PETROLOGIC DATA
Rock Number: 1
-majority of outcrop is fine grained mafic rock--little textural variation, could be massive basalt but I think it is a fine grained phase of the gabbro with alteration veins
Rock Number: 2
-NW edge of outcrop is banded silicate facies iron formation with siliceous layers and layers of massive magnetite
-probably an inclusion sliver on edge of gabbro
-there appear to be inclusion of iron formation in gabbro upto 2 or 3 m from contact
