PETROLOGIC DATA

Rock Number: 1

Rock Type: granodiorite
Descriptors:
augened
biotite
Field Description:

-light grey sub-gneissic as an old augen foliation with discreet BO segregation augen--> feldspar and quartz and appear to be an leucosome rather than phenocryst
-old foliation unloaded by buff GRDR pegmatite and outcrop crossed by younger cataclastic fabric producing sigmoidal offset patterns that probably would have been kink bands in a finer rock
-these discreet shears are 2 to 5 cm wide and show core of communication and late potassic alteration
-few vague schlieren and amphibole inclusions
