Lithology Comments

Aug 14, 2015 (L Hall) - Sublayer Breccia is a fragmental rock with an igneous textured noritic groundmass bearing inclusions of mafic and ultramafic character of contentious origin. The Footwall Breccia has an igneous groundmass; however it is more felsic tending towards granitic composition. The inclusions in Footwall Breccia are derived from the footwall rocks, in this case primarily Levack Gneiss.
