| dc.description.abstract | The Lac des Iles Complex is a Neoarchean polyphase mafic-ultramafic complex located in
the Marmion terrane of the Superior Province, 85 km north of Thunder Bay, Ontario, Canada.
The intrusive complex can be subdivided into two discrete subcomplexes: the ultramafic-
dominated North Lac des Iles Complex and the mafic-dominated South Lac des Iles Complex
(SLDIC). The SLDIC has been subdivided into the gabbronorite, breccia, norite, and diorite
domains. To date, economic Pd-rich mineralization has been discovered in both the breccia and
norite domains and occurs proximal to the contacts between the breccia and gabbronorite
domains and between the breccia and norite domains. The objectives of this study were to
i) evaluate the mechanisms of formation of the mineralized horizons near the contact between
the breccia and norite domains in the Offset and Creek zones of the SLDIC, and ii) assess the
tectonic setting in which the SLDIC formed. [...] | en_US |
