PETROLOGIC DATA
Rock Number: 1
-layered grey and white slightly augened gneiss
-local zones of more intense crushing 10 to 20 cm wide form layers of mylonite gneiss
-some vague biotite schlieren, highly flattened in the foliation, may have been amphibolite inclusions
-layered appearance largely comes from sheared pegmatite lee
-the rock is probably granitic in origin, but whether it was affiliated with CWB or teh grey porphyry is impossible to determine
-if necessary chemical analysis could probably tell
