PETROLOGIC DATA
Rock Number: 1
-starting at the last station the rock has become an increasingly complex and varied shear intrusive and inclusion complex
-the intrusive rocks are varied but dominantly GRDR and granitic pegmatites
-inclusions that can be recognized are amphibolites probably from basalt and hornblende wackes
-felsic sediments of present are too sheared to recognize
-sheared CWB TNLT is a major unit, however there is a pinkish-grey gine grained GRDR that is common that I don't recognize from CWB
-it's fine grained, CI of 2, slightly rusty and augened with 35% quartz and pink and white feldspars
-the outcrops are chopped up by a late anastomosing leuco granite to pegmatite vein network that is also deformed and rodded
-inclusions are variable from 5 to 15% on the outcrop
-sample of fine grained GRDR
