PETROLOGIC DATA
Rock Number: 1
-well foliated biege weathering gRDR TNLT, intruded by sub-horizontal vein networks and sills of buff leuco-quartz monzonite
-this has been intensivly passively folded by the 059 steep cataclastic foliation producing tight upright folds with a near horizontal axis
-this makes fold profiles observed on outcrop surface appear highly assymetric and disharmonic
-varying outcrop profiles add to the confusion resulting in a near random schlieric fabric
-thin mylonite zones are planar cutting the general cataclastic fabric but are offset on local 060 degree cataclastic planes
-this would seem to indicate the Whiskey Jack Compression zone had an extended period of activity that was probably pulsed
