PETROLOGIC DATA
Rock Number: 1
-layered sequence of sheared mega-crystic GRDR, sheared ampb. and 5 to 50 cm mylonite zones
-mylonites are porphyroclastic with a high degree of rolling and sygmoidal distortion of clasts, quartz and feldspar
-these zones appear to be a fault re-activation feature as the original cataclasis is cut by pink magnetiferous pegmatite which are inturned destroyed in mylonite zones
-there is no diff. in attitude of the 2 shearing directions
