komatiitic dunite in massive cumulate lithologies, which are interpreted to represent lava channels or <strong>the</strong><br />
channel-flow facies <strong>of</strong> channelized sheet flows and high-level sills. These environments are important, as<br />
<strong>the</strong>y are <strong>the</strong> favoured facies to host Ni-Cu-(PGE) mineralization (Lesher 1989). This is consistent with <strong>the</strong><br />
presence <strong>of</strong> komatiite-hosted Ni-Cu-(PGE) deposits only within <strong>the</strong> Kidd–Munro (e.g., Marbridge, Alexo,<br />
and Dundonald) and Tisdale assemblages (e.g., Texmont, Redstone, Hart, and Langmuir deposits).<br />
Table 6. Summary <strong>of</strong> geochemical (or lithological) and textural facies for <strong>the</strong> komatiitic rocks in different assemblages <strong>of</strong> <strong>the</strong><br />
Abitibi greenstone belt (modified <strong>from</strong> Houlé 2001).<br />
