PETROLOGIC DATA
Rock Number: 1
-back into the cataclastic rocks
-this outcrop is a mixture of three rock types possibly four
-the easily identifiable ones are pink granitic mylonite and mafic hornblende wacke
-the bulk of the outcrop is a light grey homogeneous equigranular well foliated sand textured with sporadic pink garnet, most pinhead, but up to 4mm
-the rock comprised 2 to 3 % BO, 35% quartz, and the remainder is snowy white feldspar
-there is no apparent layering but the rock is well foliated
-it is intruded and brecciated by late white aplitic GRDR which is also sheared
-the texture of the rock looks like a sandstone but it's unlayered massive appearance and it's apparent including of the mafic wacke suggests it could be a TNLT intrusive, however the presence of garnet is not common in Cross Lake Intrusions
