PETROLOGIC DATA
Rock Number: 1
-black HB-BO largely as inclusions in pegmatite although the SW side of outcrop is all ampb
-extensive tectonic and injection layering but where it is reasonably undisturbed the ampb is massive and featureless
-not likely to be volcanic ampb
-probably a med. gr. mesogabbro of the old mafic suite
Rock Number: 2
-single BO +/- MV granite with irregular pegmatite patches that pass into continuous peg. dikes
-this is crosscut by later less deformed pegs.--quartz poor graphic MC
