PETROLOGIC DATA
Rock Number: 1
-since last station gradual increase in mafics and in grain size
-also, slows increase in inclusions, now recognizable, at least as supracrustals
-gradual increase in number and size of pegmatites that appear as swarm
Rock Number: 2
-swarm of parallel pegs, KF rich and quartz poor with black mafic clots that appear to be BO and CL(?)
-SEE SAMPLE
-there is some shearing on dike margins and movement between dikes in counting rock (ie-foliation in GRDR is rotated slightly) so dikes are probably occupying an en echelon fault site.
