential fertility of intrusion (Ni-Cu-PGE), and defining pathfinders for Ni-Cu-PGE mineralization.
